Ball Valve
- Aug 30, 2018 -

Ball valves are evolved from plug valves.It has the same rotation 90 degree lift motion, different is the plug body is the sphere, has the circular through-hole or the channel through its axis.The ratio of the spherical surface to the inlet port should be such that when the ball rotates 90 degrees, all of the spherical surface should be present at the inlet and outlet, so as to cut off the flow.

Ball valves can be closed tightly with just 90 degrees of rotation and very little torque.Fully equal body cavity provides medium with little resistance, straight flow channel.Ball valves are generally considered to be most suitable for open and close use, but recent developments have designed ball valves for throttling and controlling flow.The main features of the ball valve are compact, easy to operate and maintain, suitable for water, solvent, acid, natural gas and other general working medium, and also suitable for working conditions of medium, such as oxygen, hydrogen peroxide, methane and ethylene.Ball valve body can be integral or combined.
