Product Description
VT317 3-port poppet type solenoid valve is often used in applications where precise control of fluid flow is required.
1. Compact valve body design provides high flow rates.
2. The poppet and seat design can provide a very effective seal, reducing leaks and improving efficiency.
3. Suitable for use in vacuum and pneumatic applications.
4. A single valve with 6 valve functions.
5. Selective porting can provide 6 valve functions, such as N.C. valve, N.O. valve, Divider valve, Selector valve etc.

*2) Impact resistance: No malfunction occurred when it is tested with a drop tester in the axial direction and at the right angles to the main valve and armature in both energized and de-energized states every once for each condition. (Values at the initial period)
Vibration resistance: No malfunction occurred in a one-sweep test between 45 and 1000 Hz. Test was performed at both energized and de-energized states in the axial direction and at the right angles to the main valve and armature. (Values at the initial period)
*3) At rated voltage.

Continuous duty type: VT317E
Exclusive use of VT317E is recommended for continuous duty with long time loading.
▲ Caution
1. This model is for continuous duty, not for high cycle rates. But even in low cycle rates, if energizing the valve more than once a day, please consult with VPC.
2. Energizing solenoid should be done at least once in 30 days.
Vacuum spec. type: VT317V
This vacuum model has less air leakage than the standard model under low pressure. It is recommended for vacuum application.
▲ Caution
1. Since this valve has slight air leakage, it can not be used for vacuum holding (including positive pressure holding) in the pressure container.
Specifications different from standard are as follows.
| Operating pressure range | -101.2 kPa to 0.1 MPa |
