Model Code Explained

Code Meaning for this model
2W 2W series 2/2-way fluid-control valve; normally closed.
(blank pressure code) Standard option.
030 030 size series; the pressure-condition code determines its orifice and flow data.
08 1/4 in port size; selected thread: PT1/4.
A Coil supply: 220 V AC.
(blank entry code) Terminal electrical entry.
(blank thread suffix) PT thread standard.

Technical Specifications - 2W

The following values are from 2W PDF page 1 and describe the listed configuration. Pressure differential is the inlet-to-outlet pressure difference; proof pressure is a separate test value.

Parameter Details
Valve function 2/2-way: two ports and two operating positions
Actuation Direct acting
Initial state Normally closed
Media Air, water and oil
Body material Brass
Standard seal material FPM-F; contact the supplier if another seal material is required
Viscosity limit Below 20 cSt
Port thread PT1/4
Orifice diameter 3 mm
Flow coefficient Cv 0.33
Effective area / section 6 mm²
Pressure differential 1 MPa maximum operating pressure differential
Proof pressure 5.0 MPa
Catalog reference weight 295 g
Water temperature 1 to 80°C
Air temperature -20 to 90°C; the catalog specifies an air dew point of -20°C or lower
Oil temperature -10 to 80°C; the catalog footnote states 50 cSt or less at the lower-temperature condition
Ambient temperature -20 to 70°C

The catalog weight is the terminal-entry reference. It is a reference value, not a recorded weighing of this individual item.

The general viscosity limit and the lower-temperature oil footnote are retained as separate catalog statements. Check the actual medium and temperature against both before selection.

Electrical Specifications

Parameter Details
Coil designation for this entry CDA116
Rated voltage 220 V AC
Voltage tolerance ±15% for AC
Electrical entry Terminal
Protection class IP65
50 Hz power consumption 10 VA
60 Hz power consumption 8 VA
Temperature rise at 50 Hz 35°C
Temperature rise at 60 Hz 30°C
Insulation class Class B

Coil temperature rise is distinct from the ambient and fluid-temperature limits. The power figures are the values tabulated for the selected AC or DC supply.

Features and Operation

  • This 2/2-way valve is normally closed when not energized. The 030 and 050 branches use direct-acting construction.
  • The compact brass body is intended for air, water and oil within the catalog limits. The catalog describes rapid response, easy installation and dismantling.
  • Terminal and grommet electrical entries are separate order-code choices. The grommet option includes the catalog-specified 0.5 m wire.
  • The illustrated mounting bracket is optional. It is not included merely because it appears in a dimensional drawing.

External and Mounting Dimensions

These are the terminal-entry drawing values in the 2W PDF, page 2. Each letter below refers to its own dimension line; do not combine unrelated spans into an assumed overall length × width × height.

Drawing letter Dimension / specification
A 72.5 mm
AB 40 mm
B 29.5 mm
C 71 mm
D 20 mm
E 49 mm
F 43.5 mm
G 10 mm
K 5.3 mm
KA 40 mm
P PT1/4
PA 10 mm
Q M5
QA 16 mm

The drawing marks two holes as 2-ØK (K = 5.3 mm), two threaded locations as 2-Q (Q = M5), and the bracket as optional. P is the valve port thread. Use the original views to locate QA, KA and the bracket outline; a listed hole diameter alone does not prove interchangeability.

For detailed product dimensions and mounting drawings, please download and refer to the PDF catalog.

Flow and Performance Reference

Parameter Details
Air chart vertical axis Downstream pressure P2, 0-1.0 MPa; curves identify upstream pressure P1 and sonic / subsonic regions
Air chart flow axis Orifice Ø3 mm: Q in L/min (ANR); marked values 100-600, in steps of 100
Water chart vertical axis Flow Q in L/min, logarithmic scale; visible reference labels from 0.1 to 50
Water chart horizontal axis Pressure differential ΔP = P1 - P2, in MPa; visible labels 0.001-0.6

The original flow charts are on 2W PDF page 2. Chart axes are reading scales, not guaranteed flow ratings. Use the curve for the correct orifice and medium; do not substitute a value estimated from a graph for a tabulated Cv or effective area.

Internal Components - Catalog Reference

The following numbered key is the catalog illustration for 2W030 (terminal), on PDF page 1. It is a drawing reference, not an included-parts quantity list or a list of independent ordering codes. Other size and entry versions must be checked against their own assembly.

Drawing number Component
1 Body
2 Airtight ring
3 Spring
4 Fixed cap
5 O-ring
6 Fixed plate
7 Movable core
8 Coil assembly
9 E-clip
10 Gasket
11 Connector
12 Washer
13 Screw
14 Filter

Catalog note: the extra-large-flow T type has no filter element. The filter shown in the reference key must not be interpreted as included in a T configuration.

Mounting Accessory Reference

The 2W catalog directs accessory orders to the 2S accessory ordering information (printed page 194). That shared ordering table identifies F-2S030LB for this size.

The bracket is optional. The supplied catalog does not tabulate a separate bracket weight or a package-component count. Select the bracket for the actual valve family and drawing; legacy and new bracket compatibility must not be inferred from a similar listing name.

Series Ordering Options

These are alternative series choices, not additional configurations included with this order. The Model Code Explained table above states the actual selection.
