Description
The Bosch Rexroth 4WRE6 valve is a direct-operated proportional directional valve with integrated control electronics (OBE) and electrical position feedback, designed for precise closed-loop control of hydraulic flow direction and volume.🔧 Design & FunctionThe 4WRE6 valve is a 4/3-way (three-position, four-port), spring-centered component for subplate mounting.It uses proportional solenoids to move a control spool, with travel distance proportional to the electrical input signal. The spool progressively opens V-shaped grooves to regulate flow.The closed-loop position control is a key feature. An inductive position transducer (LVDT) continuously monitors the spool's actual position and compares it to the commanded value. The integrated electronics (OBE) process the command and feedback signals, correcting deviations for high accuracy and repeatability.📋 Key Technical SpecificationsSpecification DetailValve Type 4WRE6 - Proportional Directional Valve with OBEFunction 4/3-way (3 positions, 4 ports), spring-centeredOperation Direct operated with integrated electronicsNominal Size 6 (NG6 / CETOP 03)Mounting Standard ISO 4401-03-02-0-05Max.
