The 4WRL10W1-80S-3X/G24ETZ4/M solenoid valve belongs to the 4WRL Solenoid Valves series and is manufactured by Bosch Rexroth for precise hydraulic control. It runs on a 24 V DC supply voltage, while the solenoid can draw up to 2.7 A, so the control amplifier must be sized for that load. A coil resistance of 2.5 Ω at 20 °C defines the current-temperature relationship of the winding. Connection is made through a Z4 plug connector specified by DIN 43560-AM2, enabling quick service replacement. The unit can remain energized continuously because it is rated for a 100 % duty cycle. It follows the ISO 4401-05-05-0-94 mounting pattern, allowing direct installation on NG10 subplates that match its nominal size 10 passage geometry. With a maximum flow capability of 170 l/min, the valve supports high-volume circuits without excessive pressure loss.
Ports P, A, and B withstand working pressures up to 350 bar, permitting use in high-pressure actuator loops, while pilot ports X, Y, and drain t are limited to 250 bar to protect the control stage. Hysteresis is restricted to 0.1 %, helping the spool return to the commanded position with minimal deviation. Main stage leakage at 100 bar is 400 cm³/min, a value used to size return lines and reservoir capacity. The pilot oil supply is internal through port X, and the return is also internal via port Y, so no external pilot hoses are required. An IP65 housing according to DIN 40050 shields the electronics from dust and water jets for reliable field operation. NBR sealing material is used, making the valve compatible with standard mineral-oil fluids.
