4WRKE10E100L-3X/6EG24TK31/A5D3M

The 4WRKE10E100L-3X/6EG24TK31/A5D3M is a proportional directional valve manufactured by Bosch Rexroth as part of the 4WRKE Directional Valves series. It meters hydraulic flow and guides actuator movement in closed-loop automation systems. The valve uses a nominal size of 10, establishing mounting dimensions and orifice geometry for medium-frame manifolds. Its porting pattern follows ISO 4401-05-05-0-94 so it can drop into standard CETOP 5 subplates without adapter blocks. A maximum operating pressure of 315 bar on ports P, A, and B allows the unit to work in high-pressure power packs. Mineral oil classified as HL or HLP under DIN 51524 is the required pressure fluid, ensuring seal compatibility and predictable viscosity. An enclosure rating of IP65 protects the onboard electronics against dust and low-pressure water jets. Cleanliness class ISO 4406 20/18/15 defines the filtration level needed to prevent spool wear. The electronics run from a 24 VDC supply, and the internal circuitry can draw up to 72 W under full duty.

The integrated electronics accept a ±10 V command input so a motion controller can proportionally shift the spool, while a matching ±10 V measurement output reports actual position for closed-loop feedback. During operation the amplifier limits supply current to 1.5 A, protecting the coil from overheating. When the pressure drop across the valve is 10 bar it delivers a nominal flow of 100 L/min, giving designers a baseline for sizing cylinders; under favorable conditions the flow may reach 170 L/min, which marks the maximum permissible value before accuracy degrades. Pilot stages consume 4.1 L/min at 315 bar on lines X and Y, information required when calculating pump reserves. Electrical connection is through a plug conforming to DIN EN 175201-804, simplifying wiring in existing panels. Total weight is 8.7 kg, allowing single-person installation while still providing the mass needed for vibration damping.
