Product description
Pneumatic fluorine-lined flange butterfly valve is composed of tetrafluoroethylene sealed butterfly valve, pneumatic actuator and triple parts. Pneumatic fluorine-lined butterfly valve adopts full-lined (F3, F4, F46) polymer materials on the flow path, butterfly plate and valve stem, which has good anti-corrosion performance. It is suitable for pipelines with corrosive or cleanliness requirements, such as alkali, reducing agent, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, organic acid, strong acid, concentrated vinegar and other strong corrosive media. Using compressed air as the drive, receiving industrial signals to adjust and switch the butterfly valve by cooperating with the positioner or solenoid valve. It is used to adjust the flow rate and intercept the medium in the water supply and drainage and gas pipelines of food, medicine, chemical industry, petroleum, electric power, papermaking, etc.
Main feature
1. Novel and reasonable design, unique structure, light weight, and rapid opening and closing.
2. Small operating torque, convenient operation, labor-saving and dexterous.
3. It can be installed in any position, and the maintenance is convenient.
4. The seals can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage.
5. The sealing material is resistant to aging, corrosion, and has a long service life.
