The M-3SEW6U3X/420MG110N9K4/V poppet valve belongs to the M-SEW Poppet Valves series from Bosch Rexroth and provides on-off control in hydraulic automation circuits. It is built as a size 6 unit, a dimension that matches common subplate cavities and permits a maximum flow rate of 25 l/min without excessive pressure drop. The valve carries the U (3/2) symbol, indicating three ports and two switching positions so it can alternately connect or block flow paths in compact manifolds. For high-pressure tasks, the body tolerates system pressures up to 420 bar, while the tank port is limited to 100 bar to protect return-line components. Mineral oil is the designated hydraulic medium, and the internal passages are sealed with FKM elastomer rings that also accommodate fluid temperatures up to 80 °C. These characteristics enable the component to cycle reliably in power units that work under elevated pressure and heat.
Electrical actuation is handled by a high-power air-gap solenoid that draws 30 W from a 110 V DC supply, delivering fast poppet movement for repeatable switching. Continuous operation is possible because the coil is rated for a 100 % duty cycle, preventing thermal overload during prolonged machine cycles. A DIN EN 175301-803 type K4 connector establishes the electrical interface, and a concealed manual override (code N9) lets maintenance staff shift the valve when power is absent. The enclosure achieves an IP65 protection class, so dust and low-pressure water jets do not compromise the energized components, provided the mating connector gasket is installed. Safe use in machinery enclosures is further supported by an ambient temperature limit of 50 °C, which aligns with typical cabinet conditions. Together these electrical and environmental features ensure consistent performance when the valve integrates into automated hydraulic manifolds.
