ball valves have good points
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.
