The 4WRL16W3-180S-3X/G24Z4/WX02M-924 valve belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and serves as a proportional control element in hydraulic automation circuits. It is supplied in nominal size NG16, matching mid-range manifold blocks for mobile and industrial machinery. The ISO 4401-07-06-0-94 mounting pattern allows direct installation on standardized subplates without adapter plates. A maximum flow of 450 l/min supports high actuator velocities, while ports P, A, and B tolerate up to 350 bar so main pressure lines remain secure under full load. Return and pilot ports T, X, and Y are limited to 250 bar, maintaining safety margins in low-pressure passages. The pilot stage works between a minimum of 10 bar and a maximum of 250 bar, and its own flow of 12 l/min shifts the main spool without delay. Hysteresis is limited to 0.1%, ensuring repeatable positioning during closed-loop operation.
The valve runs on a 24 V DC supply and draws 40 VA, so it can be powered from standard machine control transformers. A peak solenoid current of 2.7 A defines the required rating for the external amplifier. Wiring is completed through a DIN 43560-AM2 plug, simplifying field replacement and service. Command changes propagate to full stroke in 40 ms at 100 bar pilot pressure, providing rapid response for dynamic load control. The IP65 protection class guards the enclosure against dust and water jets when a sealed mating connector is fitted. A weight of 10 kg adds mass that helps damp vibration in block-mounted assemblies. These electrical and physical parameters confirm suitability for precise, fast-acting hydraulic automation.
