Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9K31/F1M - Bosch Rexroth R901302127

The 4WRZE10W6-85-7X/6EG24N9K31/F1M is the 85 l/min variant with a W6 spool. Pilot oil is supplied and returned externally, no pressure reducing valve is fitted, and operating pressure reaches 315 bar.

Advantages

• Nominal flow 85 l/min, maximum flow 170 l/min
• Operating pressure to 315 bar at a valve weight of 8 kg
• External pilot oil supply and external pilot oil return for a separate pilot circuit
• W6 spool, 3 switching positions, subplate mounting to ISO 4401-05-05-0-05
• Concealed auxiliary actuation, built without a pressure reducing valve
• On-board electronics, 4 to 20 mA command value, 24 V DC, UKCA under SI2016/1091

Applications

The larger rating fits cylinders in presses, lift tables and test rigs that take in a lot of oil in a short time. A separately fed pilot circuit keeps the pilot stage steady even when main circuit pressure swings. NBR seals are rated for HL hydraulic fluid.
