Proportional Directional Valve 4WRZE25E325-7X/6EG24K31/A1V - Bosch Rexroth R900962775

Fully separated pilot paths make the 4WRZE25E325-7X/6EG24K31/A1V independent of pressure behaviour and back pressure in the working circuit. The pilot stage is fed through X and relieved through Y, while the main spool with symbol E meters 325 l/min nominal flow and up to 870 l/min at peak.

Benefits

• External pilot oil supply and external return decouple the pilot stage completely.
• 325 l/min nominal flow with a maximum flow rate of 870 l/min at 350 bar.
• Spool symbol E with three switching positions and internal closed loop position control.
• Pilot stage without a pressure reducing valve, supply voltage 24 VDC.
• FKM seals, a valve weight of 20.1 kg and connection diagram ISO 4401-08-08-0-05.

Application

The variant belongs on axes with their own pilot pump or accumulator supply, for example in rolling mills and large test rigs. Mineral oil HL is intended. Conformity is documented as UKCA for electromagnetic compatibility.
