Fluorine Lined Swing Check Valve
Product Introduction:
H44F46 fluorine-lined check valve is a kind of automatic valve that relies on the flow of the medium itself and automatically opens and closes the valve disc to prevent the reverse flow of the medium. The check valve belongs to the automatic valve class, mainly used for the one-way flow of the medium on the pipeline, only allowing the medium to flow in one direction, in order to prevent accidents. H44F46 fluorine-lined check valve is suitable for all kinds of concentrations of aqua royalty, sulfuric acid, hydrochloric acid, and various organic acids, strong acids, strong oxidants at -50℃ ~ 150℃. FEP is also suitable for all kinds of strong alkali organic solvents and other corrosive gases, liquid media pipeline use.

Product Features:
1, suitable for general working conditions and wear or strong corrosive medium special working conditions.
2, swing type fluorine lined check valve without any additional energy device, reduce operating costs.
3, anti reflux reflux effect is good, the use of rubber itself elasticity and reverse back pressure.
4, working through the internal and external pressure difference to realize the natural opening and closing, suitable for strong corrosive media and power station desulfurization.
