The 4WRZE25W6-220-7X/6EG24N9ETK31/A1D3M proportional directional valve is produced by Bosch Rexroth as part of the WRZ Proportional Directional Valves series. It meters flow and controls actuator direction in hydraulic automation circuits. Size 25 defines the envelope and porting capacity for large manifolds. A 24 V DC supply voltage powers the integrated electronics that shift the spool. The ±10 V command signal acts as the reference from a motion controller for proportional positioning. A nominal flow of 220 l/min at a 10 bar pressure drop supports high-volume transmission lines, while a maximum operating pressure of 350 bar in the pressure and work ports enables use in high-pressure systems. Internal pilot oil supply eliminates external feed lines, and the ISO 4401-08-07-0-94 mounting interface matches standard subplates. The valve weighs 18.4 kg, so the manifold or bracket must support that mass.
During continuous operation the electronics draw up to 1.8 A, and a 3 A power pulse is required to initiate spool movement before settling to the steady value. A 100 percent duty cycle lets the unit remain energized without thermal pauses. Electrical termination is handled through an EN 175201-804 plug, simplifying field wiring. A concealed manual override allows local actuation for setup or emergency use without exposing moving parts. Pilot oil drain is internal, so pilot flow returns through the valve body and does not need an external hose. The IP65 protection class shields the enclosure against dust ingress and low-pressure water jets, making it suitable for mobile or exposed installations. Return pressure in port T can reach 30 bar, allowing the drain line to share back-pressure conditions common in compact hydraulic circuits.
