Total price
When both working pressure and tank back pressure are unsteady, only full separation helps. The 4WRDE16V1-150L-6X/MXY/24A5 feeds its pilot stage through X from a dedicated circuit and drains the pilot oil separately to tank through Y. The main spool with symbol V1 delivers 150 l/min nominal flow under closed loop control by the internal position transducer.
Benefits
- External pilot oil supply and external return separate the pilot stage completely from the main circuit.
- 150 l/min nominal flow with short term peaks of up to 460 l/min.
- Spool symbol V1 with three switching positions up to an operating pressure of 350 bar.
- Closed loop main spool with an analogue ±10 V command value and no separate amplifier.
- Valve weight 10.5 kg on an ISO 4401-07-07-0-05 mounting pattern.
