Datasheet

Note 1) Based on dynamic performance test, JIS B 8374-1981. (Coil temperature: 20°C, at rated voltage,
without surge voltage suppressor)
Note 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)
Note 3) At rated voltage
Note 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).
Caution
Continuous duty type: VT307E
Exclusive use of VT307E is recommended
for continuous duty with long time loading.
Energy-saving type: VT307Y (VT307W)
If low power consumption is required for
electronic control, “VT307Y(W)” (1.8 W) is
recommended.
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.
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 SMC.
2. Energizing solenoid should be done at
least once in 30 days.
Caution
Since this valve has slight air leakage, it can
not be used for vacuum holding (including
positive pressure holding) in the pressure
container.
