What are ball valves



Generally, valves are devices used to control the flow of a gases or liquids through a closed tube or pipe system. Flow through a valve can be relatively unobstructed when it is completely open. Flow stops when the valve is completely closed.

A ball valve consists of a valve body with a rotatable ball in it. This ball or sphere has a hole or bore through its center. The handle on a ball valve opens the valve when it turns the ball to align with the pipe or tube so that it is pointing the same direction as the pipe. This allows flow to pass through it. The valve handle can also turn the ball so that the bore is at a right angle or 90 degrees to the flow. This closes the ball valve.

Ball valves are tough, durable and reliable. They close securely even after long periods of not being used. These qualities make them an excellent choice for shutoff and control applications. Ball valves are unable to provide fine flow control or throttling. Gate, globe or needle valves are more appropriate for these situations.
