Chemical products generally contain corrosiveness (strong corrosiveness, weak corrosiveness), and organic fluorine materials must be used. Organic fluorine materials refer to hydrocarbons containing fluorine elements, which are a very important new chemical material widely used in various fields such as national defense, electronics, machinery, chemical industry, textiles, etc.From the perspective of performance and use, organic fluorine materials mainly include chlorofluorocarbons and their substitutes, fluorinated polymers and their processed products, and fluorinated fine chemicals. However, in order to control the flow of products (materials), some valves (usually fluorine lined ball valves and fluorine lined butterfly valves) must be installed on the pipeline that serve as cut-off and cut-off valves.

What are the specific uses of fluorine lined butterfly valves?

Fluorine lined butterfly valves can be used in various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and various organic acids, strong acids, and strong oxidizing agents. FEP is also suitable for use in pipelines with various concentrations of strong alkaline organic solvents and other corrosive gas and liquid media.

Why is the fluorine lined butterfly valve damaged? What are the reasons for the damage?

There are generally several reasons for damage to fluorine lined butterfly valves: 1. The erosion of the medium causes damage to the fluorine rubber sleeve, which makes the valve disc and valve chamber unable to be completely sealed; 2. Furthermore, the force was not properly controlled during use, causing the manual device (manual fluorine lined butterfly valve) to break.
