PRODUCT OVERVIEW

The pneumatic fluorine lined wafer butterfly valve is composed of Teflon sealed butterfly valve, pneumatic actuator and triple parts. The pneumatic fluorine lined butterfly valve is made of fully lined (F3, F4, F46) polymer materials on the flow channel, butterfly plate and valve stem, which has good anti-corrosion performance. It is applicable to 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. Driven by compressed air and receiving industrial signals, the butterfly valve can be adjusted and opened by cooperating with positioner or solenoid valve. It is used for regulating flow and intercepting medium on water supply and drainage and gas pipelines such as food, medicine, chemical industry, petroleum, electric power and papermaking.


MAIN FEATURES 

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 at any position and easy to maintain.

4. The seals can be replaced with reliable sealing performance to achieve two-way sealing and zero leakage.

5. The sealing material has the characteristics of aging resistance, corrosion resistance and long service life.
