The 4WRL10V55M-3X/G24K0/M-750 solenoid valve belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and meters hydraulic flow to actuators in automated machinery. It is supplied in nominal size 10 so it fits NG10 manifolds, and its ISO 4401-05-05-0-94 mounting interface lines up with standard subplates. A nominal flow of 55 l/min provides stable regulation, while a maximum flow capability of 170 l/min supports rapid motion cycles. The valve tolerates 350 bar on ports p, a, and b, making it suitable for high-force cylinders. An IP65 protection class guards the enclosure against dust and low-pressure water spray. Operation is powered by a 24 V DC supply, and power consumption is 40 VA, factors that guide control cabinet design. The assembly weighs 8.35 kg, information useful for bracket sizing and vibration analysis.
The actuating time from 0 to 100 percent stroke at 100 bar is 25 ms, allowing quick spool shifts in servo loops. Coil resistance is 2.5 Ω at 20 °C, which helps determine driver output requirements, and the solenoid can draw up to 2.7 A under full load. Pilot channels accept up to 250 bar and remain functional down to 10 bar, letting the valve operate with varying pilot supplies; the pilot valve passes 4 l/min to position the main spool. Ports t, x, and y are also rated for 250 bar, enabling remote tank returns that may carry moderate back-pressure. These hydraulic and electrical limits define safe operating envelopes for the valve within high-pressure, fast-acting hydraulic automation systems.
