| ![Fluorine-lined butterfly valve]() ![Fluorine-lined butterfly valve]() | Overview:
The butterfly valve is a butterfly plate that rotates together with the valve stem as a starting and closing member for realizing the opening, closing and adjustment of the valve. The lining butterfly valve is a thick polymer material with lining technology on the flow parts, valve body, butterfly plate and valve stem. It has excellent corrosion resistance and can be applied to any concentration of acid, alkali, salt and oxidant, reducing agent. The medium such as organic solvent is an ideal product for the use of shut-off and regulating equipment in gas, liquid, semi-fluid pipelines and vessels of chemical, petroleum, pharmaceutical, food, steel smelting, papermaking, hydropower and other systems, and can replace gate valves, Globe valves and other types of shut-off and regulating valves.
Uses: The fully lining polytetrafluoroethylene (F4), polychlorotrifluoroethylene (F3) and polyfluoroethylene propylene (F46) fluoroplastic lining valves produced by our factory have the advantages of corrosion resistance, no leakage and long service life. Suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing medium or high temperature ene sulfuric acid, high temperature concentrated acetic acid, acid and alkali alternate and various organic solvents and other highly corrosive media.
Structural features:
1 small size, light weight, light weight, easy to install and repair.
2The sealing performance is excellent and reliable, zero leakage and long service life.
3 The flow characteristics tend to be straight, and the adjustment performance is excellent.
4The structure is simple, the switch is rapid, and the 90° rotation is opened and closed.
5 can replace the use of various valves such as gate valve, globe valve, plug valve, hose valve and diaphragm valve.
6 Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
7 Replacement parts lining material can be applied to a variety of media.
