Proportional Directional Valve 4WRZE10W8-50-7X/6EG24EK31/A1V - Bosch Rexroth R901405882

When return pressure rises inside the manifold, the null position of the pilot stage shifts. This version therefore drains pilot oil separately to the outside while the supply stays internal. Controlled flow is 50 l/min nominal at 315 bar.

Benefits

• 50 l/min nominal flow and 170 l/min maximum flow at 315 bar operating pressure.
• Internal pilot oil supply with external pilot oil drain, keeping pilot pressure independent of main circuit tank pressure.
• Version without a pressure reducing valve in the pilot circuit, rated for 315 bar system pressure.
• FKM seals, HL hydraulic fluid, ±10 V command value through on-board electronics.
• 8.38 kg weight, spool symbol W8, ISO 4401-05-05-0-05 interface.

Applications

Sensible on manifolds with a long shared tank gallery where the return carries pressure. Power units of presses and injection moulding machines are the typical place. 50 l/min covers mid range cylinders in size 10.
