Stainless steel butterfly valve (also known as stainless steel flap valve) adopts three eccentric multi-layer metal hard seal structure, which is widely used in metallurgy, electric power, petrochemical, and water supply and drainage and municipal construction and other industrial pipelines for medium temperature ≤ 425 °C. Flow and loading fluid use. Next Xiaobian introduced stainless steel butterfly valve features and stainless steel butterfly valve classification.
Stainless steel butterfly valve features
1, small and light, easy to disassemble and repair, and can be installed in any position. There are two types of clips and flanges. Can also be equipped with flange shrinkage, called the import flange type retractable butterfly valve, can prevent the thermal expansion and contraction of the pipe extrusion.
2, the structure is simple, compact, 90 ° turn quickly open. Can add electric or pneumatic, known as imported electric rubber lined butterfly valve and imported pneumatic butterfly valve, implement remote control.
3, the operating torque is small, effortless and light.
4, flow characteristics tend to straight line, good regulation performance. Can be used to regulate the effect.
5, the number of opening and closing test up to tens of thousands of times, long life.
6, seals can be replaced, sealed and reliable to achieve two-way sealing, gas test leak is zero. Specially designed stainless steel butterfly valves can also be used, which can be used in high-vacuum vacuum locations, known as imported pneumatic vacuum butterfly valves.
7. The stainless steel sealing material is made of stainless steel or high-quality fluorine plastic. It is resistant to aging, corrosion, and can be applied to a variety of media.
