Product Description
1. Low power consumption
DC4 W (Standard type), DC1.8 W (Energy-saving type)
No lubrication required. Possible to use in vacuum or under low pressures
2. External pilot
Vacuum: Up to –101.2 kPa, Low pressure: 0 to 0.2 MPa
3. Changeable actuation: N.C., N.O., or external pilot
4. Can be used as a selector or divider valve (External pilot)
* Use external pilot type in the following cases:
1)For vacuum or for low pressure 0.2 MPa or less.
2)When having P port downsized in diameter.

*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)

Product Dimensions
When changing the passage state, confirm that pressure has been removed from the valve. Unscrew the M4 x 0.7 hexagon socket head cap screw in the changeover plate and match the◀mark on the adapter plate with the character on the changeover plate. Piping is as follows.

*1) In the case of internal pilot, confirm that a plug is inserted to X port. If not, insert a R 1/8 plug.
*2) In the case of external pilot, supply air pressure from X port.
Confirm the safety sufficiently and conduct carefully when changing the passage state or restarting after changes.
