This version draws pilot oil from a separate source and returns it internally to tank - useful where main pressure swings hard. It meters 50 l/min nominal flow up to 315 bar, weighs 9.1 kg and takes its setpoint as 4...20 mA.

When system pressure pulses in step with the machine, piloting suffers too. The 4WRZE10W8-50-7X/6EG24N9TK31/F1D3V therefore draws pilot oil externally and drains it internally, at 50 l/min nominal flow and 315 bar operating pressure.
Benefits
- External pilot supply with internal return - steady pilot pressure without a second return line.
- 50 l/min nominal flow, 170 l/min maximum throughput in size 10.
- 4...20 mA setpoint, resistant to interference picked up in cable ducts.
- Spool symbol W8, 3 switching positions, 4 ports, ISO 4401-05-05-0-05 pattern.
- Mass 9.1 kg, FKM seals, operation on HL hydraulic fluid.

Applications
Fits installations whose working pressure pulsates heavily, such as forming presses or hydraulic hammers, where axis control still has to stay even. Internal draining saves one line as long as tank pressure remains low.
