There are various types of materials for turbine butterfly valves. This article will only introduce you to the common ones.
1.Grey and ductile iron material
These two materials are mostly used in water system pipelines, but there are some differences between the two. The spheroidization rate of ductile iron is higher and the hardness is higher. The quality of turbine butterfly valves made of ductile iron is also higher than Grey cast iron is better and lasts longer.
2.Cast steel material
Gray cast iron and ductile iron are generally used in low-pressure and normal-temperature pipelines, but if the medium pressure and temperature in the pipeline are relatively high, cast steel materials are required. Turbine butterfly valves made of cast steel can be used in high temperature and high pressure environments, such as Steam and oil media are more suitable.
3.stainless steel material
Stainless steel has good anti-corrosion and anti-rust properties, so if the medium in the pipeline is corrosive to a certain extent, stainless steel turbine butterfly valve can be used, and if the pipeline environment is easy to cause metal corrosion, stainless steel can also be used. material turbine butterfly valve.
4.Aluminum alloy material
Aluminum alloy material has the characteristics of low water absorption, thermal insulation, and corrosion resistance. Aluminum butterfly valves are mostly used in air conditioning cooling water systems to prevent condensation.
he above are the commonly used materials for turbine butterfly valves. Turbine butterfly valves can be used for people's livelihood and also in industrial fields. Industrial turbine butterfly valves can withstand high temperature and have a high applicable pressure range. The valve has a large nominal diameter and the valve body adopts Made of carbon steel, the sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high temperature butterfly valve is made of steel plate welding, mainly used for flue air duct and gas pipeline of high temperature medium.
