The 4WRLE10W4-80SJ-3X/G24ETK0/A1M valve is manufactured by Bosch Rexroth for the 4WRL Solenoid Valves series. Designed for closed-loop hydraulic automation, it fits the ISO 4401-05-05-0-05 subplate interface so panel mounting is straightforward. The nominal size NG 10 defines the flow section and allows the unit to pass up to 300 l/min when fully commanded. Service ports p, a, and b can be pressurized to 280 bar, while the t and y ports tolerate 250 bar, giving clear limits for circuit design. Reliable spool movement is maintained as long as a pilot pressure of at least 10 bar is present. With a maximum weight of 9 kg the assembly can be handled without lifting equipment. Continuous operation is possible because the duty cycle is rated at 100 percent, allowing the actuator to remain energized without thermal rest periods.
Electrical control is provided through a 24 VDC supply, and the solenoid consumes up to 40 VA during peak demand. The electronics accept a command signal between −10 V and +10 V so proportional flow can be trimmed from a standard analog controller. Residual ripple on that control line must stay below 2.5 Vpp to avoid spool dithering. The unit carries an IP65 protection class, blocking dust ingress and water jets when the connector seal is fitted. Ambient temperatures may reach 60 °C without derating, and internal components tolerate hydraulic oil prepared to a cleanliness class of 18/16/13 under ISO 4406. NBR seals are used throughout to maintain compatibility with conventional mineral fluids and resist aging. These characteristics combine to deliver predictable performance in mobile or industrial power units where space, pressure capacity, and continuous duty are critical.
