Proportional Directional Valve 4WRKE25E1-220L-3X/6EG24K31/A1D3M - Bosch Rexroth R901001641

When pilot pressure and pilot return both come from outside, the main stage is fully decoupled from the working circuit. That is how the 4WRKE25E1-220L-3X works in version K, where a ±10 V command value meters 220 l/min nominal flow at up to 350 bar operating pressure.

Benefits

• External pilot oil supply and external pilot oil return, pilot stage independent of the working circuit
• 220 l/min nominal flow, flow rate up to 870 l/min
• ±10 V command value, 24 V DC supply, 7-pole connector (6 + PE)
• Spool symbol E1, four ports, three switching positions
• 17.84 kg weight, NBR seals, HL hydraulic fluid

Applications

This version is needed on machines whose system pressure drops close to zero during the cycle, for example in unloading circuits. The pilot stage stays supplied by its own pump and the valve keeps working. It mounts on a subplate to ISO 4401-08-08-0-05.
