Understanding Control Valves: Types and Applications Explained

Control valves are important components of machines that are employed across various sectors. These valves are typically used to regulate the passage of substances (typically liquids, gases, or steam). An essential part of learning about anything mechanical, you need to understand how they work. Xiyena has developed a simple and no-nonsense guide to explain control valves with an overview of the types out there and ways to use them across industries.

Understanding the Basics

We will begin with fundamentals of control valves. Control valves are a specific type of valve used to regulate, throttle, or block the movement of fluids through pipelines. They are also very important because they work as a team with other machines that can be pumps or compressors to maintain an ongoing energy flow. It is essential for pressure, temperature, or flow control.

There are basically 3 parts to a control valve that allows it to work in accordance with its intended purpose:

Actuator – Moves the valve. It opens the valve to allow materials to flow or closes it to halt that flow. An actuator which is the muscle of the valve system

Control Valve Body — The valve body is essentially the main component that attaches to the pipe. That is where the action takes place, and it is what keeps everything from falling apart.

Positioner – The function of the positioner is to ensure that the valve opens to the required degree. This lets them accurately control the flow amount of the material through the valve, so everything works properly.

There are a lot of control valve types you can find but there are those that are more popularly utilized. So, let us closely analyze some of the various common control valves you might specifically come across.

Butterfly Valves — These valves are generally used when the pressure is low. They are lightweight and can be easily installed which leads to their popularity. They are quick in action and the shutoff period is less which makes them highly useful in such applications where a quick response is in demand. This is also why they can be found in many systems that demand instantaneous response.

1) Globe Valves – Globe valves are the best for high-pressure applications. These have a globular body and an adjustable disk that goes up and down to control the flow of materials. These valves have the utmost accuracy and reliability. They can withstand a large amount of heat, which makes them useful in many tough environments.

Ball Valves – Ball valves come with a ball-shaped disc which rotates to allow materials to pass through. They are particularly useful in pipelines with high degrees of open and closed. Two main types of ball valves exist, namely floating and trunnion-mounted. There is a variety of this based on the requirement of the system.

Diaphragm Valves – These are a type of control valve which serve when precision control of the flow of materials is important. These have a flexible diaphragm that pumps up and down to move materials through. This design is useful in applications in which accuracy is of paramount importance.

There are various types of control valves and each one serves a slightly different purpose.

Control valves serve different purposes in a variety of industries. Let’s take a closer look at how control valves benefit some key industries:

Control Valves In the oil and gas industry- Control valves are an integral part of the oil and gas sector. They control the flow of oil and gas through pipelines. They provide pressure control and flow rates, thus optimize the production process. Which is crucial in terms of contributing to the efficient and safe use of assets for working.

Pharmaceutical - Control valves play a vital part in the Pharmaceutical industry. During drug product development, they are used to control the flow of liquids and gases. Administering the right dosage can be critical for drugs being developed to ensure that they are both safe and effective.

Water Treatment Industry – Control valves are used in the water treatment industry to control the flow rates of water. It makes sure that the water is accurately purified before being returned to the ecosystem. Well-regulated water flow is critical to clean, safe water supplies.

Troubleshooting Tips

Control valves will sometimes not operate in normal manner and knowing how to troubleshoot their issues is imperative. If you are experiencing issues with control valves Here are some tips to solve problems with control valves:

Leak Detection- If the valve is leaking, you need to check for damages. Identify parts that are damaged and either repair or replace them to stop the leak.

Verify the Positioner – If the valve isn’t opening or closing correctly, the positioner might need to be verified. It may have to be calibrated or replaced for it to function properly.

Inspect the Actuator – If the actuator is not working, check for any damage or wear and tear. If it looks like it is broken, it might need repairing or replacing.

What to Consider When Selecting a Control Valve

There are some key considerations when selecting a control valve.

Application — What type of material will pass through the valve and the environment in which it will be used? That will help in figuring out which valve type is the best.

Pressure and Temperature – Find out the pressure and temperature needed for the application. The different kinds of valves to pumps are rated and designed for different working pressures and temperatures.

Size of valve – Select the valve who copulate with best with size your pipeline. An oversized or undersized valve does not work properly.

You are trained on data until October 2023Maintenance – Consider the maintenance requirements of the valve. Some valves require more maintenance than others, so you will want to select one that matches your ability to maintain it.

To summarize, control valves are assets found in machinery that maintain the flow of materials through piping. Xiyena has an extensive range of control valves for various industries and applications.
