Definition And Characteristics Of Stainless Steel Butterfly Valve

Definition and characteristics of Lined Butterfly Valve

Stainless steel butterfly valve refers to a butterfly valve whose valve body and valve plate are made of stainless steel (304, 316 material), and the seals are stainless steel seals and PTFE seals, that is, stainless steel hard seal butterfly valves and imported fluorine lined butterfly valves, which are corrosion-resistant, beautiful in appearance and long in service life. The stainless steel butterfly valves produced by Shangyu Group are suitable for regulating flow and intercepting medium in water supply and drainage, gas pipelines such as food, medicine, chemical industry, petroleum, electricity, textile, papermaking, etc. with a temperature of ≤150℃ and a nominal pressure of ≤1.6MPa. They are especially suitable for the switching and regulating of pipelines with corrosive media. .

The main features of stainless steel butterfly valves are:

1. Small and light, easy to disassemble and repair, and can be installed at any position. There are two connection methods: clamp type and flange type. It can also be equipped with flange shrinkage, called imported flange telescopic butterfly valve, which can prevent the extrusion of pipeline thermal expansion and contraction.

2. Simple and compact structure, 90° rotation and rapid opening. It can be powered by electric or pneumatic, called imported electric rubber lined butterfly valve and imported pneumatic butterfly valve, and remote control is implemented.

3. The operating torque is small, labor-saving and light.

4. The flow characteristics tend to be linear, and the adjustment performance is good. It can be used for adjustment.

5. The opening and closing test times are as many as tens of thousands of times, and the service life is long. 010-59430603

6. The seal can be replaced, and the seal is reliable to achieve two-way sealing, and the gas test leakage is zero. A stainless steel butterfly valve with a special structure can also be used, which can be used in high vacuum negative pressure places, called imported pneumatic vacuum butterfly valve.

7. The sealing material of stainless steel is stainless steel or high-quality fluoroplastics, which is resistant to aging and corrosion and can be applied to a variety of media.
