Product description

Valves of type ZDC are direct operated supply pressure compensators in 2- or 3-way version.

The are used for the load compensation as supply pressure compensator in channel P.

These valves basically consist of the housing (1), the control spool (2), compression spring (3) with spring plate (4) and the cover (5) with installed shuttle valve (6).

The compression spring (3) holds the control spool (2) in the opened position from P2 to P1 if the pressure differential P1 → A1 or P1 → B1 is smaller than 10 bar.

If the pressure differential exceeds 10 bar, the control spool (2) is moved to the left until the pressure differential is restored again.

In connection with the supply pressure compensator, the pilot-operated proportional directional valve is to be used with “external pilot oil supply“!

With external pilot oil supply, the connection to channel P is blocked. The pilot oil is sampled from a separate control circuit.

With internal pilot oil supply, the connection to channel P is open. The pilot oil is sampled upstream the throttle side of the pressure compensator (port X in the subplate is blocked).
