The M-3SEW6U3X/420MG24N9K4QMAG24 poppet valve is manufactured by Bosch Rexroth within the M-SEW Poppet Valves series for directing hydraulic flow in automated machinery. It performs a 3/2 switching function identified by symbol U, and its size 6 envelope fits CETOP 03 subplates. An ISO 4401-03-02-0-05 porting pattern aligns its pressure and return passages with standard manifolds. The assembly withstands operating pressures up to 420 bar while passing as much as 25 l/min, so it can control actuators in high-pressure circuits. A 24 V DC solenoid coil drives the poppet; continuous energization is supported by a 100 percent duty cycle, and electrical load is fixed at 30 W. The coil casing may reach 120 °C under sustained service, meaning adjacent components must tolerate that heat.
Ingress protection is rated at IP65, sealing the housing against dust and water jets encountered in factory environments. A DIN EN 175301-803 plug coded K4 provides the electrical interface, and a concealed manual override marked N9 lets technicians shift the valve without power during setup or maintenance. NBR sealing elements contain mineral hydraulic oil and limit external leakage. Spool position monitoring labeled QMAG24 on spool “a” supplies a confirmation signal for control diagnostics. When line pressure exceeds 350 bar, the valve can complete up to 3600 switching cycles per hour without overheating. The unit weighs 1.5 kg, allowing easy installation on compact hydraulic manifolds.
