The 4WRPH6XB24L-2X/G24Z4/M-842 proportional valve belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth for precise hydraulic automation. It is built to nominal size 6, setting the port dimensions that determine flow paths through the subplate. The mounting pattern matches ISO 4401-03-02-0-94 so it fits standard CETOP 03 manifolds without adapter plates. A nominal flow of 24 l/min at a 70 bar differential allows controlled actuator speeds in medium-duty circuits. Maximum working pressure at ports P, A, and B is 315 bar, enabling operation on high-pressure systems, while the tank port tolerates up to 250 bar to handle back-pressure conditions. The coil is energized from a 24 V DC supply, and the armature can draw up to 2.7 A to reach full spool displacement. Total mass is 2.3 kg, which keeps handling simple during installation or replacement.
A closed-loop position signal of ±10 V is provided for external controllers that require real-time spool feedback. The internal transducer receives ±15 V at 35 mA, ensuring stable excitation for accurate sensing. Electrical interfaces are separated; the solenoid uses a DIN 43650/ISO 4400 two-pin plus earth connector, and the transducer connects through a four-pin Pg7 plug, simplifying field wiring. NBR seals contain hydraulic oil and resist common mineral fluid additives. An IP65 rating protects the housing against dust ingress and water jets, making the valve suitable for exposed machinery zones. System oil must be maintained to ISO 4406 class 18/16/13 cleanliness so that metering edges remain free from abrasive wear. Resistance to vibration up to 25 g prevents performance drift when the valve is mounted on equipment subject to shock or oscillation.
