Stainless steel butterfly valve, also known as stainless steel flap valve, adopts three eccentric multi-layer metal hard seal structure; Stainless steel butterfly valve is widely used in metallurgy, electric power, petrochemical, water supply and drainage and municipal construction industries where the medium temperature is ≤425℃ On the pipeline, it is used for adjusting the flow rate and carrying and breaking the fluid. The stainless steel butterfly valve adopts a triple eccentric structure. The valve seat and the sealing surface of the disc plate are made of different hardness and stainless steel, which has good corrosion resistance and long service life.

Stainless steel butterfly valve, as a component used to realize the on-off and flow control of the pipeline system, has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. But because of the Stainless steel butterfly valve
Due to the limitation of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance.
1) The Stainless steel butterfly valve is convenient to open and close quickly, saves effort, has low fluid resistance, and can be operated frequently.
2) Stainless steel butterfly valve has simple structure, small size and light weight.
3) The Stainless steel butterfly valve can transport mud, with the least accumulation of liquid at the pipe mouth.
4) The stainless steel butterfly valve can achieve a good seal under low pressure.
5) Stainless steel butterfly valve has good regulation performance.
1) Stainless steel butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type and lever type according to the structure.
2) Stainless steel butterfly valve can be divided into two types according to the sealing type: relatively sealed type and hard sealed type. The soft seal type generally uses a rubber ring seal, and the hard seal type usually uses a metal ring seal.
3) Stainless steel butterfly valve can be divided into flange connection and wafer connection according to the connection type;
4) According to the transmission mode, Stainless steel butterfly valve can be divided into manual, gear transmission, pneumatic, hydraulic and electric.
