Features

It is a solenoid valve that monitors the direction switch position of the valve and possesses the function of outputting a signal.
It operates the switch directly with the valve operation so reliable output can be obtained.
It does not use magnetic sensors or proximity sensors so the temperature drift and hysteresis are smaller than before.

Specifications

(Note 1) The maximum flow differs depending on the valve format and working pressure.

Working principle

When the spool is in a neutral state, the fixed points of contact and the moving points of contact touch and are in a state of electrical conductance. When the spool begins to operate, the moving points of contact move to the left side in tandem with it, and the fixed points of contact and moving points of contact enter a state of electrical non-conductance.
