The 4WRL10W80S-3X/G24ETZ4/M valve belongs to the 4WRL Solenoid Valves series manufactured by Bosch Rexroth for proportional control tasks in hydraulic automation systems. It is energized by a 24 V DC supply, and the coil can draw up to 2.7 A so that the spool reaches its commanded position even at rated load. A 100 % duty cycle permits the solenoid to remain energized without thermal pauses, supporting closed-loop applications that demand constant modulation. The electrical interface uses a DIN 43650/ISO 4400 M16×1.5 (2P+PE) connector, and the housing meets IP65, protecting the internals from dust ingress and water jets on outdoor machinery. Installation is straightforward because the body matches the ISO 4401-05-05-0-94 mounting pattern, while an internal pilot oil supply and return eliminate external pilot lines. Position feedback electronics receive a dedicated +15 V, 35 mA feed to power the transducer. The valve employs NBR seals to maintain leakage control with common mineral-based hydraulic oils between −20 °C and +80 °C.
For flow regulation, the valve handles up to 170 l/min, enabling medium-frame actuators to move quickly without adding parallel circuitry. Working ports p, a, and b tolerate 350 bar, giving designers headroom for high-pressure systems, whereas ports t, x, and y are rated at 250 bar to safeguard return and pilot channels. Pilot actuation begins once system pressure reaches 10 bar and remains linear up to a pilot limit of 250 bar, preserving proportional accuracy throughout the stroke. The internal hydraulic architecture supports these ratings without external cooling or filtration modifications, and the flow path dimensions keep pressure drop low at peak demand. By combining the stated flow capacity with wide pressure margins, the 4WRL10W80S-3X/G24ETZ4/M integrates easily into presses, test stands, and motion axes that rely on rapid yet repeatable oil delivery.
