The 4WRLE10W80SJ-3X/G24EK0/A1WX02M-744 valve is manufactured by Bosch Rexroth for the 4WRL Solenoid Valves series. Intended for hydraulic automation, it meters flow and controls pressure to actuators under closed-loop command. The nominal size NG 10 sets the internal flow cross-section for medium-frame machines, while the ISO 4401-05-05-0-05 mounting interface lets the unit bolt directly to standard manifold blocks. A maximum flow capacity of 300 l/min allows rapid cylinder or motor motion, and the external ports p, a, and b can withstand up to 350 bar so high working pressures are possible. Reliable spool actuation begins once 10 bar pilot pressure is available, with 2.4 l/min of pilot oil passing through the W symbol gallery. Continuous operation is supported by a 100 percent duty cycle, preventing coil over-temperature during long production shifts. The IP65 protection class seals the housing against dust ingress and low-pressure water, allowing installation on exposed machine frames.
Dynamic performance is delivered by a 40 ms actuating time from 0 to 100 percent stroke, enabling the controller to adjust flow quickly during process changes. The electronics accept a ±10 V command signal, translating analog setpoints into proportional spool movement, while a 24 V DC supply voltage powers the onboard solenoid assembly. Electrical demand remains moderate at 40 VA, simplifying power distribution in multi-valve banks. Internal clearances are engineered for low leakage; the main stage bleeds only 0.12 l/min and the combined valve plus pilot circuit releases 0.20 l/min, so standby losses stay minimal. The pilot supply line at port X is rated for 280 bar, and the tank return ports T and y handle up to 250 bar, preserving safety margins across all connections. Together these limits, combined with the features listed earlier, support precise, energy-efficient control in high-pressure hydraulic systems.
