Proportional Directional Valve 4WRZE25E325-7X/6EG24N9TK31/A1M - Bosch Rexroth R901313534

A crowded tank gallery pushes back and degrades the pilot stage. The 4WRZE25E325-7X/6EG24N9TK31/A1M therefore drains its pilot oil separately to tank and meters an undisturbed 325 l/min nominal flow at 350 bar operating pressure.

Benefits

• External pilot oil drain decouples the pilot stage from pressure in the return line.
• 325 l/min nominal flow, peaking at 870 l/min.
• A ±10 V command value at the on-board electronics, fed from an analogue card without a converter.
• Spool symbol E, three switching positions, four ports, ISO 4401-08-08-0-05 mounting pattern.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 20.16 kg valve mass.

Application

Intended for manifolds with many consumers where the shared return line carries pressure. The extra line for the pilot oil drain has to be provided during assembly. Typical applications are presses and hydraulic test rigs.
