The PTFE Lined Butterfly Valve adopts a fluoroplastic coated disc with a spherical sealing surface, and a silicon rubber gasket at the base of the valve seat to adjust the sealing performance of the valve; The valve is light in operation, tight in sealing performance and long in service life. It can be used for quick cut-off or flow regulation. Suitable for occasions requiring reliable sealing and good adjustment characteristics.
The valve body adopts the split type, and the sealing at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the disc and the seat, so as to achieve compact structure, beautiful appearance, reasonable process and reliable performance. Ensure that the valve shaft does not contact with the fluid medium in the cavity. It is convenient to replace the valve shaft. The valve can be completed without detaching from the pipeline.

The products are widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in the occasions with severely corrosive media such as sulfuric acid, hydrofluoric acid, phosphorus, acid, chlorine gas, strong alkali, aqua regia, etc.
Any concentration of acid, alkali, chlorine, hydrogen sulfide strong oxidant, concentrated nitric acid, etc.
1. Centerline structure, the whole disc and the seat are concentric within a 360° circle (centerline), with bidirectional sealing function;
2. Four-stage loading elastic seal to ensure zero leakage;
3. The radial direction of the valve shaft is sealed by a combination of O-ring and metal gasket;
