The 4WRKE32W6-600L-3X/6EG24TK31/A5D3M directional valve is manufactured by Bosch Rexroth for the 4WRKE Directional Valves series. It regulates actuator speed and direction in hydraulic automation circuits. A nominal size of 32 provides passage geometry large enough for systems requiring significant flow, while the ISO 4401-10-08-0-94 mounting pattern lets the valve seat directly on standardized subplates. The electronics accept a ±10 V command value input so motion controllers can issue proportional spool positions, and the 24 V DC supply voltage powers the amplifier section with a maximum draw of 72 W. Connection to the machine harness is made through a DIN EN 175201-804 plug, supporting fast replacement during service. Under a differential pressure of 10 bar the valve passes a nominal flow of 600 L/min, and it can reach 1600 L/min when ports are fully open, accommodating high-demand cycles. Hysteresis is kept to ≤1 %, minimizing position error during repeated shifts and improving closed-loop accuracy.
For pressure management the unit tolerates 350 bar on ports P, A, and B, enabling operation in heavy-duty presses and molding equipment. The pilot stage is supplied with oil at up to 315 bar, and its internal pilot drain must stay below 10 bar to maintain stable spool centering. A pilot oil flow of 13.0 L/min ensures the control stage moves quickly without cavitation. The integrated pressure reducing valve type ZDR 6 DP0-4X/40YM-W80 limits pilot pressure independently of the main circuit so command signals remain linear even when system pressure fluctuates. An enclosure rating of IP65 protects the electronics against dust ingress and water jets, permitting installation on machinery exposed to wash-down or coolant spray. The housing weighs 31.5 kg, so standard manifold blocks can support it without additional bracing.
