The 4WRKE35E1000L-3X/6EG24K31/A1D3M-280 directional valve is manufactured by Bosch Rexroth for the 4WRKE Directional Valves series. It meters hydraulic flow to actuators in closed-loop automation where proportional control is required. The valve is built in nominal size 35, allowing a nominal flow of 1000 L/min for standard motion tasks, while a main stage flow rating of 3000 L/min supports transient peak demands. A maximum operating pressure of 350 bar lets the unit handle high-pressure circuits common in presses and plastic machinery. The integrated electronics run on a 24 VDC supply, accept a ±10 V command or feedback signal, and draw up to 1.5 A of current so drive cards can be sized accordingly. Electrical power consumption is limited to 72 W to keep enclosure heat generation moderate.
Control accuracy is aided by a response sensitivity not exceeding 0.5 %, and steady-state hysteresis remains within 1 %, supporting repeatable spool positioning. The housing carries an IP65 ingress rating, permitting installation in areas exposed to fluid spray when a matched connector is fitted to the DIN EN 175201-804 interface. Mounting conforms to the ISO 4401-10-08-0-94 porting pattern, simplifying manifold design. Pilot oil can be supplied internally or drained externally, giving flexibility for backpressure management. NBR seals are installed to resist standard mineral oils, and the complete assembly weighs 34 kg, which influences lifting requirements during maintenance.
