The M-4SEW 6 Y3X/420MG125N9K4/B18V poppet valve belongs to the M-SEW Poppet Valves series from Bosch Rexroth and is intended to open or block hydraulic lines in automated systems. It is built in size 6 and mates with an ISO 4401-03-02-0-05 mounting interface, allowing direct installation on standard subplates. The solenoid operates on 125 V DC, and its coil draws 30 W, providing actuation force while limiting heat. A 100 percent duty cycle permits the coil to remain energized continuously. Wiring is handled through an EN 175301-803 3-pole (2+PE) connector, and when that plug is in place the enclosure attains IP65 protection against dust and water jets. A concealed manual override lets technicians shift the poppet without electrical power when troubleshooting or venting the circuit.
The valve tolerates up to 420 bar on the pressure ports, while the T port must not exceed 100 bar. A 1.8 mm throttle orifice is fitted to moderate flow and cushion switching shocks. Even above 350 bar it can perform 3600 switching cycles per hour, matching rapid-fire operational demands. Flow capacity reaches 25 l/min, making the unit suitable for medium-rate actuators. FKM seals resist aggressive fluids and elevated temperatures encountered in modern hydraulic oils. In circuit diagrams the component is marked with valve symbol Y, indicating its internal flow path. The complete assembly weighs 2.3 kg, so manifold support structures should accommodate this mass.
