Proportional Directional Valve 4WRLE25V1-400P-4X/MXY/24F1 - Bosch Rexroth R901556377

If pilot pressure and drain are already cleanly separated in the system, the 4WRLE25V1-400P-4X/MXY/24F1 fits. It takes pilot oil externally, drains it externally and meters 400 l/min nominal flow in size 25 at up to 350 bar.

Benefits

• External pilot oil supply and external pilot oil return, independent of working and tank pressure.
• 400 l/min nominal flow, maximum flow 1250 l/min.
• Spool symbol V1 in 3 switching positions, linear curve with fine control range.
• 4...20 mA command value on 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals, CE conformity, 19.5 kg.

Applications

The valve is used in power units with a dedicated pilot pump, for example on presses, test rigs and special machinery. A fully separated pilot circuit keeps the step response constant even when working pressure swings widely. Mounting is on a subplate to ISO 4401-08-08-0-05.
