When one pilot pump feeds several valves, a single common regulation is enough. The 4WRZ10W9-50-7X/6EG24N9K4/M ties into it with external supply and external return, controls 50 l/min nominal flow at 315 bar and weighs 8.24 kg.

Total price
In larger manifolds one pilot pressure pump supplies several proportional valves at once. The 4WRZ10W9-50-7X/6EG24N9K4/M is designed for that, works without a pressure reducing valve of its own and controls 50 l/min nominal flow.
Benefits
- External pilot oil supply and external return, connection to a shared pilot pressure circuit.
- Without a pressure reducing valve in the pilot stage, regulation sits centrally in the circuit.
- 50 l/min nominal flow, up to 170 l/min flow at 315 bar.
- Spool symbol W9 with 3 switching positions across 4 ports in size 10.
- 8.24 kg, 24 VDC, NBR seals, 7-pole plug (6 + PE) to EN 175201-804.

Applications
It is intended for manifolds with several controlled axes and a shared pilot pressure supply. Central regulation saves one reducing valve per valve and unifies the pilot pressure. The middle nominal step suits axes with changing speed.
