Description of function

With the solenoid coil de-energised, a connection is provided from the consumer port (A) to the return line into the tank (T) via the conical seat in the valve insert (V). Here the low pressure (P) applied is blocked by the spherical seat in the valve insert (V). When the corresponding solenoid coil for a given function is actuated, the plunger opens the ball in the valve insert (V) and closes the conical seat to the return line (T). The low pressure (P) is thus applied to the hydraulic cylinder via the consumer port (A). Note: In case of emergency operation, screw (S) must be screwed in up to the stop to make the conical seat in the valve insert (V) close the return line to the tank (T) tightly.
