Product Details

Split type Flange Butterfly Valve


The butterfly valve adopts a PTFE-lined butterfly plate with a spherical sealing surface. The valve is easy to operate, tightly sealed, and has a long service life; it can be used to quickly cut off or adjust the flow. It is suitable for occasions requiring reliable sealing and good adjustment characteristics. The valve body adopts a 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 butterfly plate and the valve seat; to ensure that the valve shaft does not contact the fluid medium in the cavity. It is widely used in the transportation of liquid and gas (including steam) in various types of industrial pipelines, and the use of severe corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia, etc. Sexual medium. Its main features are:

1. Novel and reasonable design, unique structure, lightweight, and rapid opening and closing.

2. Small operating torque, convenient operation, labour-saving and smart.

3. It can be installed in any position and maintenance is convenient.

4. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage.

5. The sealing material is resistant to ageing, corrosion, and has a long service life.
