The M-3SEW6U3X/420MG205N9K4 poppet valve belongs to the M-SEW Poppet Valves series and is manufactured by Bosch Rexroth for directional control in hydraulic automation. With a nominal size of 6, it directs flow in compact manifolds while withstanding a maximum operating pressure of 420 bar. The unit passes up to 25 l/min, matching medium-flow actuator circuits, and tolerates back pressure in the tank line up to 100 bar. Continuous energization is possible because the solenoid is rated for a 100 % duty cycle, draws 30 W, and is powered at 205 V DC. During sustained cycling the coil surface can reach 120 °C, so ambient cooling must be considered.
The valve supports 3600 actuations per hour at pressures above 350 bar to suit high-speed machines. Electrical hookup uses a DIN EN 175301-803 K4 connector, and a concealed manual override lets technicians move the poppet during setup without exposing moving parts. Installation aligns with the DIN 24340 Form A mounting pattern, the ISO 4401-03-02-0-05 porting layout, and the NFPA T3.5.1 R2-2002 D03 interface, allowing direct fit on standard subplates. An IP65 protection class prevents dust and water ingress when the gasketed connector is fitted, and the assembly weighs 1.5 kg to ease handling during manifold installation.
