M-3SEW10C1X/420MG110N9K4

The M-3SEW10C1X/420MG110N9K4 valve belongs to the M-SEW Poppet Valves series manufactured by Bosch Rexroth for hydraulic automation tasks requiring compact directional control. It operates as a 3/2 unit, switching one pressure port between a work port and a tank line to control actuator movement. A high-power air-gap solenoid drives the poppet for rapid response, and the coil is wound for 110 V DC service so it connects directly to common control supplies. Voltage tolerance of ±10 % lets the coil remain stable when the bus fluctuates, while the duty cycle is rated at 100 %, meaning the solenoid may stay energized continuously without thermal cycling. The assembly withstands operating pressures up to 420 bar (6100 psi), allowing it to manage high-force cylinders and motors. Mineral oil in accordance with DIN 51524 is the designated hydraulic medium, ensuring seal compatibility and predictable viscosity throughout the pressure range.

Power draw of the energized coil is 30 W, and the surface of the winding may reach 120 °C, a limit to consider when defining ambient conditions and wiring insulation. External ingress protection is IP65, so dust and low-pressure water jets do not impair operation when the connector gasket is in place on the DIN EN 175301-803 plug coded K4. The body provides three main ports that match the 3/2 function, and internal flow is mapped by spool symbol C for straightforward circuit diagrams. A concealed manual override identified by code N9 lets maintenance personnel shift the valve without power while safeguarding against accidental actuation during normal service. The direct current coil type complements the DC voltage classification of the product, completing a package suited for mobile or stationary systems where stable low-voltage control is available.
