Butterfly valves can be divided into pneumatic butterfly valves, electric butterfly valves, manual butterfly valves, etc. Butterfly valves are a kind of valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and regulate the fluid channel. The characteristics of the industrial butterfly valve are that it can withstand high temperatures, has a high applicable pressure range, has a large nominal diameter, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used in flue ducts and gas pipelines for high-temperature media. Read More
