A pilot circuit with its own pressure reducing valve keeps control pressures steady even as working pressure climbs to 350 bar. The 4WRZE16E180-7X/6EG24N9ETK31/A1D3V meters 180 l/min in size 16 that way, with spool symbol E on a ±10 V command value.

Total price
In plants without a separate pilot pump the valve has to limit pilot pressure itself. This pilot-operated size 16 model carries a pressure reducing valve for that, supplies itself internally, returns internally and meters 180 l/min at operating pressure up to 350 bar.
Benefits
- Built-in pressure reducing valve in the pilot circuit caps control pressure despite 350 bar working pressure.
- 180 l/min nominal flow against a range maximum flow of 460 l/min.
- Concealed manual override lets the axis be moved while control power is missing.
- ±10 V command value at the on-board electronics, 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
- FKM seals, mass 12.12 kg, mounting pattern ISO 4401-07-07-0-05, conformity UKCA.

Applications
The valve is fitted in presses, lifting gear and forming plants on a size 16 interface. Symbol E across 3 switching positions sets the mid position. Internal pilot routing needs a tank port with low back pressure, then the axis works over the full range up to 350 bar.
