A ball valve has a spherically shaped disc, the valve’s part which monitors the flow through it. A hole or port is composed in the sphere through its middle; the purpose is for flow to take place when the port is in line with the two ends of the valve. Subsequently, flow is blocked as the hole becomes perpendicular to the ends of the valve at the close of the valve. The valve’s position can be seen as the lever or handle will be in line with the position of the port.

The kind of seat required is dependent on materials used and the pressure rating. All valves seats are not the same; while some are of single molded variety, others are of high pressure ratings. The trunnion design is among the higher-pressure rated and indicates that the face of each ball valve is not together but separately sealed.

Even after many years of use, ball valve still work to accomplish perfect shutoff; they are durable in nature. If you are therefore looking for the best valves for shut off applications, these valves are the best suited; in the context of shutoff applications, they suit perfectly and better in comparison with the globe valves and gate valves. However, they do not achieve the fine control needed in throttling applications, although they can be sometimes used for such purpose.

Because of their versatile nature, ball valves are widely used in industry; they support pressures of about 700 bars temperatures reaching to 2000C. These valves are sized between 0.5 cm and 30 cm. The procedure of operating and repairing the valves is quite easy. These valves can compose of metal or plastic body; or metal with a ceramic center while the ball is usually chrome plated to enhance its durability. They belong to the family of quarter turn valves along side with plug valve and butterfly valve.

These types of valves are good in many respects; they are usually seen as being superior relative to some other kinds of valves. They function to maintain and regulate 3 basic things; high volume, high pressure and high flow of temperature. These devices can be beneficially purchased at lower price. Their regulating element’s design aids their functioning without bothering about side loads; also, its design gives room for easy fix of the seats in problematic situations and also seals with the body of the valves in the line.

The ball valves are supported by elastomeric cushions that supply pressure against the ball and also make provision for wear. As noted earlier, these types of valves work to achieve complete shutoff irrespective of the number of years they have been in use. They are the preferred types of valves for shutoff applications; but they might function effectively as well in throttling applications.

There are other kinds of valves such as safety valves, butterfly valves, choke valves and many others. Each one is used for one or more application that it fits in. Ball valve is perfectly fitted for shutoff applications.
