4WRZ10W6-50-7X/6EG24N9ETK4/V

The 4WRZ10W6-50-7X/6EG24N9ETK4/V proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth. It meters hydraulic flow and directs pressure lines in automation circuits that require smooth, electrically controlled spool positioning. The nominal flow of 50 l/min at a differential pressure of 10 bar defines the capacity the main stage can pass while maintaining accurate control. A maximum operating pressure of 315 bar lets the valve handle high-pressure supply manifolds common in industrial presses and mobile drives. The mounting pattern ISO 4401-05-05-0-94 matches standard subplates so the unit can replace or upgrade existing hardware without manifold rework. Cleanliness class ISO 4406 20/18/15 sets the solid contamination level that must be maintained to protect the precision spool assembly. Internal pilot oil supply removes the need for an external pilot line, and the internal pilot oil drain limits plumbing complexity. A continuous 100 percent duty cycle permits uninterrupted solenoid actuation, and an overall weight of 7.8 kg supports rigid installation on mid-size manifolds.

Electrical connection is made through a DIN EN 175301-803 plug, giving a widely adopted interface for quick coil replacement in the field. The coil enclosure carries an IP65 rating, which blocks dust ingress and water jets during routine wash-down. Windings withstand temperatures up to 150 °C, enabling reliable operation when the manifold is mounted near hot hydraulic reservoirs. The drive electronics may deliver up to 1.5 A, a value chosen to produce full magnetic force without overheating the coil. Cold solenoid resistance of 4.8 Ω and a maximum hot resistance of 7.2 Ω provide predictable current draw across the temperature range for closed-loop current controllers. FKM seals are fitted, ensuring compatibility with most mineral and synthetic hydraulic fluids while maintaining low leakage. The internal drain path is rated for 30 bar at port T, permitting back-pressure without affecting pilot stability. These electrical and sealing characteristics complement the hydraulic ratings given earlier and complete the valve’s technical profile.
