M-SEW Poppet Valves

The Bosch Rexroth Type M-SEW Poppet Valves are direct operated directional seat valves used in hydraulic systems, available in 2/2, 3/2, or 4/2 designs. Their primary function is to control the start, stop, and direction of fluid flow for applications requiring a reliable and robust switching element. These size 6 valves are rated for a high maximum operating pressure of up to 420 or 630 bar with a maximum flow of 25 l/min. The valves are actuated by air-gap DC solenoids with detachable coils that can be rotated for installation flexibility. Although they operate with a short-duration negative spool overlap during switching, this momentary leakage is considered negligible in nearly all applications.
