The 4WRKE10W6-100L-3X/6EG24TK31/A1D3M directional valve is produced by Bosch Rexroth within the 4WRKE Directional Valves series. It meters hydraulic flow and switches actuator ports in automated machinery. The valve has a nominal size of 10, so its mounting footprint matches middle-frame manifolds. A porting pattern of ISO 4401-05-05-0-94 aligns the body with standardized sub-plates. Pilot oil is supplied externally, which allows stable control even when main line pressure fluctuates, while the drain for the pilot stage is routed internally to reduce external hoses. At a differential pressure of 10 bar the unit passes a nominal flow of 100 L/min, delivering adequate volume for cylinders and motors in general industrial equipment. Working connections p, A, and B tolerate up to 315 bar, enabling operation in high-pressure circuits, whereas the pilot drain channel must not exceed 10 bar to avoid overload of the spool driver. The valve is intended for mineral oil HL or HLP defined by DIN 51524 to maintain sealing compatibility and lubrication.
Electrical control hardware completes the package. A command input range of ±10 V accepts proportional signals from motion controllers, and onboard electronics draw a 24 V DC supply so the driver can be powered from common machine power buses. The maximum supply current is 1.5 A, leading to a peak power consumption of 72 W during full spool deflection. An integrated pressure reducing valve designated ZDR 6 DP0-4X/40YM-W80 stabilizes pilot pressure and improves repeatability. The enclosure carries an IP65 protection rating, permitting installation in wash-down zones provided the connector seal is intact. To avoid premature wear the main flow path requires oil cleanliness of 20/18/15 per ISO 4406(c), which calls for fine filtration in the hydraulic reservoir. For maintenance planning the valve body weighs 8.7 kg, so a single technician can remove it without lifting equipment.
