The 4WRL16W180S-3X/G24EZ4/M valve belongs to the 4WRL Solenoid Valves series produced by Bosch Rexroth for proportional control in hydraulic automation systems. Its nominal size of NG16 accommodates medium-capacity manifolds while keeping pressure losses low. The body follows the ISO 4401-07-06-0-94 mounting pattern, allowing direct installation on standard sub-plates. A maximum flow of 450 l/min permits large-volume circuits to be metered precisely, and hysteresis is held to 0.1 % or less so spool position remains repeatable. The pilot stage becomes functional once pressure at port X rises above 10 bar and stays reliable up to 250 bar; after pilot activation, ports A and B can operate at 350 bar while the tank and drain paths tolerate 250 bar. These limits set the safe operating window for presses, die-casting machines, and other high-demand hydraulic equipment.
The solenoid is powered from a 24 V DC supply, and its coil resistance of 2.5 Ω at 20 °C lets control electronics predict inrush current. During continuous duty the winding can draw as much as 2.7 A, producing a peak power consumption of 40 VA that sustains magnetic force across the stroke. Electrical connection is made through a DIN 43650/ISO 4400 plug with an M16 × 1.5 thread, while an IP65 enclosure rating shields internal components from dust and water jets. NBR seals further isolate the hydraulic passages from external contaminants common in industrial plants. The assembly weighs 10 kg, giving it enough mass to resist vibration yet light enough for single-person handling during maintenance.
