Proportional Directional Valve 4WRZE10E85-7X/6EG24N9K31/A1M - Bosch Rexroth R901028488

In the 4WRZE10E85-7X/6EG24N9K31/A1M both pilot oil supply and pilot oil return sit outside, while the command value is applied as ±10 V to the on-board electronics. Nominal flow is 85 l/min and pressures up to 315 bar are permitted.

Advantages

• Analog ±10 V command value, 24 V DC supply through an EN 175201-804 connector
• Nominal flow 85 l/min, maximum flow 170 l/min
• External pilot oil supply and external pilot oil return
• Operating pressure to 315 bar, E spool, 3 switching positions
• Concealed auxiliary actuation, built without a pressure reducing valve
• UKCA under SI2016/1091, weight 7.99 kg, NBR seals

Applications

A voltage command paired with a separate pilot feed suits test rigs and forming plants that run their own control oil circuit. At 85 l/min the valve moves larger cylinders in a short time. NBR seals are fitted for HL hydraulic fluid.
