The M-3SEW6C3X/420MG24N9K4/B15 belongs to the M-SEW Poppet Valves series produced by Bosch Rexroth and provides on-off control for hydraulic automation as a 3/2 directional seat valve. A high-power solenoid supplies the force required to shift the poppet, allowing dependable switching at operating pressures as high as 420 bar. The valve accommodates flows up to 25 l/min so standard size 06 lines maintain acceptable pressure loss. Continuous energization is supported by a 100 percent duty cycle, which keeps actuators held without overheating. A 24 V DC nominal supply matches common machine control voltages, and the coil draws 30 W to balance response speed with thermal output. Interchangeable installation is achieved through the ISO 4401-03-02-0-05 mounting pattern, while a weight of 1.5 kg permits manual handling during manifold service.
Electrical connection is made with a DIN EN 175301-803 K4 plug, giving quick wiring and secure strain relief; when the mating connector is fitted the assembly attains an IP65 protection rating against dust and water jets. A concealed manual override marked N9 lets maintenance personnel shift the valve without power yet prevents accidental actuation in daily use. The coil insulation system tolerates surface temperatures up to 120 °C so the device remains functional in hot manifolds. Hydraulic cleanliness must reach ISO 4406 (c) 20/18/15 to limit seat wear and maintain leak-free closure. The return gallery can be pressurized to 100 bar, expanding placement options in boosted tank systems. A 1.5 mm throttle orifice identified as B15 meters pilot flow to soften switching impacts and reduce system shock.
