The M-4SEW6D3X/420MG24K4/P valve is manufactured by Bosch Rexroth within the M-SEW Poppet Valves series. It is used in hydraulic automation to shift flow paths with a 4/2 directional seat design, ensuring leak-tight switching for compact circuits. The valve is built in nominal size 6 and mounts on an ISO 4401-03-02-0-05 D03 interface so it can replace standard subplate models without re-machining. It tolerates operating pressures up to 420 bar and allows a maximum flow of 25 l/min, matching medium-pressure actuators in machine tools or presses. A 24 V DC coil draws 30 W during energization, and continuous service is supported by a 100 percent duty cycle. Electrical termination is handled through a DIN EN 175301-803 K4 plug, simplifying field wiring.
Ingress protection is rated at IP65, allowing installation in wash-down zones when the connector gasket is fitted. This enclosure rating also shields the coil from dust ingress during mobile equipment service. The coil insulation permits a surface temperature of 120 °C before derating, maintaining function in hot manifolds. There is a check valve insert that prevents reverse flow when the spool shifts. The poppet is sealed with NBR elastomer to handle common hydraulic oils, provided the fluid cleanliness meets ISO 4406 class 20/18/15. The assembly weighs 2.3 kg, supporting single-person handling during maintenance, and it is supplied without a manual override to reduce envelope size and avoid unauthorized actuation.
