Fluorine Lined Check Valve
Product overview
Fluorine lined check valve is suitable for -50℃~150℃ of various concentrations of Aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants, FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipeline use.
Product Features
The valve disc of fluorine lined check valve is disc-shaped and rotates around the rotary axis of the valve seat channel. Because the channel inside the valve is in the shape of a flow line, the flow resistance is small, and it is suitable for the large-caliber pipe occasions with low velocity and inconstant change of flow.
