The 4WRL16W180S-3X/G24ETZ4/WX02M-748 valve belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and regulates pressure and flow in hydraulic automation loops. The solenoid operates on a 24 V DC supply and can draw up to 2.7 A, with overall power consumption limited to 40 VA. A 100 % duty cycle allows continuous control without thermal pauses, while spool position hysteresis remains below 0.1 % for repeatable metering. The housing is sealed to IP65 according to DIN 40050, protecting internal components against dust and low-pressure water jets. Installation is by the ISO 4401-07-06-0-94 subplate pattern, and the assembled unit weighs 10 kg.
The main stage passes up to 450 L/min so high-flow actuators can be supplied without additional boosters. Working ports p, a, and b withstand 350 bar, whereas tank-related ports t, x, and y are limited to 250 bar to safeguard return circuits. Pilot oil is taken internally and returned internally, eliminating external pilot lines and reducing leak points. The pilot circuit accepts pressures from 10 to 250 bar and delivers 12 L/min to the control spool so shift times stay short even under load.
