The M-3SEW10U1X/420MG96N9K4/B12V poppet valve is manufactured by Bosch Rexroth for the M-SEW Poppet Valves series and is intended to direct hydraulic flow in automated circuits. It provides a 3/2 directional function defined by symbol U, allowing one inlet to be alternately connected to either of two outlets. Actuation is generated by an air-gap DC solenoid that operates on a coil rated at 96 V DC. The coil accepts a ±10 % voltage swing so the valve remains responsive under modest supply variations. Continuous service is possible because the solenoid is specified for a 100 % duty cycle. Electrical connection is accomplished through a DIN EN 175301-803 form K4 interface, while the mating connector is not included with the valve. During energization the coil draws 30 W, a figure useful for sizing power supplies.
The hydraulic section is configured for three main ports that accept mineral oil as the operating fluid. Internal passages include a throttle orifice of 1.2 mm that moderates flow during shifting. Sealing elements are formed from FKM to withstand high-temperature petroleum media. A concealed manual override allows local actuation when power is absent yet remains protected against accidental operation. The valve body endures system pressures up to 420 bar, making it suitable for high-pressure power units. External ingress is limited by an IP65 enclosure rating so spray or dust cannot reach the coil terminals. No spool position monitoring is provided, therefore feedback must be derived from circuit behavior.
