When pilot oil comes from a circuit of its own, piloting stays independent of load pressure. The 4WRZ10W8-85-7X/6EG24N9K4/V uses an external supply and an external return for that and controls 85 l/min nominal flow to symbol W8 at up to 315 bar.

Application
When load pressure collapses during the cycle, a dedicated pilot circuit keeps valve dynamics steady. Such circuits are found in presses, roll adjustment drives and test equipment. The command value comes from external amplifier electronics.
