• Sandwich plate valve
• Porting pattern according to DIN 24340 form A
• Load compensation in channel P → A or P → B by installed shuttle valve
• 2-way version "P"
• Flow control in case of interaction with proportional directional valve

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

As with all throttle cross-sections, the flow of proportional throttle valves and directional valves depends on the pressure differential Δp.

The effect of a load-compensated, electrical flow control valve results from the combination of throttle valve (measuring throttle) and pressure compensator which keeps the pressure differential Δp at the measurement throttle constant. The pressure differential is determined by the pressure compensator spring and depending on the selected design, it ranges between 8 and 25 bar.

The combination of a proportional directional valve with a pressure compensator results in the effect of a flow control valve for 2 directions. The changing load pressure is to be scanned via a shuttle valve. If pulling loads result during deceleration of mass, counterholding valves are to be provided.
