1. Sealing performance of sanitary pneumatic butterfly valve:

Sanitary Butterfly Valve belongs to the mid-line stainless steel soft-sealed butterfly valve. Its sealing principle is that the valve plate is processed to ensure that its sealing surface has a suitable surface roughness value, and the synthetic rubber valve seat forms a suitable surface roughness value of the sealing surface during molding. When the stainless steel butterfly valve is closed, the outer cylindrical sealing surface of the valve plate squeezes the synthetic rubber valve seat through the rotation of the valve plate, so that the synthetic rubber valve seat produces elastic deformation elastic force as a sealing pressure ratio to ensure the sealing of the valve.

2. Characteristics of sanitary pneumatic butterfly valve

1. The rubber sealing ring and valve plate are both imported parts, which ensures the performance and use of stainless steel butterfly valves

2. The valve body is finely turned by a high-precision CNC lathe to ensure the reliable interchangeability of stainless steel butterfly valves, eliminating the trouble of not being able to ensure its performance due to replacement of rubber.

3. The valve stem is inlaid with nylon sleeves, which reduces friction and is flexible and easy to open. The steel parts are all made of stainless steel, and the rubber is made of food rubber, with high hygienic quality.

4. The valve body diameter is equal to the inner diameter of the pipeline. When opened, the narrow and streamlined valve plate is consistent with the direction of the fluid, with large flow and small resistance, and no material accumulation. The handle adopts the pull type and the pull type, which can withstand large operating torque and is not easy to break.

5. The opening and closing range is 90 degrees, which can be fixed at every 15 degrees. It is adjustable, and the opening and closing are fast and easy to operate.

6. The valve body adopts detachable connection, simple structure and convenient maintenance.

7. The shape is light and beautiful, the surface is bright and dust-free, and there are no burrs.

8. After rigorous strength and sealing tests, the quality is guaranteed.

9. The fatigue life test of not less than 30,000 times is carried out on sampling to ensure its service life.
