What is an API Ball Valve?

1. What is an API Ball Valve?

API ball valve is designed and manufactured in API 6D & API 608, which is mainly used on the pipeline to cut, distribute and change the direction of medium flow. The working principle is to make the valve unblocked or blocked by rotating the valve.

 

2. The Strengths of API Ball Valve

API ball valve is widely used in different industries for its multiple strengths, such as reliable sealing, simple structure and convenient maintenance. And the sealing surface and spherical surface are often in a closed state, which can not easy to be eroded by media. Besides, the ball valve switch is light and small.
