The M-3SEW6C3X/630MG125N9K4/PV valve belongs to the M-SEW Poppet Valves series and is manufactured by Bosch Rexroth. It is intended for hydraulic automation circuits where dependable on/off control is needed. The unit operates as a 3/2 directional seat valve, providing leak-tight closure in both flow directions. With nominal size 6, it occupies minimal manifold space while still handling service loads. Actuation is supplied by a high-power air-gap solenoid whose coil is rated at 125 V DC and consumes 30 W when energized. Continuous duty is supported by a 100 % duty cycle, preventing thermal shutdowns during prolonged shifts. The body tolerates operating pressures up to 630 bar and accommodates flow rates to 25 l/min without exceeding its design limits.


For electrical hookup, the coil mates with a rectangular connector conforming to DIN EN 175301-803, simplifying field wiring. Mineral oil is defined as the working fluid, matching the material compatibility of the internal parts. A concealed manual override allows technicians to shift the poppet manually during commissioning or in power loss scenarios. The return line may see tank port pressures up to 100 bar while maintaining seat integrity. Mounting follows the ISO 4401-03-02-0-05 porting pattern, so the valve fits standard subplates and sandwich stacks. An IP65 protection class shields the enclosure from dust and water jets once the connector is fastened. FKM seals resist hot oil and additives, extending service life. The complete assembly weighs 1.5 kg, allowing single-handed installation when space is restricted.
