wafer type butterfly valve

‌Is a common industrial pipeline valve, mainly used to control the fluid medium in the pipeline. Its characteristics include compact structure, small size, light weight, especially suitable for places with narrow space or short pipe spacing. The wafer type butterfly valve is connected between two pipe flanges through stud bolts, which is relatively easy to install and maintain.

 

Uses and features

Soft sealing butterfly valve is suitable for temperature ≤ 120 ℃, nominal pressure ≤ 1.6Mpa food, medicine, chemical industry, petroleum, electric power, textile, paper and other water supply and drainage, gas pipeline for regulating flow and intercepting medium. Its main features are as follows:

1. Novel and reasonable design, unique structure, light weight, rapid opening and closing.

2, the operating torque is small, easy to operate, labor-saving dexterity.

3, can be installed in any position, convenient maintenance.

4. The seal can be replaced, and the sealing performance is reliable to achieve two-way sealing and zero leakage. 5. The sealing material has the characteristics of aging resistance, corrosion resistance and long service life.
