    Stainless Steel Vertical Check Valve

    Product details

    H42W stainless steel vertical check valve is normally in the closed state, due to the pressure of the inlet medium in the pipeline, and overcome the spring resistance to open the valve.When the medium pressure at the inlet end is lower than the outlet end, the spring will push the spool toward the valve seat and make the valve close, to prevent the medium counterflow, so the start-stop effect.The valve adopts spring to support the valve core, so it can be installed vertically or horizontally.
