The M-3SED6CK1X/350CG24N9K4 valve belongs to the M-SED Poppet Valves series and is produced by Bosch Rexroth for hydraulic automation where compact, high-pressure flow control is required. It performs a 3/2 directional poppet function, allowing one inlet to be switched between two outlet paths, and three main ports support this routing. A wet-pin solenoid with a detachable coil actuates the poppet so that coil replacement can be completed without opening the hydraulic chamber. The coil runs on direct current, accepts a nominal 24 V supply, and tolerates voltage variations of ±10 % to handle minor line deviations. Steady energization draws 30 W, balancing response time with energy use. The valve body withstands operating pressures up to 350 bar, enabling installation in high-pressure circuits found in industrial power units.
A 100 % duty cycle allows the unit to stay energized continuously, and coil insulation supports temperatures to 150 °C so performance is maintained during sustained service. To suit rapid sequencing, the poppet can complete 15,000 switching actions per hour. Electrical termination is made through a DIN EN 175301-803 K4 connector, providing a standardized interface for field wiring. A concealed manual override, coded N9, lets technicians shift the spool locally during setup without exposing internal parts. The housing achieves an IP65 protection level, so dust and low-pressure water jets do not impair operation when the connector is correctly installed. NBR seals are fitted to withstand common hydraulic oils and reduce leakage over long cycles. For reliable movement, the hydraulic fluid should meet a cleanliness level of ISO 4406 class 20/18/15, which limits particulate wear on the poppet and seat.
