Electric ball valves are mainly used for gas, petroleum, air and water, etc. Due to advantages, electric ball valves have a wide scope of application. 

 

Main advantages of electric ball valves:

1. Electric ball valves can realize full sealing in a wide range of pressure and temperature;

2. Medium can be sealed reliably on the sealing faces of valve;

3. Electric ball valves can sustain stress from pipe;

4. The valves can realize rapid on-off;

5. The ball can locate automatically in its position.

 

Electric ball valves are not only widely applied in petroleum, gas, chemical engineering, water treatment, but also used in cooling water system in thermal power station. Electric ball valves in common use include wafer electric ball valves and flange electric ball valves. Wafer electric ball valves are connected with two flanges on pipe by using studs. Flange electric ball valves have flanges on two ends. The valves are joined with flanges on pipes. Strength properties of valves refer to the performance that valves sustain pressure of media.
