M-3SEW10C1X/420MG125N9K4

The M-3SEW10C1X/420MG125N9K4 poppet valve is produced by Bosch Rexroth within the M-SEW Poppet Valves series and is intended to switch hydraulic flow in automated machinery. Its nominal size 10 provides mounting dimensions suited to medium capacity manifolds, while the 3/2-way directional function allows the valve to alternately connect or block a working port for pressure or tank lines. Actuation is by direct solenoid so movement of the poppet occurs without pilot oil, giving fast response in closed-loop controls. The air-gap DC coil is detachable, allowing coil replacement without opening the hydraulic circuit, and it runs from a 125 V DC supply to match common industrial bus voltages. Power consumption is limited to 30 W which simplifies power budgeting in compact control boxes, and the design is rated for a 100 percent duty cycle so the coil may remain energized continuously without thermal derating. Switching logic follows spool symbol C, letting designers match circuit diagrams to the valve configuration.

The unit withstands operating pressures up to 420 bar, enabling use on high-pressure systems such as clamping or injection circuits, and it permits a maximum flow of 40 l/min so line sizing can be verified for acceptable pressure drop. Port connections follow the ISO 4401-05-04-0-05 pattern which standardizes mounting on subplate manifolds to reduce plumbing time. Electrical termination is via a K4 connector according to EN 175301-803, giving a sealed plug interface compatible with field wiring harnesses. An IP65 protection class shields the solenoid housing from dust and water jets in typical plant environments, while meeting cleanliness class ISO 4406 20/18/15 ensures that acceptable oil filtration levels are defined for reliable seat sealing. A concealed manual override designated N9 lets technicians shift the valve during commissioning without energizing the coil, and the overall weight of 2.0 kg aids handling when installing or replacing the component.
