Proportional Directional Valve 4WRZE10E85-7X/6EG24K31/F1D3M - Bosch Rexroth R901091965

A constant pilot pressure makes the characteristic curve independent of load pressure. In version K of the 4WRZE10E85-7X pilot oil therefore comes in and drains externally, while 85 l/min nominal flow is metered at operating pressure up to 315 bar. The spool carries symbol E.

Benefits

• External pilot oil supply and external pilot oil return
• 85 l/min nominal flow, flow rate up to 170 l/min
• Spool symbol E, four ports, three switching positions
• 4...20 mA current command value, 24 V DC supply
• 8.46 kg weight, operating pressure up to 315 bar, UKCA conformity

Applications

The version is used on power units with a separate pilot pump, for instance in plastics machinery and presses. The dedicated circuit can be filtered separately, which protects the pilot stage. Mounting is on the ISO 4401-05-05-0-05 interface.
