Note 1) When used as a selector valve (pressurising ports 1, 3), the pressure should be within the range of port 1 pressure
Note 2) Impact resistance: No malfunction resulted in an impact test using a drop impact tester. The test was performed one time each in the axial and right angle
directions of the main valve and armature, for both energised and de-energised states. (Value in the initial stage)
Vibration resistance: No malfunction resulted in 8.3 to 2000 Hz, a one-sweep test performed in the axial and right angle directions of the main valve and
armature for both energised and de-energised states. (Value in the initial stage)
Note 3) Vibration resistance is 50 m/s
