Functional section

The ZDC... valves are direct operated meter-in pressure compensators of 2 or 3-way design.

They are used for the load compensation as a meter-in pressure compensator in channel P.

These valves basically consist of the housing (1), the control spool(2),compression spring (3) with spring washer(4)and the cover (5)with integrated shuttlevalve (6)

The compression spring (3) holds the control spool (2) in the open position from P1 to P,when the pressure differential P1 to A1 or P1 to B1 is less than 1.0 MPa

If the pressure differential exceeds 1.0 MPa, then the control spool (2)is moved to the left until the pressure differential is restored.
