DN40-100 Industrial butterfly valve China Manufacturer Details

There are many types of Butterfly Valve materials, including the following：

1、Grey cast iron and ductile iron materials.

These two materials are commonly used in water system pipelines, and there are some differences between the two. The ductile iron material has a higher spheroidization rate and higher hardness. And the malleable iron material is better and has a longer service life.

2、 Cast steel material

Cast steel Butterfly Valves are generally used in high-temperature and high-pressure environments, such as steam and oil media.

3、 Stainless steel material

Stainless steel material has good anti-corrosion and rust prevention properties, so if the medium inside the pipeline has a certain degree of corrosiveness, stainless steel butterfly valves can be used. Also, if the pipeline environment is prone to metal corrosion, stainless steel butterfly valves can be used.

4、 Aluminum alloy material

Aluminum alloy material has characteristics such as low water absorption, thermal insulation and cold insulation, and corrosion resistance. Aluminum butterfly valves are often used in air conditioning cooling water systems to prevent condensation.
