What is the material of turbine butterfly valve

First, gray cast iron and ductile cast iron material

These two materials are more used on the water pipe, but there are some differences between the two, the spheroidization rate of ductile iron material is higher, the hardness is higher, the turbine butterfly valve processed by ductile iron material is better than gray cast iron, and the service life is longer.

Second, cast steel material

Gray cast iron and ductile cast iron are generally used in low-pressure normal temperature pipelines, but if the medium pressure and temperature in the pipeline are relatively high, you need to use cast steel material, cast steel turbine butterfly valve, can be used in high temperature and high pressure environments, such as steam, oil media, it is more suitable.

Third, stainless steel material

Stainless steel has good anti-corrosion and anti-rust characteristics, so if the medium in the pipeline has a certain corrosion, you can use stainless steel turbine butterfly valve, and if the pipeline environment is easy to rust the metal environment, you can also use stainless steel turbine butterfly valve.

Fourth, aluminum alloy material

Aluminum alloy material has low water absorption, thermal insulation, corrosion resistance and other characteristics, aluminum butterfly valve used in the air conditioning cooling water system, can prevent condensation.

The above is to introduce the commonly used materials of turbine butterfly valve, turbine butterfly valve can be used for people's livelihoods, can also be used in the industrial field, industrial turbine butterfly valve can withstand high temperature, the applicable pressure range is also high, the nominal diameter of the valve is large, the valve body is made of carbon steel, the sealing ring of the valve plate is made of metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, mainly used in high temperature medium smoke duct and gas pipeline.
