The M-3SEW6U3X/420MG24K4 valve belongs to the M-SEW Poppet Valves series and is manufactured by Bosch Rexroth for precise on/off control in hydraulic automation. It performs as a 3/2 directional seat valve, so it routes pressure from the supply to one work port or blocks flow as required. A nominal size of 6 keeps the body compact for space-limited manifolds. Its maximum operating pressure of 420 bar allows use in high-pressure circuits without derating. The unit can pass up to 25 l/min, setting flow capability for medium throughput actuators. A 100% duty cycle permits continuous energization of the solenoid without enforced cooling pauses. The coil is designed for 24 V DC, and a voltage tolerance of ±10% accepts normal supply variation. Electrical demand is 30 W, an important figure when sizing power supplies and calculating heat generation.
The electrical connection is a DIN EN 175301-803 K4 plug, enabling quick replacement and sealed coupling. IP65 protection class guards the enclosure against dust ingress and low-pressure water jets. Coil surface temperature is limited to 120 °C, preventing insulation damage during prolonged operation. The valve can be installed in any position, which simplifies layout inside compact machinery. There is no manual override, so all shifting commands must come from the electrical control system. A position switch is not present, meaning external sensors are necessary if end position feedback is needed. Fluid entering the valve must meet ISO 4406 cleanliness class 20/18/15 to protect the seat against wear. Total weight is 1.5 kg, so a single technician can handle the component during maintenance.
