The 4WRL16V120M-3X/G24Z4/M proportional solenoid valve belongs to the 4WRL Solenoid Valves series and is produced by Bosch Rexroth to meter hydraulic oil in automated machinery. It fits the ISO 4401-07-06-0-94 mounting interface for straightforward subplate installation, and a DIN 43560-AM2 connector simplifies electrical hookup. The coil operates from a 24 V DC supply, with a maximum solenoid current of 2.7 A so the control unit can drive the spool through its full range. Power consumption is limited to 40 VA, reducing thermal load in the enclosure. The spool is identified by symbol V and follows an M progressive flow characteristic, providing gradual port opening for accurate motion control. At a 10 bar pressure drop the valve passes a nominal flow of 120 l/min, while peak demand can be covered up to 450 l/min.
Ports P, A, and B withstand operating pressure up to 350 bar, permitting use in high-pressure circuits, whereas ports T, X, and Y are restricted to 250 bar to protect return and pilot lines. The pilot stage functions between 10 bar and 250 bar so it remains responsive at low standby pressure yet tolerates system surges; its own flow requirement is 12 l/min for rapid spool actuation. NBR seals compatible with HL and HLP fluids maintain tightness under temperature and pressure variations. The assembled valve weighs 10 kg, giving it sufficient mass for rigid mounting without auxiliary supports.
