Lift-type fluorine-lined check valve
I. Introduction:
Lined check valves only allow the medium to flow in one direction and prevent flow in the opposite direction. Usually, this type of lined check valve works automatically. Under the action of pressure from flow in one direction, the disc opens; when the liquid flows in the opposite direction, the liquid pressure and the self-weight of the disc act together with the disc on the valve seat, thereby cutting off the flow. Lined check valves include lift check valves, swing check valves, wafer check valves, etc. The H41F46 lined check valve is suitable for use in pipelines of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, various organic acids, strong acids, strong oxidants at concentrations ranging from -50℃ to 150℃. FEP is also suitable for pipelines of strong bases, organic solvents, and other corrosive gases and liquid media at various concentrations.
