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 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
• Plug Valves
• Butterfly Valves
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. They are suitable for high-pressure and high-temperature 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.
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 leading butterfly valve supplier, It is most suitable for ship-building and food processing applications.
