The 4WRREH6VB15P-1X/G24K0/B5M valve is part of the 4WRE Proportional Directional Valves series produced by Bosch Rexroth for hydraulic automation tasks that require precise flow control. It accepts a 24 V DC supply voltage to energize its solenoid and reacts to a ±10 V setpoint input so that a motion controller can issue proportional commands. An input resistance of 100 kΩ minimizes loading on the control electronics, while overall power consumption stays at 30 VA. The internal spool is arranged in a 4/3-way layout, allowing controlled movement of actuators in both directions and a centered neutral position. A nominal flow of 15 l/min at a 70 bar pressure drop defines the sizing for cylinders and motors connected to the valve. Fast response is supported by a 5 ms 0–100 % step time, and hysteresis remains within 0.2 % to keep position repeatability high during small signal reversals.
The hydraulic stage shows a curve kink in the pressure-flow characteristic at 60 %, signaling the point where the slope changes for finer metering at low commands. Continuous service is possible because the duty cycle is specified at 100 %. Maximum working pressure on ports p, a, and b reaches 315 bar, while the tank port tolerates up to 100 bar. Subplate mounting makes removal straightforward, and the porting pattern follows ISO 4401-03-02-0-94 so it mates with common size 03 bases. The enclosure meets IP65, protecting internal coils and electronics against dust intrusion and water jets in industrial environments. A weight of 2.5 kg keeps the unit light enough for manifold assemblies without additional support.
