Both pilot oil paths run externally here: supply through X, return through Y. That separates the pilot stage completely from the working circuit and keeps it operational during pressure drops or back pressure. Nominal flow is 125 l/min, operating pressure up to 350 bar, mass 9.88 kg.

Total price
If the pilot stage must depend on neither working pressure nor tank pressure, the 4WRGE16V125L-1X/315G24K31/A1M is the right pick. Pilot oil arrives externally through X and leaves through Y, while the valve meters 125 l/min at up to 350 bar.
Benefits
- External pilot oil supply and external pilot oil return decouple the pilot stage from the working circuit
- Pilot pressure stays constant even when working pressure falls below the pilot requirement
- 125 l/min nominal flow in a size 16 body rated at 460 l/min maximum
- Internal spool position feedback for repeatable metering areas
- Analog interface ±10 V, 24 V DC supply, electronics mounted on the valve
- Mass 9.88 kg, NBR seals, mounting pattern ISO 4401-07-07-0-05

Applications
The variant is chosen when a separate pilot power unit exists or when accumulator operation swings the working pressure. It runs in test rigs, simulators and presses with accumulator charging. Because X and Y are routed separately, control behaviour stays identical across the whole load cycle.
