A 3-port, direct operated poppet solenoid valve, series VKF300 is compact (body width 18mm), yet still provides a large flow capacity. The VKF300 manual overrides are located in 2 directions, on the top and on the side of the valve, providing easy manual operation unaffected by mounting space and piping direction. FKM (Fluoro rubber) is used for the fluid-contact rubber materials, allowing use even in ozone environments.
