4WRREH6VB24L-1X/G24K0/B5M

The 4WRREH6VB24L-1X/G24K0/B5M proportional directional valve is built by Bosch Rexroth within the 4WRE Proportional Directional Valves series. The unit regulates flow and direction in hydraulic automation circuits where accurate servo control is needed. It is supplied in nominal size NG6, which aligns with compact manifold layouts in small to medium power stages. A 4/3-way spool arrangement permits bidirectional actuator movement with a centered neutral position. Installation follows the ISO 4401-03-02-0-94 mounting interface so the valve can bolt directly onto standardized sub-plates. Under rated conditions it delivers a nominal flow of 24 l/min at a pressure drop of 70 bar, while the linear flow characteristic simplifies proportional command scaling. Dynamic response is supported by a 5 ms rise time from 0 to 100 percent, and total hysteresis is limited to 0.2 percent to keep positioning errors minimal. Electrical actuation accepts a ±10 V setpoint so the valve can connect to common analog motion controllers without signal conversion.

Environmental and electrical parameters protect performance in demanding plant areas. The housing carries an IP65 degree of protection, preventing dust ingress and shielding the coils from water jets during maintenance wash-downs. Power is supplied at 24 V DC, and the integrated electronics draw 30 VA, allowing compact power supplies to run multiple valves on one rail. Control wiring is terminated through an 11P+PE plug so field replacement is quick and polarity secure. The hydraulic design tolerates working pressures up to 315 bar on ports P, A, and B, while the tank port withstands 100 bar, permitting high-load actuators without external reliefs. NBR seals contain mineral oil based fluids and maintain leakage tightness across the stated pressure range. System cleanliness must be maintained to ISO 4406 class 18/16/13 or better to prevent spool jamming and wear. Together these characteristics ensure reliable service in closed-loop position or force control tasks that require repeatable proportional metering.
