You can use different valves in product packaging technology, the pharmaceutical industry, food and beverage markets, and even the oil and gas industry. You often take valves for granted, and your life depends on them without thinking about it.
Whether you need high or low pressure or vacuum conditions, valves can accommodate them. They control the flow of gases, liquids, and steam.
So, what are the types of valves? Are there specific criteria you must take into consideration when choosing them? Let’s see all the details to understand everything about valves.
Introduction to Valves and Their Applications
Valves are critical components of fluid systems, and many valve types are available to meet the specific needs of different applications. You can categorize these valves into three main types–manual, automatic, and pneumatic valves.
- Manual valves are those operated by the user with a lever, wheel, or handle.
- Automatic valves are self-actuated and controlled with the help of a pressure difference, liquid, or gas.
- Pneumatic valves operate with pressure from a pressurized gas and have various applications in industrial setups.
Valves are also classified based on the flow pattern – stop valves, check valves, regulating valves, safety valves, quick-opening valves, etc. Depending on the nature and complexity of the fluid system, you can use any or several types of valves.
You can identify valves by their valve tags. It prevents anyone from using the wrong valve. It is critical to select the correct type of valve for a particular application to ensure safety and optimal performance.
Classification of Valves by Movability of Parts
There are two types of valves as classified by the movability of parts. They are rotary valves and linear valves.
Rotary valves are usually defined by their construction. You can determine linear valves by their operation in which a linear element provides a controlled passage.
Rotary valves are the most common type; you can subdivide them into two types. These are the globe or stop valves and the plug, butterfly, or ball valves.
Linear valves include gates, poppets, and sliders. The latter type is an electronically-actuated version of the former two. Generally, you can distinguish rotary and linear valves by their geometry, function, and closure device.
When to Consider Replacing Existing Valves
When replacing your existing valves depends on different factors such as age, leaks, corrosion, cost, availability, and condition. If you find any of these signs of deterioration, consider a replacement.
Furthermore, a new valve might be wise if undertaking extensive pipe renovations or upgrades. You should replace the valve if it is leaking or does not turn smoothly.
