Proportional Directional Valve 4WRLE25V400L-4X/MXY/24C6 - Bosch Rexroth R901568615

Once a cylinder in rapid traverse demands more oil than a normal directional valve will pass, the flow figure becomes the selection criterion. This size 25 valve passes up to 1250 l/min, meters at 400 l/min nominal flow and holds spool position through internal position feedback.

Benefits

• Flow up to 1250 l/min through the valve, nominal flow 400 l/min.
• Internal spool position feedback keeps spool travel tied to the command value.
• External pilot oil supply and external return, independent of the working circuit up to 350 bar.
• ±10 mA command value at the on-board electronics, 24 VDC supply.
• Spool symbol V, 4 ports, 3 switching positions, ISO 4401-08-08-0-05, weight 19.36 kg.
• NBR seals for HL hydraulic fluid, CE conformity.

Applications

The valve is built for large presses, forging lines and water engineering hydraulics with very large cylinder areas. The external pilot circuit is fed from an auxiliary pump or an accumulator. At 19.36 kg the valve can still be mounted by hand despite its flow class.
