Understanding how a ball valve works is very simple. It is usually designed with a large drilled hole that runs from one side to the other through the center. The ball fits snugly into the base inside the pipe opening (port). It is attached directly to the valve's operating handle, which is usually located above or to the side of the device, usually on the outside of the piping assembly. By turning the handle, usually a quarter turn to 90 degrees, the ball rotates about its axis within the port.   This action aligns the hole in the sphere with the direction of flow of the media in the pipe, allowing it to  pass freely through the ball valve . This is referred to as the open or open position. Turning the handle back 90 degrees in the other direction, closed or off, rotates the ball so that the hole through it is perpendicular to the direction of flow. At this point, the medium can no longer pass through the ball valve and the flow is completely blocked.   Application of ba...

Ball Valves A ball valve is a valve that uses a hollow, rotating ball to cut off, distribute, and redirect the flow of media in a pipeline. It can also be used for fluid regulation and control. Ball valves provide very good shutoff capability. A simple quarter turn (90°) is all it takes to open or close the valve. If the hole in the ball is in line with the flow rate, the valve opens, and when the ball is rotated ninety degrees using the valve handle, the valve closes. This feature minimizes valve operating time and reduces the potential for leakage due to gland seal wear.   The primary function of a ball valve is to isolate parts of a piping system by starting, stopping or regulating the flow of media (usually water, air or gas) between different chambers, pipes and ducts. This is accomplished by allowing the media to pass freely through the ball valve, by allowing the media through a narrow opening section, or by stopping the flow altogether. Depending on the valve type and handl...
