A loaded tank line disturbs the pilot stage. The 4WRZE10E1-50-7X/6EG24EK31/A1D3M therefore takes pilot oil internally from the pressure port but drains it externally through the Y line. With 50 l/min nominal flow, spool symbol E1 and an operating pressure of up to 315 bar it works in the middle range of size 10.
Benefits
- External pilot draining keeps pilot pressure free of back pressure in the return line.
- Internal supply from port P saves the X line.
- 50 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar.
- Command value +/-10 V, on-board electronics with position feedback, 24 VDC.
- Spool symbol E1, subplate mounting to ISO 4401-05-05-0-05, weight 8.48 kg.
- NBR seals, hydraulic fluid HL, UKCA conformity.

Application
This version is used in plants with a long or heavily loaded return line, for instance on presses with several axes working in parallel. Permanent pressure in port P is a precondition. The Y line has to run to the tank without back pressure.
