Product Feature
Series VT 3 port, direct operated poppet valves are compact in size, yet provide large flow capacity, and low power consumption. The series is suitable for use in vacuum applications. The VT valve is a single valve with 6 functions (universal porting type) such as N.C. valve, N.O. valve, divider valve, selector valve, etc. The manifold style valve, series VO, can be easily converted from N.C. (normally closed) to N.O. (normally open) by merely turning over the switch cover.

* Semi-standard.
*1) Based on dynamic performance test, JIS B 8419: 2010. (Coil temperature: 20°C, at rated voltage, without surge voltage suppressor)
*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.
*4) The value is different for continuous duty type (VT307E), and energy-saving type (VT307Y/W). Refer to "Valve Options" shown below. Make sure that dust and/or other foreign materials do not enter the valve from the unused port (e.g. exhaust port).

Valve Options
Continuous duty type: VT307E
Exclusive use of VT307E 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.
Specifications different from standard are as follows.
| Apparent power/AC | Inrush | 7.9 VA (50 Hz), 6.2 VA (60 Hz) |
| Holding | 5.8 VA (50 Hz), 3.5 VA (60 Hz) | |
| Power consumption/DC | 1.8 W, With indicator light: 2 W | |
| Response time* | 30 ms or less (at 0.5 MPa) | |
*Please refer to the standard "Specifications" on page 2 *1.
Energy-saving type: VT307Y (VT307W)
If low power consumption is required for electronic control, "VT307Y(W)" (1.8 W) is recommended. Specifications different from standard are as follows.
| Power consumption/DC | 1.8 W, With indicator light: 2 W |
| Response time* | 25 ms or less (at 0.5 MPa) |
* Please refer to the standard "Specifications" on page 2 *1.
Vacuum spec. type: VT307V (VT307W)
This vacuum model has less air leakage than the standard model under low pressure. It is recommended for vacuum application.
Caution:
Since this valve has slight air leakage, it can not be used for vacuum holding (including positive pressure holding) in the pressure container.
