Proportional Directional Valve 4WRLE27V1-600L-4X/VXY/24A1 - Bosch Rexroth R901536841

A replacement valve has to match the controller card in place, otherwise a swap turns into a rebuild. The 4WRLE27V1-600L-4X/VXY/24A1 works from a ±10 V command, meters 600 l/min at 270 bar and is piloted externally through X and Y.

Benefits

• ±10 V command matching widely used controller cards, 24 V DC supply.
• 600 l/min nominal flow at 270 bar, the body carries up to 1850 l/min.
• V1 spool on the ISO 4401-08-08-0-05 interface with four ports.
• External pilot supply through X and external drain through Y, independent of working pressure.
• 20.72 kg with FKM seals, HL hydraulic fluid, three switching positions, CE conformity.

Applications

The valve serves presses, test rigs and large handling axes with high flow demand. Internal piston position feedback gives a repeatable relation between command and opening. Where a current signal is required, a 4...20 mA version exists.
