The M-3SEW6C3X/420MG110N9K4 belongs to the M-SEW Poppet Valves series from Bosch Rexroth and is intended for directional control in hydraulic automation. Its size 6 body fits subplates that follow the ISO 4401-03-02-0-05 (D03) pattern, allowing straightforward installation on standard manifolds. The unit performs a 3/2 switching function identified by symbol C, so it directs flow between three ports and two positions within a circuit. A maximum operating pressure of 420 bar enables use in high-pressure systems, while a maximum flow of 25 l/min supports moderate actuator speeds. The assembly weighs 1.5 kg, which eases manual handling during mounting. NBR seals are fitted to maintain compatibility with common hydraulic fluids and to hold pressure reliably.


A high-power air-gap solenoid provides actuation and draws 30 W at 110 V DC, producing the force needed to shift the poppet without pilot oil. The coil supports a continuous 100 % duty cycle, and its surface may reach 120 °C without exceeding thermal limits. For rapid cycling the valve can switch up to 3600 times per hour when system pressure is above 350 bar. Electrical termination is through a DIN EN 175301-803 plug coded K4, and a concealed manual override labeled N9 allows local operation during setup or power loss. The enclosure is rated IP65 to resist dust and water jets, protecting the coil and connections in harsh plant environments.
