The M-3SEW6U3X/420MG24N9K4/P poppet valve is produced by Bosch Rexroth within the M-SEW Poppet Valves series for hydraulic automation tasks that need leak-tight shut-off. It is supplied in size 6, and the 3/2 directional seat design switches pressure, tank, and actuator ports with minimal leakage. A check valve insert is present so return flow can bypass the seat when required. The assembly withstands operating pressures up to 420 bar and carries up to 25 l/min, fitting medium-flow circuits in mobile and industrial equipment. A porting pattern that follows ISO 4401-03-02-0-05 lets it bolt directly to standard subplates. Coil energization uses 24 V DC, and a ±10 % voltage tolerance keeps the solenoid functional during line variation. The duty cycle is 100 %, allowing continuous energization without thermal derating.

The electrical lead enters through a DIN EN 175301-803 K4 connector, providing quick disconnection and reliable sealing. A concealed N9 manual override lets maintenance staff shift the poppet during setup while protecting it from accidental operation in the field. When system pressure exceeds 350 bar, the valve can switch up to 3600 cycles per hour, supporting fast machine sequences. Power consumption is 30 W, so the control supply must budget for that load and its heat. An IP65 housing shields internal parts from dust and water jets for outdoor or wash-down installations. NBR seal material is used, pairing the valve with mineral oil fluids over a common temperature range. The unit weighs 1.5 kg, enabling easy manifold installation without extra support hardware.
