The hydraulic circuit shows how two hydraulic cylinders work independently. It uses 4/3 All-closed-center position directional control valves as the final control elements.

The power supply unit includes a fixed-displacement pump that delivers pressurized fluid to the circuit with constant displacement. A pressure relief valve (PRV) can be used to set the highest operating pressure (say 200 bar).

The circuit with all-closed-center position 4/3-DC valves can control the cylinders independently. The pump flow rate capacity must be enough for simultaneous operation of the cylinders if required.
