The M-3SEW6U3X/420MG24N9K4QMAG24/P poppet valve belongs to the M-SEW Poppet Valves series from Bosch Rexroth and serves to open or block flow paths in hydraulic automation. It is built in size 6, matching compact subplate manifolds. A porting pattern compliant with ISO 4401-03-02-0-05 (NFPA D03) allows direct mounting on standard D03 subplates. The valve carries a maximum flow rating of 25 l/min for medium-capacity circuits and withstands operating pressures up to 420 bar, while the tank port is limited to 100 bar to protect return plumbing. An integrated check valve insert prevents reverse flow and maintains load holding when the main poppet is closed. NBR seals contain mineral-oil-based fluids, and a protection class of IP65 shields the solenoid enclosure from dust and water during wash-down maintenance.


The solenoid operates on 24 V DC and draws 30 W, providing rapid poppet actuation. Continuous energization is permitted because the duty cycle is 100 %, and a ±10 % voltage tolerance keeps performance stable when the supply varies. Electrical termination is through a DIN EN 175301-803 connector coded K4, simplifying field wiring with molded plugs. A concealed manual override lets maintenance staff shift the valve without energizing the coil for setup or emergency venting. A position switch marked QM in position “a” sends a 24 V DC confirmation signal to machine interlocks, verifying that the poppet is in the energized state. The sealed housing around the switch maintains the same environmental protection as the solenoid enclosure, supporting reliable feedback in harsh plant conditions.
