Photos are for reference only. Not all models have pictures.

Description

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.

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.

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.

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.

Operation and Maintenance

  • Verify the actual operating conditions against the catalog limits before use.
  • 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.
