Proportional Directional Valve 4WRZE10E50-7X/6EG24N9K31/F1M - Bosch Rexroth R901225527

The 4WRZE10E50-7X/6EG24N9K31/F1M separates the pilot stage entirely from the main circuit, with pilot oil supply and return both routed outside. Nominal flow is 50 l/min, operating pressure reaches 315 bar and the valve weighs 8.7 kg.

Advantages

• External pilot oil supply and external pilot oil return, independent of main pressure
• Nominal flow 50 l/min against a maximum flow of 170 l/min
• Operating pressure to 315 bar, E spool, 3 switching positions
• Concealed auxiliary actuation, built without a pressure reducing valve
• 4 to 20 mA command value, 24 V DC supply, 7-pole connector (6 + PE) to EN 175201-804
• UKCA conformity for electromagnetic compatibility SI2016/1091

Applications

The variant makes sense in plants with their own pilot pump or accumulator feed, such as test rigs and large power units. Even when system pressure swings, the pilot stage stays at a constant level. NBR seals cover HL hydraulic fluid.
