At 315 bar operating pressure large forces act on a small spool area. The 4WRZ10W8-85-7X/6EG24N9K4/D3M handles that pressure in size 10 while controlling an 85 l/min nominal flow. External pilot circuit, 8.24 kg, up to 170 l/min of flow.

Total price
High pressure and large flow together put demands on the pilot stage. The 4WRZ10W8-85-7X/6EG24N9K4/D3M works at 315 bar with an 85 l/min nominal flow and draws its pilot oil from a dedicated circuit.
Benefits
- 315 bar operating pressure at 85 l/min nominal flow, up to 170 l/min flow.
- External pilot oil supply and external return, a dedicated pilot circuit.
- Spool symbol W8, 3 switching positions across 4 ports in size 10.
- Pressure reducing valve in the pilot stage and concealed auxiliary actuation.
- 8.24 kg, 24 VDC, NBR seals for HL hydraulic fluid, interface ISO 4401-05-05-0-05.

Applications
The valve is wanted on presses and clamping systems working at the top of the pressure range. The dedicated pilot circuit gives the same switching times regardless of load pressure. The large nominal step keeps throttling losses low at high flow.
