Proportional Directional Valve 4WRZE25E325-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R900953731

Where long cable runs meet tight installation space, this combination fits. Pilot oil is routed entirely internally and the command value travels as a 4-20 mA current, at 325 l/min nominal flow with spool symbol E.

Benefits

• Fully internal pilot circuit, so neither an X nor a Y port is required on the manifold
• Command value 4-20 mA, immune to voltage drop and pick-up on long cables
• 325 l/min nominal flow, valve maximum 870 l/min, operating pressure up to 350 bar
• Spool symbol E, three switching positions, four ports
• Mass 20.52 kg, FKM seals, HL hydraulic fluid

Technical data

Application

This version is asked for on widely distributed plant such as locks, lift bridges and crane installations, where the control cabinet stands tens of metres away from the valve. The internal pilot circuit keeps piping at the power unit simple. Low tank pressure in the main circuit remains a precondition.

Manufacturer

Bosch Rexroth lists the valve under material number R900953731. Step response, characteristic curves and installation dimensions follow data sheet RE 29115, plus RE 07600-B.
