Ball Valves

A Ball Valve is a quarter-turn rotational motion valve with a straight through design that uses a ball-shaped disk to stop or start flow. If the valve is opened, the ball rotates to a point where the hole through the ball is in line with the valve body inlet and outlet. If the valve is closed, the ball is rotated so that the hole is perpendicular to the flow openings of the valve body and the flow is stopped. Ball valves can be found in a number of different styles. Some of these include one-piece, two-piece, three-piece and lastly, what is referred to as flanged body construction. Each form of ball valve has its own good and bad points, all dependent on what each application calls for. Ball valves are made using an assortment of materials, some of which include brass, bronze, cast iron, copper ductile iron, metal alloys, stainless and other steel types, and plastics (including CPVC and PVC). Ball valves are to be found being used in a number of different industries. Some of these include the chemical, oil, pharmaceutical, allied process and also services such as corrosive, abrasive and cryogenic.
