Precautions in use Mounting posture When using the valve of the no spring detent type without excitation, mount the solenoid horizontally so that the detent effect is securely obtained. For the valve of other type, there is no limitation of mounting posture. Switching of solenoid Be sure to deenergize one solenoid before energizing the other solenoid. Tank port Do not connect the tank port to a conduit where surge pressure is generated. Be sure to immerse the end of the tank line piping into oil.
