Ball valves are flow valves that are quarter-turn and straight through apparatuses. These valves allow for shut-off and/or purposes of control. They have a round closure element that contains a matching pair of rounded seats. These seats allow necessary sealing to take place. The ball valve pressure rating and materials used determines what kind of seat is required. Not all valve seats are the same. Some are of the single molded variety while others have higher- pressure ratings, which often include a design known as a "trunnion." This design means that each ball valve face is sealed separately, not together. Ball valves have many good points and are often considered superior to many other kinds of valves. Ball valves are very easy to use and can both maintain and regulate three things-high pressure, high volume and high flow of temperature. Other advantages of ball valves are that they are sturdy devices that can be purchased for a low price and they have a long service life. An added plus is that the regulating element's design makes it easy for the ball valve to work without concern about side loads, which often plague globe or butterfly valves. The ball valve design allows for the easy ability to fix the seats if a problem arises and also seals without having to take away the body of the valves from the line. 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 and cryogenic.
