The 4WRREH6VB25P-1X/G24K0/B5M proportional directional valve is supplied by Bosch Rexroth within the 4WRE Proportional Directional Valves series. It meters hydraulic flow in automation circuits where closed-loop electronic control is required. A connector built to DIN 43563-AM6 defines the mechanical interface for the plug-in electronics, and the 11P+PE plug brings all power and signal conductors together. Internal electronics operate from a 24 V DC supply voltage, while the spool is commanded by a ±10 V setpoint input that matches the ±10 V DC feedback signal returned for position monitoring. Dynamic cycles are handled by a response time of no more than 5 ms from 0 to 100 percent stroke. The P flow characteristic with a 60 percent kink shapes the opening curve, and hysteresis stays at or below 0.2 percent to maintain precise repeatability.
For continuous service the valve carries a cyclic duration factor of 100 percent, eliminating duty-cycle limits. An IP65 degree of protection shields the housing from dust and low-pressure water jets. Installation follows the ISO 4401-03-02-0-94 mounting pattern for compatibility with standard subplates. A nominal flow rate of 25 L/min is achieved at a 70 bar differential, and ports p, A, and B tolerate working pressures up to 315 bar, while the tank port is rated for 100 bar. NBR seal material resists common hydraulic oils and supports long service life. The valve weighs 2.5 kg, which simplifies handling during manifold assembly.
