  Specifications: 2JWY15010Q50G uses the AirTAC 2J angle-seat-valve ordering format: 2 ports / 2 positions, pneumatic actuation, SUS304 stainless steel, normally closed, water-hammer arrangement, DN 15, G 3/8 in process ports and a 50 mm actuator. Product Catalog Download Airtac Product Catalog (PDF) For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Model Code Explained Code Meaning for this listing 2J Pneumatically actuated 2-port / 2-position angle-seat valve W SUS304 stainless steel Y normally closed, water-hammer arrangement 150 DN 15 10 3/8 in Q50 50 mm actuator bore G G thread Technical Specifications Parameter Details Valve body material SUS304 stainless steel Catalog process-medium scope Compressed air and steam only for this Y arrangement; not for liquids Process-medium viscosity 600 mm²/s or less Process-medium temperature −20 to +180 °C; catalog dew-point note: −20 °C or below Ambient temperature −10 to +60 °C, subject to the medium/ambient-temperature relationship chart Control medium Compressed air / neutral gas filtered through a 40 µm filter element Maximum control pressure 10 bar for a 40 / 50 / 63 mm actuator Kv 4.8 Minimum pilot pressure Select from the catalog fluid-pressure / control-pressure curve for this arrangement Maximum operating differential pressure 16 bar Catalog weight 0.8 kg (800 g) The temperature relationship diagram must also be observed: higher process-medium temperature reduces the permitted ambient temperature. The chart spans 100–200 °C horizontally and 20–70 °C vertically; these are plotting ranges, not extensions of the limits above. The dashed relationship passes the marked 120 °C process-medium / 60 °C ambient point. Use the original diagram to determine the relationship at other temperatures; no numeric endpoint is inferred from the plotted line. Weight source: the exact action, nominal diameter, port and actuator row on 2022 printed page 191 and linked PDF page 1. The published kilogram value is converted to grams for this listing; 2J is not listed on the page-300 summary. For the Y water-hammer arrangement, the 2022 Chinese catalog specifies gas and steam and excludes liquids. Features and Operation Pneumatic pilot control permits operation without an electrical coil on the valve. The catalog describes low starting pressure and control of higher process pressure with lower pilot pressure; this statement does not itself establish an explosion-protection certification. The stainless-steel body and connecting components support corrosion resistance. PTFE sealing is used; verify the complete material list and actual medium compatibility for the application. The 45-degree angle-seat passage and streamlined internal shape reduce flow resistance. The catalog identifies a bronze filter element in the internal assembly to reduce impurity entry. The actuator has a visible position indicator for observing valve opening. The Chinese catalog describes replacing the indicator window with a limit switch or emergency manual device, but does not provide separately orderable accessory codes or a list of included accessories. The actuator control port uses a metal insert. A connection plate can mount a NAMUR solenoid valve; the reviewed pages do not name a specific matching NAMUR valve series or part number. The actuator can rotate through 360 degrees to simplify installation. Flow Direction and Pilot-Pressure Selection For this action code, the catalog shows the process medium entering above the seat, downward from the upper side of the valve piston. Follow the correct arrangement symbol and the A / P process-port and pilot-port labels in the drawing. The normally closed and normally open symbols are different. For K normally open and Y normally closed water-hammer models, the catalog curves plot process operating pressure from 0 to 16 bar against pilot pressure from 0 to 10 bar. Each line has a DN / actuator label; use the line for the actual combination. Do not use an axis limit as the minimum pilot pressure, or borrow a curve from another actuator diameter. External and Mounting Dimensions The dimensions below follow the DN / actuator row on 2022 printed page 192 and linked PDF page 2. Lettered callouts refer to the original inclined view; they are not interchangeable length, width and height values. The drawing labels the control port Q as G thread; the final G / T model suffix identifies the ordered process thread. Parameter Details A 162 mm AB 68 mm AC 22.5 mm AD 12 mm C 153 mm CA 140 mm ØD 66 mm E 44 mm H 27 mm 2-P, process ports 2 × G 3/8 in Q, actuator control port G1/4 QA 24 mm Valve-body inclination 45° For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Internal Components — Catalog Reference The cutaway is specifically labeled 2JS150-Q50. The following numbered parts and materials describe that illustrated assembly, not guaranteed spare-part compatibility or quantities for every 2J model. The selected S / W body material remains the material decoded for this listing.

Release system pressure and allow the system to cool before maintenance, inspection or installation. For dismantling a normally closed valve, the catalog requires air at pilot port 1 to move the piston into position before loosening the valve-body connection. Do not force the joint against the preloaded spring; the catalog warns of thread damage. The actuator contains a loaded spring and requires special dismantling tools. The catalog directs users who cannot perform this maintenance to return the valve to the manufacturer. Series Ordering Options Body codes are S = SUS316L and W = SUS304. Action codes are blank = normally closed without water hammer, Y = normally closed water-hammer arrangement and K = normally open. DN codes are 150 / 200 / 250 / 320; actuator codes are Q40 / Q50 / Q63 / Q80; process-thread codes are G and T (NPT). The specification table restricts which combinations are actually listed; these options do not form an unrestricted cross-product. Position switches, emergency manual devices, connection plates and NAMUR control valves are mentioned as possible arrangements, but the reviewed 2J pages give no accessory ordering codes or supplied-kit quantities. This listing does not promise those accessories are included.

Release system pressure and allow the system to cool before maintenance, inspection or installation. For dismantling a normally closed valve, the catalog requires air at pilot port 1 to move the piston into position before loosening the valve-body connection. Do not force the joint against the preloaded spring; the catalog warns of thread damage. The actuator contains a loaded spring and requires special dismantling tools. The catalog directs users who cannot perform this maintenance to return the valve to the manufacturer. Series Ordering Options Body codes are S = SUS316L and W = SUS304. Action codes are blank = normally closed without water hammer, Y = normally closed water-hammer arrangement and K = normally open. DN codes are 150 / 200 / 250 / 320; actuator codes are Q40 / Q50 / Q63 / Q80; process-thread codes are G and T (NPT). The specification table restricts which combinations are actually listed; these options do not form an unrestricted cross-product. Position switches, emergency manual devices, connection plates and NAMUR control valves are mentioned as possible arrangements, but the reviewed 2J pages give no accessory ordering codes or supplied-kit quantities. This listing does not promise those accessories are included.

  Airtac 2JSK series: pneumatic angle seat valve - 2JSK15010Q40T

  Specifications: 2JSK15010Q40T uses the AirTAC 2J angle-seat-valve ordering format: 2 ports / 2 positions, pneumatic actuation, SUS316L stainless steel, normally open, DN 15, NPT 3/8 in process ports and a 40 mm actuator. Product Catalog Download Airtac Product Catalog (PDF) For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Model Code Explained Code Meaning for this listing 2J Pneumatically actuated 2-port / 2-position angle-seat valve S SUS316L stainless steel K normally open 150 DN 15 10 3/8 in Q40 40 mm actuator bore T NPT thread Technical Specifications Parameter Details Valve body material SUS316L stainless steel Catalog process-medium scope Compressed air, liquid fluids, vacuum and steam Process-medium viscosity 600 mm²/s or less Process-medium temperature −20 to +180 °C; catalog dew-point note: −20 °C or below Ambient temperature −10 to +60 °C, subject to the medium/ambient-temperature relationship chart Control medium Compressed air / neutral gas filtered through a 40 µm filter element Maximum control pressure 10 bar for a 40 / 50 / 63 mm actuator Kv 4.4 Minimum pilot pressure Select from the catalog fluid-pressure / control-pressure curve for this arrangement Maximum operating differential pressure 16 bar Catalog weight 0.8 kg (800 g) The temperature relationship diagram must also be observed: higher process-medium temperature reduces the permitted ambient temperature. The chart spans 100–200 °C horizontally and 20–70 °C vertically; these are plotting ranges, not extensions of the limits above. The dashed relationship passes the marked 120 °C process-medium / 60 °C ambient point. Use the original diagram to determine the relationship at other temperatures; no numeric endpoint is inferred from the plotted line. Weight source: the exact action, nominal diameter, port and actuator row on 2022 printed page 191 and linked PDF page 1. The published kilogram value is converted to grams for this listing; 2J is not listed on the page-300 summary. Features and Operation Pneumatic pilot control permits operation without an electrical coil on the valve. The catalog describes low starting pressure and control of higher process pressure with lower pilot pressure; this statement does not itself establish an explosion-protection certification. The stainless-steel body and connecting components support corrosion resistance. PTFE sealing is used; verify the complete material list and actual medium compatibility for the application. The 45-degree angle-seat passage and streamlined internal shape reduce flow resistance. The catalog identifies a bronze filter element in the internal assembly to reduce impurity entry. The actuator has a visible position indicator for observing valve opening. The Chinese catalog describes replacing the indicator window with a limit switch or emergency manual device, but does not provide separately orderable accessory codes or a list of included accessories. The actuator control port uses a metal insert. A connection plate can mount a NAMUR solenoid valve; the reviewed pages do not name a specific matching NAMUR valve series or part number. The actuator can rotate through 360 degrees to simplify installation. Flow Direction and Pilot-Pressure Selection For this action code, the catalog shows the process medium entering below the seat, upward from the lower side of the valve piston. Follow the correct arrangement symbol and the A / P process-port and pilot-port labels in the drawing. The normally closed and normally open symbols are different. For K normally open and Y normally closed water-hammer models, the catalog curves plot process operating pressure from 0 to 16 bar against pilot pressure from 0 to 10 bar. Each line has a DN / actuator label; use the line for the actual combination. Do not use an axis limit as the minimum pilot pressure, or borrow a curve from another actuator diameter. External and Mounting Dimensions The dimensions below follow the DN / actuator row on 2022 printed page 192 and linked PDF page 2.

  Airtac 2JWY series: pneumatic angle seat valve - 2JWY32032Q80T

  Specifications: 2JWY32032Q80T uses the AirTAC 2J angle-seat-valve ordering format: 2 ports / 2 positions, pneumatic actuation, SUS304 stainless steel, normally closed, water-hammer arrangement, DN 32, NPT 1 1/4 in process ports and a 80 mm actuator. Product Catalog Download Airtac Product Catalog (PDF) For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Ordering Combination Requires Confirmation The individual codes can be decoded, but the catalog specification table does not list the normally closed, water-hammer arrangement combination with DN 32 and a 80 mm actuator. This model must be confirmed before ordering. No Kv, minimum pilot pressure, maximum operating differential pressure, weight or installed dimensions are assigned from a neighboring model. Model Code Explained Code Meaning for this listing 2J Pneumatically actuated 2-port / 2-position angle-seat valve W SUS304 stainless steel Y normally closed, water-hammer arrangement 320 DN 32 32 1 1/4 in Q80 80 mm actuator bore T NPT thread Technical Specifications Parameter Details Valve body material SUS304 stainless steel Catalog process-medium scope Compressed air and steam only for this Y arrangement; not for liquids Process-medium viscosity 600 mm²/s or less Process-medium temperature −20 to +180 °C; catalog dew-point note: −20 °C or below Ambient temperature −10 to +60 °C, subject to the medium/ambient-temperature relationship chart Control medium Compressed air / neutral gas filtered through a 40 µm filter element Maximum control pressure 7 bar for an 80 mm actuator The temperature relationship diagram must also be observed: higher process-medium temperature reduces the permitted ambient temperature. The chart spans 100–200 °C horizontally and 20–70 °C vertically; these are plotting ranges, not extensions of the limits above. The dashed relationship passes the marked 120 °C process-medium / 60 °C ambient point. Use the original diagram to determine the relationship at other temperatures; no numeric endpoint is inferred from the plotted line. For the Y water-hammer arrangement, the 2022 Chinese catalog specifies gas and steam and excludes liquids. Features and Operation Pneumatic pilot control permits operation without an electrical coil on the valve. The catalog describes low starting pressure and control of higher process pressure with lower pilot pressure; this statement does not itself establish an explosion-protection certification. The stainless-steel body and connecting components support corrosion resistance. PTFE sealing is used; verify the complete material list and actual medium compatibility for the application. The 45-degree angle-seat passage and streamlined internal shape reduce flow resistance. The catalog identifies a bronze filter element in the internal assembly to reduce impurity entry. The actuator has a visible position indicator for observing valve opening. The Chinese catalog describes replacing the indicator window with a limit switch or emergency manual device, but does not provide separately orderable accessory codes or a list of included accessories. The actuator control port uses a metal insert. A connection plate can mount a NAMUR solenoid valve; the reviewed pages do not name a specific matching NAMUR valve series or part number. The actuator can rotate through 360 degrees to simplify installation. Flow Direction and Pilot-Pressure Selection For this action code, the catalog shows the process medium entering above the seat, downward from the upper side of the valve piston. Follow the correct arrangement symbol and the A / P process-port and pilot-port labels in the drawing. The normally closed and normally open symbols are different. For K normally open and Y normally closed water-hammer models, the catalog curves plot process operating pressure from 0 to 16 bar against pilot pressure from 0 to 10 bar. Each line has a DN / actuator label; use the line for the actual combination. Do not use an axis limit as the minimum pilot pressure, or borrow a curve from another actuator diameter. External and Mounting Dimensions The exact action / actuator combination is not covered by the specification table. The general DN / actuator drawing is not assigned as a confirmed installed envelope for this unlisted configuration. For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Internal Components — Catalog Reference The cutaway is specifically labeled 2JS150-Q50. The following numbered parts and materials describe that illustrated assembly, not guaranteed spare-part compatibility or quantities for every 2J model. The selected S / W body material remains the material decoded for this listing.

Release system pressure and allow the system to cool before maintenance, inspection or installation. For dismantling a normally closed valve, the catalog requires air at pilot port 1 to move the piston into position before loosening the valve-body connection. Do not force the joint against the preloaded spring; the catalog warns of thread damage. The actuator contains a loaded spring and requires special dismantling tools. The catalog directs users who cannot perform this maintenance to return the valve to the manufacturer. Series Ordering Options Body codes are S = SUS316L and W = SUS304. Action codes are blank = normally closed without water hammer, Y = normally closed water-hammer arrangement and K = normally open. DN codes are 150 / 200 / 250 / 320; actuator codes are Q40 / Q50 / Q63 / Q80; process-thread codes are G and T (NPT). The specification table restricts which combinations are actually listed; these options do not form an unrestricted cross-product. Position switches, emergency manual devices, connection plates and NAMUR control valves are mentioned as possible arrangements, but the reviewed 2J pages give no accessory ordering codes or supplied-kit quantities. This listing does not promise those accessories are included.

  Airtac 2JWY series: pneumatic angle seat valve - 2JWY32032Q80G

  Specifications: 2JWY32032Q80G uses the AirTAC 2J angle-seat-valve ordering format: 2 ports / 2 positions, pneumatic actuation, SUS304 stainless steel, normally closed, water-hammer arrangement, DN 32, G 1 1/4 in process ports and a 80 mm actuator. Product Catalog Download Airtac Product Catalog (PDF) For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Ordering Combination Requires Confirmation The individual codes can be decoded, but the catalog specification table does not list the normally closed, water-hammer arrangement combination with DN 32 and a 80 mm actuator. This model must be confirmed before ordering. No Kv, minimum pilot pressure, maximum operating differential pressure, weight or installed dimensions are assigned from a neighboring model. Model Code Explained Code Meaning for this listing 2J Pneumatically actuated 2-port / 2-position angle-seat valve W SUS304 stainless steel Y normally closed, water-hammer arrangement 320 DN 32 32 1 1/4 in Q80 80 mm actuator bore G G thread Technical Specifications Parameter Details Valve body material SUS304 stainless steel Catalog process-medium scope Compressed air and steam only for this Y arrangement; not for liquids Process-medium viscosity 600 mm²/s or less Process-medium temperature −20 to +180 °C; catalog dew-point note: −20 °C or below Ambient temperature −10 to +60 °C, subject to the medium/ambient-temperature relationship chart Control medium Compressed air / neutral gas filtered through a 40 µm filter element Maximum control pressure 7 bar for an 80 mm actuator The temperature relationship diagram must also be observed: higher process-medium temperature reduces the permitted ambient temperature. The chart spans 100–200 °C horizontally and 20–70 °C vertically; these are plotting ranges, not extensions of the limits above. The dashed relationship passes the marked 120 °C process-medium / 60 °C ambient point. Use the original diagram to determine the relationship at other temperatures; no numeric endpoint is inferred from the plotted line. For the Y water-hammer arrangement, the 2022 Chinese catalog specifies gas and steam and excludes liquids. Features and Operation Pneumatic pilot control permits operation without an electrical coil on the valve. The catalog describes low starting pressure and control of higher process pressure with lower pilot pressure; this statement does not itself establish an explosion-protection certification. The stainless-steel body and connecting components support corrosion resistance. PTFE sealing is used; verify the complete material list and actual medium compatibility for the application. The 45-degree angle-seat passage and streamlined internal shape reduce flow resistance. The catalog identifies a bronze filter element in the internal assembly to reduce impurity entry. The actuator has a visible position indicator for observing valve opening. The Chinese catalog describes replacing the indicator window with a limit switch or emergency manual device, but does not provide separately orderable accessory codes or a list of included accessories.

The actuator control port uses a metal insert. A connection plate can mount a NAMUR solenoid valve; the reviewed pages do not name a specific matching NAMUR valve series or part number. The actuator can rotate through 360 degrees to simplify installation. Flow Direction and Pilot-Pressure Selection For this action code, the catalog shows the process medium entering above the seat, downward from the upper side of the valve piston. Follow the correct arrangement symbol and the A / P process-port and pilot-port labels in the drawing. The normally closed and normally open symbols are different. For K normally open and Y normally closed water-hammer models, the catalog curves plot process operating pressure from 0 to 16 bar against pilot pressure from 0 to 10 bar. Each line has a DN / actuator label; use the line for the actual combination. Do not use an axis limit as the minimum pilot pressure, or borrow a curve from another actuator diameter. External and Mounting Dimensions The exact action / actuator combination is not covered by the specification table. The general DN / actuator drawing is not assigned as a confirmed installed envelope for this unlisted configuration. For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Internal Components — Catalog Reference The cutaway is specifically labeled 2JS150-Q50. The following numbered parts and materials describe that illustrated assembly, not guaranteed spare-part compatibility or quantities for every 2J model. The selected S / W body material remains the material decoded for this listing.

Release system pressure and allow the system to cool before maintenance, inspection or installation. For dismantling a normally closed valve, the catalog requires air at pilot port 1 to move the piston into position before loosening the valve-body connection. Do not force the joint against the preloaded spring; the catalog warns of thread damage. The actuator contains a loaded spring and requires special dismantling tools. The catalog directs users who cannot perform this maintenance to return the valve to the manufacturer. Series Ordering Options Body codes are S = SUS316L and W = SUS304. Action codes are blank = normally closed without water hammer, Y = normally closed water-hammer arrangement and K = normally open. DN codes are 150 / 200 / 250 / 320; actuator codes are Q40 / Q50 / Q63 / Q80; process-thread codes are G and T (NPT). The specification table restricts which combinations are actually listed; these options do not form an unrestricted cross-product. Position switches, emergency manual devices, connection plates and NAMUR control valves are mentioned as possible arrangements, but the reviewed 2J pages give no accessory ordering codes or supplied-kit quantities. This listing does not promise those accessories are included.

  Airtac 2JW series: pneumatic angle seat valve - 2JW25025Q50T

  Specifications: 2JW25025Q50T uses the AirTAC 2J angle-seat-valve ordering format: 2 ports / 2 positions, pneumatic actuation, SUS304 stainless steel, normally closed, no-water-hammer arrangement, DN 25, NPT 1 in process ports and a 50 mm actuator. Product Catalog Download Airtac Product Catalog (PDF) For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Ordering Combination Requires Confirmation The individual codes can be decoded, but the catalog specification table does not list the normally closed, no-water-hammer arrangement combination with DN 25 and a 50 mm actuator. This model must be confirmed before ordering. No Kv, minimum pilot pressure, maximum operating differential pressure, weight or installed dimensions are assigned from a neighboring model. Model Code Explained Code Meaning for this listing 2J Pneumatically actuated 2-port / 2-position angle-seat valve W SUS304 stainless steel (blank action code) normally closed, no-water-hammer arrangement 250 DN 25 25 1 in Q50 50 mm actuator bore T NPT thread Technical Specifications Parameter Details Valve body material SUS304 stainless steel Catalog process-medium scope Compressed air, liquid fluids, vacuum and steam Process-medium viscosity 600 mm²/s or less Process-medium temperature −20 to +180 °C; catalog dew-point note: −20 °C or below Ambient temperature −10 to +60 °C, subject to the medium/ambient-temperature relationship chart Control medium Compressed air / neutral gas filtered through a 40 µm filter element Maximum control pressure 10 bar for a 40 / 50 / 63 mm actuator The temperature relationship diagram must also be observed: higher process-medium temperature reduces the permitted ambient temperature. The chart spans 100–200 °C horizontally and 20–70 °C vertically; these are plotting ranges, not extensions of the limits above. The dashed relationship passes the marked 120 °C process-medium / 60 °C ambient point. Use the original diagram to determine the relationship at other temperatures; no numeric endpoint is inferred from the plotted line. Features and Operation Pneumatic pilot control permits operation without an electrical coil on the valve. The catalog describes low starting pressure and control of higher process pressure with lower pilot pressure; this statement does not itself establish an explosion-protection certification. The stainless-steel body and connecting components support corrosion resistance. PTFE sealing is used; verify the complete material list and actual medium compatibility for the application. The 45-degree angle-seat passage and streamlined internal shape reduce flow resistance. The catalog identifies a bronze filter element in the internal assembly to reduce impurity entry. The actuator has a visible position indicator for observing valve opening. The Chinese catalog describes replacing the indicator window with a limit switch or emergency manual device, but does not provide separately orderable accessory codes or a list of included accessories.

  Airtac 2JSY series: pneumatic angle seat valve - 2JSY32032Q80G

  Specifications: 2JSY32032Q80G uses the AirTAC 2J angle-seat-valve ordering format: 2 ports / 2 positions, pneumatic actuation, SUS316L stainless steel, normally closed, water-hammer arrangement, DN 32, G 1 1/4 in process ports and a 80 mm actuator. Product Catalog Download Airtac Product Catalog (PDF) For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog. Ordering Combination Requires Confirmation The individual codes can be decoded, but the catalog specification table does not list the normally closed, water-hammer arrangement combination with DN 32 and a 80 mm actuator. This model must be confirmed before ordering. No Kv, minimum pilot pressure, maximum operating differential pressure, weight or installed dimensions are assigned from a neighboring model. Model Code Explained Code Meaning for this listing 2J Pneumatically actuated 2-port / 2-position angle-seat valve S SUS316L stainless steel Y normally closed, water-hammer arrangement 320 DN 32 32 1 1/4 in Q80 80 mm actuator bore G G thread Technical Specifications Parameter Details Valve body material SUS316L stainless steel Catalog process-medium scope Compressed air and steam only for this Y arrangement; not for liquids Process-medium viscosity 600 mm²/s or less Process-medium temperature −20 to +180 °C; catalog dew-point note: −20 °C or below Ambient temperature −10 to +60 °C, subject to the medium/ambient-temperature relationship chart Control medium Compressed air / neutral gas filtered through a 40 µm filter element Maximum control pressure 7 bar for an 80 mm actuator The temperature relationship diagram must also be observed: higher process-medium temperature reduces the permitted ambient temperature. The chart spans 100–200 °C horizontally and 20–70 °C vertically; these are plotting ranges, not extensions of the limits above. The dashed relationship passes the marked 120 °C process-medium / 60 °C ambient point. Use the original diagram to determine the relationship at other temperatures; no numeric endpoint is inferred from the plotted line. For the Y water-hammer arrangement, the 2022 Chinese catalog specifies gas and steam and excludes liquids. Features and Operation Pneumatic pilot control permits operation without an electrical coil on the valve. The catalog describes low starting pressure and control of higher process pressure with lower pilot pressure; this statement does not itself establish an explosion-protection certification. The stainless-steel body and connecting components support corrosion resistance. PTFE sealing is used; verify the complete material list and actual medium compatibility for the application. The 45-degree angle-seat passage and streamlined internal shape reduce flow resistance. The catalog identifies a bronze filter element in the internal assembly to reduce impurity entry. The actuator has a visible position indicator for observing valve opening. The Chinese catalog describes replacing the indicator window with a limit switch or emergency manual device, but does not provide separately orderable accessory codes or a list of included accessories. The actuator control port uses a metal insert. A connection plate can mount a NAMUR solenoid valve; the reviewed pages do not name a specific matching NAMUR valve series or part number. The actuator can rotate through 360 degrees to simplify installation. Flow Direction and Pilot-Pressure Selection For this action code, the catalog shows the process medium entering above the seat, downward from the upper side of the valve piston.
