M-3SEW6U3X/420MG24N9K4/PV

The M-3SEW6U3X/420MG24N9K4/PV poppet valve belongs to the M-SEW Poppet Valves series from Bosch Rexroth and directs pressure fluid in hydraulic automation circuits. It functions as a 3/2 valve (symbol U), so it alternates flow between two paths while providing one blocked port. The nominal size 6 defines the mounting interface and contributes to the specified flow range. A maximum operating pressure of 420 bar lets the unit serve high-pressure lines without external boosters. The permitted flow of 25 l/min sets the throughput limit for stable switching and avoids excessive pressure drop. A 24 V DC coil voltage energizes the solenoid for actuation, and the 30 W power draw helps users choose an adequate electrical supply and thermal dissipation. Its 100 percent duty cycle allows the coil to remain energized continuously without overstress. A mass of 1.5 kg keeps manifold loading low and simplifies handling during installation.

The solenoid mates with a DIN EN 175301-803 connector, giving a standardized plug layout for quick wiring in control cabinets. When the matching plug is fitted, the enclosure reaches IP65, so dust and low-pressure water jets cannot penetrate the coil housing. An integrated check valve blocks reverse flow and maintains load position when the valve is de-energized. A concealed manual override lets maintenance staff shift the poppet during power loss while preventing accidental activation in normal service. The coil surface may reach 120 °C; this temperature limit guides enclosure ventilation and insulation choice. The body follows the ISO 4401-03-02-0-05 porting pattern, so it mounts on common NG6 subplates without adapter blocks. Port B is supplied as a blind counterbore in the 420 version, which seals that path for the intended circuit function. FKM seals resist many hydraulic oils and elevated temperatures, reducing leakage and extending service intervals.
