The 4WRL25E4-350S-3X/G24ETZ4/M solenoid valve belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and regulates hydraulic actuators in automated systems. It fits the ISO 4401-08-07-0-94 mounting pattern for direct subplate installation. Electrical actuation runs on a 24 V DC supply, draws a maximum solenoid current of 2.7 A, and consumes up to 40 VA, values that determine power-supply sizing. A DIN 43650-A connector with an M16×1.5 thread secures the coil wiring. The enclosure is rated IP65 and endures vibration levels to 25 g for reliable service in harsh environments. NBR seals accommodate standard hydraulic oils, and the valve weighs 18 kg, influencing support structure design. System fluid must meet ISO 4406 cleanliness class 18/16/13 to maintain spool integrity.
The valve passes up to 900 l/min, enabling rapid actuation in high-flow circuits. Work ports A and B tolerate 350 bar, while the tank and control ports t, X, and Y are limited to 250 bar, establishing safe operating margins. Internal pilot oil supply and return, identified by the ET code, remove external pilot lines and simplify plumbing. The pilot stage functions between 10 bar and 250 bar, allowing use in both low- and high-pressure control systems. These flow and pressure limits ensure stable proportional control across presses, injection machines, and test rigs.
