The M-3SEW10U1X/420MG96N9K4/P poppet valve belongs to the M-SEW Poppet Valves series from Bosch Rexroth and is installed to switch flow paths in hydraulic automation. It offers three main ports so pressure, return, and actuator lines can be connected directly to the body. A 3/2 directional function identified by symbol U changes the circuit between supply and exhaust positions on command. Port B is supplied as a blind counterbore in this 420 bar version to seal that interface in high-pressure service. A check-valve insert is fitted in port P, and flow from P to A is free while reverse flow from A to P remains closed, protecting the supply line from backpressure. The assembly withstands operating pressures up to 420 bar, and a high-power air-gap solenoid supplies the force needed for rapid poppet movement while drawing 30 W during operation.
A 96 V DC coil energizes the solenoid and remains stable with a ±10 percent voltage tolerance to accommodate line variation. Continuous energization is permitted because the duty cycle is rated at 100 percent, and coil surface temperature may reach 120 °C without damage. A DIN EN 175301-803 K4 connector provides a standardized electrical interface for quick replacement. The housing carries an IP65 protection class so dust ingress and water jets do not impair service life. A concealed manual override lets technicians shift the valve locally while guarding against inadvertent actuation in the field. When system pressure exceeds 350 bar, the valve can switch up to 3,600 cycles per hour, supporting high-duty servo loops.
