Proportional Directional Valve 4WRZE25E325-7X/6EG24N9K31/A1V - Bosch Rexroth R900967051

The valve spreads up to 325 l/min across four ports with electrical spool position feedback, at 350 bar operating pressure and an 870 l/min flow limit. Pilot oil is fed in from outside, drained outside, so the pilot circuit works independently.

Benefits

• 325 l/min nominal flow, 870 l/min flow limit at 350 bar operating pressure
• Pilot oil supplied externally, drained externally, steady pilot pressure
• Spool symbol E with 3 switching positions across 4 ports
• Analog command plus to minus 10 V, on-board electronics, 24 VDC supply
• FKM seals for HL fluid, UKCA to SI2016/1091, mass 20.3 kg

Applications

Rolling mills, continuous casting plants as well as large hydraulic centres already run a dedicated pilot circuit, which this variant uses directly. Pilot pressure then stays stable through load changes. The standard ISO 4401-08-08-0-05 pattern allows a straight swap.

Manufacturer

Bosch Rexroth lists the valve as R900967051. Performance limits, curves plus mounting position notes appear in data sheet RE 29115.
