Lined Check Valve

XDV Lined check valve only allows the medium to flow in one direction and prevents the fluid from flowing back. Usually, this valve works automatically. Under the pressure of flow in one direction, the valve disc opens. When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc or PTFE valve ball act on the valve seat, so as to cut off the fluid. It is applicable to aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acid sand strong oxidants of various concentrations, as well as strong alkali organic solvents of various concentrations and pipelines of other corrosive gases and liquid media.
