The 4WRKE25W000L-3X/6EG24EK31/A5D3M-435 valve belongs to the 4WRKE Directional Valves series from Bosch Rexroth and is intended to shift hydraulic flow paths in automated machinery. It is manufactured for manifolds with nominal size 25, allowing direct mounting on a subplate that follows the ISO 4401-08-07-0-94 porting pattern. A maximum operating pressure of 350 bar lets the spool manage high-pressure circuits, while the valve body channels up to 870 L/min without exceeding its rated flow limit. Internal pilot oil supply eliminates the need for an external feed line, and an external pilot oil drain directs return flow straight to tank. Actuation is handled by a 6E solenoid with a removable coil, energized from a 24 V DC source; the coil draws up to 1.5 A and dissipates no more than 72 W during continuous duty. Together, these characteristics make the valve fit for large-capacity presses, molding machines, and other installations requiring fast directional changes under load.
The unit accepts a ±10 V command value input so the control system can position the spool proportionally, and it returns a ±10 V measurement output for real-time monitoring of spool travel. Electrical connection is made through a DIN EN 175201-804 plug, simplifying wiring in standard control cabinets. An IP65 ingress protection rating shields the enclosure from dust and low-pressure water jets, enabling reliable service on the factory floor. All dynamic seals are NBR to suit common mineral-oil hydraulics and to maintain leakage control over a broad temperature range. The assembled valve weighs 16.8 kg, a mass that balances structural rigidity with ease of handling during installation or service. These electrical, environmental, and material features complement the high-pressure hydraulics described earlier and ensure consistent performance in closed-loop motion platforms.
