The 4WRL25EZ350S-3X/G24ETZ4/M-750 is produced by Bosch Rexroth within the 4WRL Solenoid Valves series and is intended to modulate hydraulic flow and direction in automated circuits. It operates on a 24 V DC supply and draws up to 2.7 A through a DIN 43650/ISO 4400 connector, while overall power consumption remains limited to 40 VA. Continuous operation is supported by a 100 percent duty cycle, so the control coil can stay energized without cooldown intervals. The actuating time from 0 to 100 percent stroke at 100 bar is 45 ms, allowing rapid response when command signals change. Pilot oil for ports X and Y is routed internally, simplifying external plumbing. The unit follows the ISO 4401-08-07-0-94 mounting pattern for direct installation on standard sub-plates or manifolds.
With a maximum operating pressure of 350 bar at ports P, A, and B, the 4WRL25EZ350S-3X/G24ETZ4/M-750 handles high-pressure lines in presses and similar equipment. Pilot control tolerates pressures between 10 bar and 250 bar, and ancillary ports T, X, and Y are limited to 250 bar to protect seals and casting integrity. The valve passes up to 900 l/min of oil, matching large-flow power units without inducing excessive pressure drop. An IP65 protection class resists dust and low-pressure water jets when the connector is properly fitted, whereas NBR sealing material maintains compatibility with common mineral-based fluids. Installed mass is 18 kg, so rigid mounting surfaces are required to prevent vibration. These characteristics complete a high-capacity proportional stage that can be piloted internally without external drain lines.
