4WRP Solenoid Valves

The Bosch Rexroth 4WRP series are high-performance 4/3 servo solenoid spool type valves with positive overlap, designed for subplate mounting in sizes 6 and 10. These are directly operated valves equipped with proportional solenoids and an integrated position transducer for feedback. They work by having the position transducer transmit the spool's actual position back to an external electronic amplifier, which then controls the solenoids to precisely adjust the flow. Functionally, they are essential components for sophisticated electrohydraulic controls in production plants. Ultimately, the valves provide accurate and infinitely variable control over the direction and size of the fluid flow.
