Proportional Directional Valve 4WRLE25W6-350LJ-4X/MPY/24A1 - Bosch Rexroth R901547437

A suspended load must not drop when the signal stops, which is why spool symbol W6 blocks the actuator ports in mid position. The 4WRLE25W6-350LJ-4X/MPY/24A1 combines that with 350 l/min nominal flow at 350 bar operating pressure.

Benefits

• Spool symbol W6 blocks A and B at centre, so the axis stands still without an extra locking circuit.
• ±10 V command on on-board electronics, the most common interface for analog PLC outputs.
• 350 l/min nominal flow, up to 1250 l/min maximum flow, operating pressure up to 350 bar.
• Internal pilot oil supply with external pilot oil return, so the Y line carries drain oil to tank without back pressure.
• CE conformity, 19.44 kg valve mass on mounting pattern ISO 4401-08-08-0-05.

Applications

Proven on lifting axes and tilting units where the load has to be held at standstill. A voltage command matches standard PLC outputs without a converter card. For plants with long cable runs the 4 ... 20 mA current version is the more rugged alternative.
