Different Types of Control Valves and Their Applications.


Control valves are devices that regulate the flow of fluids in various industrial processes. They can control the flow rate, pressure, temperature, or level of the fluid by opening or closing partially or fully in response to a signal from the controller. Control valves are essential for optimizing the performance, efficiency, and safety.

There are many types of control valves available in the market, each with its own features, advantages, and disadvantages. Choosing the right type of control valve for a specific application depends on several factors, such as:

• The type and properties of the fluid (liquid, gas, steam, etc.)
• The operating conditions (pressure, temperature, flow rate, etc.)
• The desired control action (on/off, throttling, etc.)
• The required accuracy and reliability
• The available space and budget

You can also get the best control valves from an experienced valve suppliers or control valve suppliers. Let us see some of the most common types of control valves and their applications.

Rotary Control Valves

Rotary control valves are valves that use a rotating element to control the flow of the fluid. The rotating element can be a ball, a disc, or a plug that fits into a seat or an opening in the valve body. Rotary control valves are typically used for on/off or throttling applications where fast and precise control is needed.

Some examples of rotary control valves are:

Ball valves: Ball valves have a spherical ball with a hole in it that aligns with the flow path when open and blocks it when closed. Ball valves are simple, durable, and easy to operate. They provide excellent sealing and low head loss. As opined by leading Ball Valves supplier, They are suitable for high-pressure and high-temperature applications.

Butterfly valves: Butterfly valves have a disc that rotates around a central axis to regulate the flow. Compared to other valves butterfly valves are cost efficient, smaller in size, and require less maintenance. As opined by a leading butterfly valve supplier, It is most suitable for ship-building and food processing applications.

Plug valves: Plug valves have a cylindrical or conical plug that rotates inside the valve body to control the flow. Plug valves can withstand extreme pressure and temperature conditions and provide tight shutoff. They are suitable for oil piping systems and corrosive media applications. However, they cannot be used in throttling applications and may require lubrication.

Linear Control Valves

Linear control valves are valves that use a linear motion to control the flow of the fluid. The linear motion can be achieved by a stem that moves a plug, a diaphragm, or a piston into or out of a seat or an opening in the valve body. Linear control valves are typically used for throttling or modulating applications where precise and accurate control is required.

Some examples of linear control valves are:

Globe valves: Globe valves have a plug that moves up and down inside a spherical valve body to regulate the flow. As explained by a Globe valves supplier, it offers good control performance and can handle high-pressure drops and high-temperature fluids. They are suitable for wastewater plants, power plants, and process industries etc. A highly experienced and reputed globe valves supplier can provide you the best globe valve that meets your specifications.

Diaphragm valves: Diaphragm valves have a flexible diaphragm that moves up and down to adjust the flow area. Diaphragm valves are ideally suited for corrosive applications where the body and diaphragm materials can be chosen for chemical compatibility. They are also suitable for abrasive applications where the body lining can be designed to withstand abrasion and the diaphragm can be easily replaced.

Conclusion:

In conclusion, control valves play a vital role in industrial processes by regulating the flow of fluids. The choice of control valve depends on factors such as the fluid type, operating conditions, control requirements, accuracy, reliability and more.

Factors to Consider in 2024 While Selecting Industrial Valves for Your Application

Image
In the domain of industrial functioning, choosing valves which are perfect for your application is as important. Indeed, the valves are responsible for regulating flow, pressure or redirecting movement of fluids and gases. Industrial valves are a key factor in maintaining smooth operations. Heading into 2024, the valve technology landscape is in constant flow with many choices, which make it a difficult task for the business to do and there are lots of aspects to take into account to make the best choices. We will begin our discussion with the vital points that must be taken into account when choosing industrial valves in 2024. Application Specificity : First of all, be careful about your application’s specific features. Different industrial processes also need different types of valves. For example, when exact control of the valve is required, globe valves may be appropriate. On the other hand, gate valves are generally used in processes requiring a 100% flow or a complete shut-off.
