Proportional Directional Valve 4WRKE32W8-400L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901121949

Filters and coolers in the tank line build back pressure that detunes the pilot stage. This version of the 4WRKE32W8-400L takes pilot oil internally but discharges it through a dedicated Y line, at 400 l/min nominal flow with a current command.

Benefits

• Internal supply, external pilot return, independent of back pressure in the tank line.
• Command value 4 to 20 mA into on-board electronics, 24 V DC supply.
• 400 l/min nominal flow, up to 1550 l/min in size 32.
• Spool symbol W8, linear characteristic curve, with internal piston position feedback.
• 350 bar operating pressure, NBR seals, hydraulic fluid HL.
• 37.3 kg weight, connection diagram ISO 4401-10-09-0-05.

Applications

The variant belongs in systems with a return filter, an oil cooler or a long tank line, for instance large forming presses. The Y line runs straight to tank without a restrictor. Installation otherwise matches the internally returned version.
