Note 1: The operating pressure differential is the difference between port 1 (high pressure side) and port 2 (low pressure side).
Example: At 0.3 MPa, port 2 is vacuumed (1 Torr or less), while port 1 can be pressurized up to 0.2 MPa (G).
Note 2: The reverse potential pressure indicates the pressure which can be applied from port 2 when port 1 is at atmospheric pressure.
Note 3: Face seal fitting / compression fitting only.
Note 4: Amount of leakage when the ambient temperature is at 20°C and there is 0.1 MPa of differential pressure (gas permeation not included).
Note 5: AC types are all equipped with a full-wave rectifier.
Note 6: Power consumption and apparent power are values at an ambient temperature of 20°C and with rated voltage applied. (Variation range: ±10%)
Note 7: Value at an ambient temperature of 20°C and with rated voltage applied. However, this value depends on the ambient environment.
Note 8: This value is for the grommet type.

| Number | Name | Material |
|---|---|---|
| 1 | Solenoid Coil | Cu + Fe + resin |
| 2 | Fixed Iron Core | Fe |
| 3 | Tube | SUS* |
| 4 | Residual (Seat) | PET* |
| 5 | Movable Armature Iron Core Assembly’ | FKM, SUS, resin (PPS)* |
| 6 | Spring | SUS* |
| 7 | Body | SUS* |
| 8 | O-ring | FKM* |
| 9 | Spacer | Al |
- *Parts in contact with gas
Options Descriptions
(9) Spacer (face seal fitting / compression fitting only): The spacer is used to raise the body when fastening it onto a flat area.
Working Principle
By energizing the solenoid coil (1), the armature movable iron core assembly’ (5) overcomes the composite force, which consists of the force acting on the poppet due to differential pressure and the reactive force of the spring (6), and is suctioned to the fixed iron core (2), thus opening the poppet.
When the energization of the solenoid coil (1) is stopped, the armature movable iron core assembly’ (5) separates from the fixed iron core (2) under the reactive force of the spring (6), thus closing the poppet.
Notes
- *Cannot be used for emergency shut-off valves, etc. The valve described in the catalog is not designed to be used as a safety valve such as an emergency shut-off valve. For such systems, take other measures that will reliably secure safety.
- *Long-term continuous energization will cause the solenoid coil to generate heat. Avoid use in airtight containers. Install in locations with good ventilation. Do not touch the solenoid valve during or immediately after energization.
- *Refer to the manufacturer's catalog for product information not detailed above.
