The M-4SEW10D1X/420MG24N9K4 valve belongs to the M-SEW Poppet Valves series and is manufactured by Bosch Rexroth. It is a direct operated seat valve configured as a 4/2 directional seat valve, allowing two discrete flow paths for hydraulic automation tasks. A high-power air-gap solenoid provides actuation force, and its coil is rated at 24 V DC so it can be energized from standard machine power supplies. Electrical connection is made through a DIN EN 175301-803 plug, enabling rapid removal and service. The design uses mineral oil as the hydraulic fluid and withstands operating pressures up to 420 bar for high-pressure circuit requirements.


Four hydraulic ports support supply, return, and two work lines, fitting the valve into compact manifold arrangements. NBR sealing controls leakage while remaining compatible with the specified mineral oil. A concealed manual override lets technicians shift the poppet mechanically when electrical power is unavailable. The valve is supplied without a check valve insert, throttle insert, or position switch, which simplifies internal flow, minimizes pressure drop, and reduces component count for installations where these auxiliary functions are not required.
