The ball valve is usually equipped with 90-degree turn handles, which are very fast. In these valves, a ball valve is typically used to control the flow to give easy on-off control. The operators control ball valves, and they are usually easier and faster to operate than gate valves.
Compact butterfly valves are typical of butterfly valves. They serve as a quick-acting rotary motion valve. We can also say that butterfly valves are ideal for tight spaces because of their wafer-type design. Many different configurations are possible with butterfly valve bodies.
Backflow is mainly prevented with check valves. These valves are self-activated, where they allow the valve to automatically open when media passes through the valve. Here the media passes through the valve in a particular direction and then closes.
Gate valves are usually included in the most common types of valve systems. They typically use linear motion to stop or start the flow. Gate valves are used for flow regulation but they are not used for flow control. Gate valves are used primarily in the fully open and closed positions.
Knife Gate valves are different from other types of valve systems and are usually used to control media flow containing solids. In knife Gate valves, a thin gate is present, which controls through linear action. Then these valves cut through the materials and create a seal.
It is to note that knife Gate valves are not best for high-pressure implementations. They are usually ideal for oils, paper, pulp, slurry, wastewater, grease, and other media.
Most commonly, globe valves are used and applied to control operations. Globe valves come in three types of body, including the Y-pattern, the T-body, and the angle body.
As the name depicts, needle valves are typically used in small diameter piping systems. They are required in situations where accurate flow control is needed. They get their name from the narrow point in the conical disc used within.
Slurries, liquids containing suspended solids, or solids in suspension are handled by pinch valves. While flowing, linear motion is used in these pinch valves. Additionally, these valves contain internal sleeves that isolate the media.
Typically, plug valves control the flow of fluid by utilizing cylindrical or tapered plugs. To maintain the flow, they use a quick-acting quarter-turn valve handle. They are mainly famous for giving tight shutoff and also very effective in high-temperature or high-pressure environments.
As the name depicts, pressure relief valves are used in those areas where there are overpressure events. So they are accommodating in increasing safety by using automated spring valves. By decreasing the pressure, they will therefore return the system to the desired pressure. Our discussion has been on the functionality of valves, not on their designs. The standard design types of different valves with their standard functional designations are as follows:
There are many types of valves in isolation valves, such as pinch valves, Gate valves, diaphragm valves, ball valves, butterfly valves, Piston valves, and plug valves.
Regulation valves include diaphragm valve, needle valve, Ball valve, butterfly valve, globe valves, pinch valves, and plug valves.
Safety relief valves include vacuum relief valves and pressure relief valves.
Check valves for lifting and swinging are among them.
These include float valves, foot valves, multiport valves, the line behind the valve, and the knife Gate valve.
