Proportional Directional Valve 4WRLE25V1-400L-4X/VXY/24A1 - Bosch Rexroth R901536844

Where system pressure collapses within the cycle, pilot control needs its own supply. This version of the 4WRLE25V1-400L works with external supply and external return and controls 400 l/min nominal flow at up to 350 bar.

Benefits

• External pilot supply and return, fully independent of the state of the main circuit.
• 400 l/min nominal flow, up to 1250 l/min in size 25.
• 350 bar operating pressure with FKM seals, hydraulic fluid HL.
• Spool symbol V1 with internal piston position feedback, on-board electronics.
• Command value plus/minus 10 V, 7-pole connector (6 + PE) to EN 175201-804.
• 19 kg weight, connection diagram ISO 4401-08-08-0-05, CE conformity.

Applications

Typical hosts are presses with unloading circuits, accumulator systems and test benches with strongly varying system pressure. The separate pilot source can be an auxiliary pump or a dedicated accumulator. Mounting is on a subplate to ISO 4401 size 08.
