Proportional Directional Valve 4WRZ25E1-325-7X/6EG24N9EK4/D3V - Bosch Rexroth R900956738
High throughput builds back pressure in the return line. The 4WRZ25E1-325 therefore drains pilot oil externally while the supply stays internal. Nominal flow 325 l/min, spool symbol E1, weight 20.46 kg.

Description
At high throughput the return line builds back pressure that acts on the pilot stage. The 4WRZ25E1-325-7X/6EG24N9EK4/D3V therefore drains pilot oil externally and keeps supplying the pilot stage internally.
Benefits
- Internal pilot oil supply, external return, independent of back pressure in the tank circuit
- Nominal flow 325 l/min, maximum flow 870 l/min
- Pressure reducing valve in the pilot stage, spool symbol E1
- Pilot-operated spool valve with concealed auxiliary actuation
- Maximum operating pressure 350 bar, FKM seals, weight 20.46 kg
Applications
Intended for high flow axes on plants with a return filter or cooler in the manifold. Separate draining keeps the pilot circuit free of counter pressure. 24 VDC supply, HL hydraulic fluid.
