The 4WRKE27E500L-3X/6EG24EK31/A1D3M directional valve is part of the 4WRKE Directional Valves series from Bosch Rexroth, designed to meter hydraulic flow in closed-loop motion systems. Command and actual signals are exchanged through a ±10 V interface, and the integrated electronics require a 24 V DC supply while drawing up to 1.5 A. Peak electrical demand is 72 W. The main stage handles up to 1000 L/min and tolerates 210 bar on the pressure and work ports, enabling high-capacity circuits. Installation aligns with the ISO 4401-08-07-0-94 pattern, so it fits common size 08 manifolds without adapters.
At a 10 bar differential the valve delivers a nominal 500 L/min, with internal pilot oil supply ensuring control pressure and an external pilot drain returning fluid to tank. Reliable operation is maintained when ambient temperatures remain below 50 °C and pressure fluid stays under 80 °C. The enclosure carries an IP65 rating to resist dust and water jets, and main stage cleanliness is specified at class 20/18/15 to protect precision orifices. NBR seals isolate the hydraulic fluid, and the assembled unit weighs 17 kg for manageable handling during service.
