When the pilot circuit is fed from main pressure, the valve has to limit pilot pressure itself. The 4WRZ32W8-360 carries a pressure reducing valve for that and controls 360 l/min nominal flow at up to 350 bar. Spool symbol W8, NBR seals, 43.6 kg.

A forming axis without a separate control oil pump needs a valve that supplies and protects its own pilot stage. The 4WRZ32W8-360-7X/6EG24EK4/D3M takes pilot oil internally, returns it externally and handles 360 l/min nominal flow at up to 350 bar.
Advantages
- 360 l/min nominal flow in size 32, interface ISO 4401-10-09-0-05 rated up to 1600 l/min
- Pressure reducing valve fitted in the pilot stage, internal pilot oil supply with external return
- Maximum operating pressure 350 bar, three switching positions with spool symbol W8
- NBR seals for hydraulic fluid HL
- 24 VDC, electrical with external electronics, connector 7-pole (6 + PE) according to EN 175201-804
- 43.6 kg weight

Applications
The valve fits presses and roll drives where a large cylinder area is moved under control. The external pilot oil return keeps the pilot stage clear of back pressure in the tank line. Signal processing calls for a separate amplifier, the output stage is not mounted on the valve.
