4WRTE10V50P-4X/6EG24EK31/A1M

The 4WRTE10V50P-4X/6EG24EK31/A1M valve belongs to the 4WRTE Directional Control Valves series manufactured by Bosch Rexroth for closed-loop hydraulic automation. It meters flow by shifting a spool proportionally to command signals and is intended to regulate actuator speed and position. The unit is built to a nominal size of 10, giving it mounting dimensions compatible with medium-flow manifolds. Its porting pattern matches ISO 4401-05-05-0-05, allowing direct stacking on standardized subplates. A maximum operating pressure of 350 bar lets the valve work in high-pressure circuits common in presses and injection machines. The rated flow of 50 l/min at a 5 bar pressure drop per edge defines baseline performance for accurate motion control. A linear fine control range designated as characteristic P ensures predictable flow gain throughout spool travel. Response sensitivity is not greater than 0.05 %, so small command changes translate quickly to flow adjustments, while hysteresis remains within 0.1 %, minimizing position error during reversing strokes. The electromagnet receives 24 V DC and accepts a ±10 V analog interface, linking the valve to typical servo controllers.

Peak application demands are covered by a recommended maximum flow of 170 l/min, which expands the usable range when simultaneous actuator movements occur. Pilot oil is taken internally, reducing external plumbing, while the return line for pilot oil is external to prevent back-pressure from influencing spool stability. An IP65 protection class shields the coils and connector against dust ingress and low-pressure water jets, supporting installation on exposed machinery. Electrical hookup is achieved with a DIN EN 175201-804 plug coded K31, providing a keyed connector that resists vibration loosening. The dynamic parts are sealed with NBR elastomers that withstand common mineral oils used in industrial hydraulics. Maintaining oil at cleanliness class 18/16/13 per ISO 4406 is required to preserve the tight clearances inside the valve and sustain the low hysteresis quoted earlier. Together these characteristics complete the specification package and show how the 4WRTE10V50P-4X/6EG24EK31/A1M integrates into hydraulic systems that demand precise directional control under demanding environmental and flow conditions.
