The 4WRL10V1-85M-3X/G24ETK0/M-750 valve belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and is intended for precise hydraulic control in automated machinery. It installs on an ISO 4401-05-05-0-94 interface, allowing direct mounting on standard sub-plates. Electrical supply is 24 V DC, and the coil draws up to 40 VA while limiting current to 2.7 A for stable actuation. Continuous operation is supported by a 100 percent duty cycle, so the solenoid may remain energized without forced cooling periods. Flow adjustment follows a progressive characteristic identified by code “M,” enabling fine modulation at low command signals. With a rated flow of 85 L/min at a 5-bar control edge, the unit handles typical circuit demands efficiently. Pilot oil returns internally through ports X and Y, simplifying external plumbing. The V1 spool symbol defines the porting pattern that pairs with proportional pilot stages for bidirectional metering.
The valve passes up to 170 L/min when fully shifted, delivering high volume for large actuators. Working ports A and B tolerate operating pressures to 350 bar, while the tank, X, and Y lines are limited to 250 bar to protect return components. Pilot supply can reach 250 bar but must not fall below 10 bar to maintain stable spool positioning. Environmental sealing meets IP65, so the enclosure resists dust ingress and low-pressure water jets when the electrical connector is properly fitted. Unit mass is 8.35 kg, which should be considered when sizing manifold supports and service tools.
