Proportional Directional Valve 4WRZ10W8-85-7X/6EG24N9K4/D3M - Bosch Rexroth R900246980

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.
