The M-3SEW10U1X/420MG96N9K4/B18V valve is produced by Bosch Rexroth within the M-SEW Poppet Valves series. It serves as a switching element in hydraulic automation where discrete on-off control of flow is required. The valve follows a 3/2-way configuration identified by symbol U, allowing it to direct pressure to a single actuator port while providing an alternate path to tank. A direct-operated seat design gives fast closure against the ports and reduces leakage. Three main ports accommodate pressure, service, and return lines in compact manifolds. The unit withstands operating pressures up to 420 bar when working with mineral oil-based fluid, supporting high-pressure circuits. Actuation is delivered by an air-gap DC solenoid, energized at a nominal 96 V DC, and the coil accepts a ±10 % voltage variation without performance loss. Continuous energization is possible because the duty cycle is specified at 100 %.
Electrical termination is handled through a DIN EN 175301-803 connector coded K4, simplifying field wiring and sealing. The energized solenoid draws 30 W, matching control cabinet power budgets in mobile or stationary equipment. An IP65 enclosure rating protects the coil and pole tube against dust ingress and low-pressure water jets during wash-down. FKM seals resist common hydraulic oils and elevated temperatures, maintaining tight shut-off over service life. A concealed manual override marked N9 enables local shifting of the poppet during commissioning or in the absence of power. Flow can be metered by a 1.8 mm throttle insert identified as B18, which limits the opening and moderates actuator speed.
