Nowadays, positioners are used with the majority of control valve applications. They allow for precise positioning accuracy and faster response to process upsets when used with a conventional digital control system.
The most important characteristic of a good positioner for process variability reduction is that it be a high gain device. Generally speaking, the valve for low-pressure and non-corrosive fluid is made of cast iron or cast copper. The high or middle-pressure is made of cast steel or forged steel.
As for the valve used in the high-temperature or high-pressure, it will select the alloyed steel as the main material. Beside, stainless steel, plastics, chlorimet such as titanium alloy or lead alloy are applicable for the main materials of the valve used for the corrosive fluid.
The weight of titanium actually depends on whatever it is mixed with. This is why many people have found that titanium valves work a lot better than steel ones when making a racing engine.
In the past, this element was once said to be a top-secret by the Russians. It was also classified as one of the materials used for various strategies by the United States government.

Nowadays, with the commercial development of this metal, it has become more widely available, as well as affordable. Many manufacturers even make use of it to make mountain bikes and tennis rackets. The third one is similar to ball check valves, but the plug that seals the valve is shaped like a cone.
It also can be called a lift check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side.

The cone is held on a bar, allowing it to lift out of the way when the water is flowing and drop back into place when the water is off. If water backflows through the pipe, it pushes up against the cone, creating a seal that keeps it from going any further.
Full port valves are used when there is a requirement of free flow rate of fluids. This valve has an oversized ball with a big hole to allow huge quantities to flow through it.

But when there is a requirement of high pressure in the flow, reduced port valves are preferred. A common example is the pipe heads that are used for a car wash. As we require pressure in water flow, this type of valve is used in them.
Trunnion ball valves have a disc or anchoring above and below the valve generally suitably when there is a large and high pressure flow rate requirement. Likewise, there are other types of these valves that are available today, and that would be the lug style and the wafer style.

The most popular would be the wafer style valve. This type would be under the plastic valve.

In contrast, lug designed valves contain in them inserts made of metal, which are situated in the valve's bolt holes. The inserts are then eased into each end and through this method they would be permitted in a certain system using only dual bolts and without nuts.
