Various industries use valves for many different purposes in pipelines and production lines. In addition to monitoring flow and pressure, they can also measure stroke. Also, they can prevent hazardous issues by acting as protective equipment. Gases, fluids, or semi-fluids could be handled by valves. These elements are directed and regulated by them.
Valve types vary. Valve types include butterfly valves, globe valves, gate valves, cryogenic valves, check valves, and control valves. Furthermore, their materials can differ. Certain valves can be made of cast iron, while others can be made of stainless steel.
In understanding valves and their various types, the question arises: which of these valves are used in the chemical industry?
Various processes can be involved in the chemical industry. Electrical, hydraulic, pneumatic, and sometimes manual control mechanisms are used. It is important that the valves used can handle the pressure and prevent leaks. There are different functions associated with different valves.
1. Butterfly Valves
Butterfly valves are ideal for open/close actions that can be performed easily. Installation is easier, and they can work with a variety of actuators. Additionally, maintenance will not put a strain on your budget, since it is minimal.
A butterfly valve can also slow the flow of a substance. Additionally, they are lightweight. Additionally, they are very precise. Butterfly valves, however, can have poor sealing functionality, so if proper sealing is your primary concern, you might want to consider another valve.
2. Ball Valves
Chemical ball valves are another option. When the flow is low, chemical ball valves can be used. Gases and vapors can be handled by them. Ball valves come in single, split, three-piece, welded, and top entry styles.
In addition to forming a good seal, they are also known for their longevity. It is easy to open and close ball valves. In the chemical industry, chemical-resistant ball valves play a crucial role, along with other valves.
3. Gate Valves
The purpose of gate valves is to completely stop the flow of fluid. Alternatively, it can be operated in its fully open position. As a result, it can either be completely open or completely closed. In addition to parallel shapes, wedge shapes are also possible. Gate valves allow fluid to pass through a barrier by lifting it.
By using gate valves, the flow of substance is ensured to be uninterrupted. Another advantage of gate valves is that they take up as little space as possible in the pipe's axis.
4. Globe Valves
Manually operated globe valves can be ideal. They can also be used for automatic operations. It is possible to use them to regulate flow and pressure. Furthermore, they can be operated as completely closed or completely open valves. Two divisions are present on the inside of these sphere-shaped valves. Their movement is linear.
5. Check Valves
Chemical valves are another operator. Backflow can be an important consideration for a chemical check valve. As there is only one way through a check valve, the flow is usually unrestricted. If the flow turns in the opposite direction, the check valve will block itself to prevent damage to the other system. To prevent backflow, they are very important.
6. Plug Valves
The plugs inside plug valves can rotate to change the flow control. Conical and cylindrical shapes are most common. It is possible to stop or start the flow of fluid using the valves. Gas and fluid flow can be regulated within the system even at high pressures.
Plug valves are also considered cost-effective. Therefore, they are ideal for buyers who are concerned about their budgets. Natural gas is used in many households.
7. Actuated Valves
A 90-degree turn is required to shut off or open an actuated valve. A pneumatic valve, an electric valve, or a hydraulic valve can be actuated. As with the other valves described above, actuated valves have their own set of functions.
The valves are said to be adaptable to a variety of pipe systems. Actuator valves require low piping pressures.
With a wide variety of valves to choose from, they can be used in a variety of ways. They can be used for:
- Management of water
- Management of gas
- Processing of food
- Processing of beverages
- Power from nuclear sources
- Management of slurry
- Management of refineries
- Among other things, are biofuels.
Many systems rely on valves. As the chemical processing industry continues to grow, certain types of valves are in high demand. The industry relies heavily on butterfly valves, ball valves, gate valves, check valves, globe valves, plug valves, and actuated valves.
The many systems used to move fluids, gases, and semi-fluids all serve their functions and purposes, and every one of them plays an important role in their proper functioning and safety. If you would like more information or clarification on these valves, you can visit Dombor.
