Material of the lined fluorine butterfly valve

Laminated Pancake Fluorine-lined Butterfly Valve The structure is relatively simple, generally consisting of four parts: valve body, valve seat, transmission mechanism, and valve plate. Due to its use in various environments and working conditions, the materials used in manufacturing may also vary.
There are generally three types of materials used for valve bodies, namely cast iron, cast steel, and stainless steel. In terms of performance, stainless steel is generally higher than cast steel than cast iron. Made of cast iron material Clamp type fluorine lined butterfly valve It is generally used in pipelines with normal temperature and pressure and non corrosive media, with relatively low cost. Stainless steel with better performance is generally used in pipelines with corrosive media, and the cost is also higher among the three materials.

The material of the valve plate and the valve body of the fluorine lined butterfly valve are roughly similar, but due to the fact that the valve plate is located inside the pipeline and is subject to significant erosion and corrosion by the medium, the general performance requirements are higher than those of the valve body material. For example, if the valve body is cast iron, the valve plate must be cast steel; If the valve body is cast steel, the valve plate must be stainless steel.
The valve seat and stem are usually made of stainless steel.
