Brief Introduction of Ball Valve
2020-02-13

Ball valve is a kind of valve that uses a ball with a circular channel as the opening and closing parts, and the ball rotates with the valve stem to realize the opening and closing action. We supply various trunnion mounted ball valve,floating ball valve,fully welded ball valve and other multi way ball valve.


Ball valve is evolved from plug valve. They have the same 90 degree rotation action, the difference is that ball valve has a ball with circle port, while plug valve has a plug in the shape of cylindrical or conical. In a cylindrical plug, the channel is generally rectangular; in a conical plug, the channel is trapezoidal.


The main feature of ball valve is its compact structure, easy to operate and maintain and suitable for not only general working media such as water, solvents, acids and natural gas, but also for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. Besides, ball valve body can be integrated or combined. Generally speaking, ball valves are most suitable for directly opening and closing, but recently, ball valves have been developed and designed to throttle and control flow. Ball valves are one of the most supplied valves at dvsvalve.com.
