6 Types of Flow Control Valves & What You Need to Know About Them

6 Types of Flow Control Valves & What You Need to Know About Them

Regardless of the industry you&#;re in, choosing the right type of valves for your application is essential for safety and customer satisfaction.

Installing and maintaining the proper valves may even be legally required.

Valves are an integral part of any pipeline system and a significant investment for businesses. It&#;s important that your engineers understand how all types of valves work.

How do you know which type of valve is best for your system? Keep reading to learn more about the most common types of flow control valves to help you make an informed decision. 

1. Ball Valves

Ball valves use a spherical plug design that contains a bored-in passage. You can operate these types of valves manually by using a lever, which also indicates whether the valve is open or shut, or automatically, by using an actuator.

This type of valve gives you excellent control of liquid flow through the valve and a secure shutoff when closed. They are often used in sewage treatment, chemical, and paper plants.

2. Check Valves

These types of valves prevent the reversal of fluid flow in piping.

Check valves remain open by the flowing fluid. If the fluid reversed, the valve will close. This type of valve includes lift checks and swing checks. 

3. Butterfly Valves

This type of valve is usually used in the oil and gas processing industries, for oil and gas transmission, in water and sewage plants, and in thermal and hydroelectric power stations.

They are commonly used because they are lightweight, easy to operate, they clean themselves, and there isn&#;t much pressure drop across the valve when it&#;s open. 

4. Gate Valves

Gate valves are best used as isolating or stop valves, where you want full flow or no flow.

When they&#;re fully opened, the fluid will flow in a straight line and there isn&#;t a significant drop in pressure because of a low resistance to flow. 

5. Globe Valves

Globe valves feature a unique construction designed to make the fluid passing through change direction twice.

They are ideal for throttling and regulating flow with wire drawing and seat erosion. They are cheaper than gate valves but have greater resistance to flow. 

6. Needle Valves

These types of valves offer precise control of flow. They feature a sharp pointed disc and a matching seat.

They are often used for chemical feed control services or continuous blowoff.

It&#;s worth noting that although needle valves can control flow with precision, they are usually capable of handling only relatively low flow rates. 

Purchasing These Types of Flow Control Valves

As you can see, the best types of flow control valves for your operation depend on your application.

Having a basic understanding of your options will ensure you make the right choice. Being informed will help you make the best decision.

A control valve is essential for industrial units with gas or liquid flowing through pipelines. The valve can handle various functions and is an integral part of your unit. How do I source these valves? The answer to this question is easy because there are plenty of control valve suppliers in India, and most have an online presence. Therefore, you could quickly come across suppliers of the product.

The top control valve manufacturers in India offer a varied product range, but you must not pick up anything randomly. Here are five essential factors you must consider while sourcing these valves.

1: What is flowing through the pipeline?

The characteristics of the material flowing through the pipeline should dictate the choice of control valves for your unit. Is the material flowing through the pipes rather harsh or corrosive? If the control valve has to deal with this flow, you must carefully select them. The PTFE or PFA control valves can be appropriate choices because they can handle such harsh conditions. Your control valve needs could be different for the flow of pressurized gasses through the pipelines. Metal control valves would be appropriate to take gas transportation through channels.

2: What will be the primary function of the control valve?

Why does your industrial unit need the control valve? The control valve can perform a broad range of functions, which is the second factor to consider when selecting a control valve. Here are some of the reasons why you may need a control valve.

• There could be a need to shut off the flow
• You might need a valve that can divert the flow
• Your unit could need a valve that can execute pressure relief functions.
• Backflow prevention could also be a reason why you might need a control valve
• Is there a need to adjust the flow within the pipeline? This is one more reason why you need a control valve.

A control valve can perform these functions, and you must select according to your needs. You can take the example of ball valves. They can resist clogging and jamming but are inappropriate for adjusting the flow. You must consider these aspects before selecting a control valve. The top control valve manufacturers in India will brief you on each product&#;s features and help you choose.

3: What is the performance capacity of the valve?

This is another factor to consider, as you are sourcing the product from India&#;s best control valve suppliers. What are the pressure and temperature requirements the valve is expected to perform? This is the information you will need before the buy. Metal valves will be appropriate if your operations are conducted in higher temperatures. Such control valves are also perfect for transporting pressurized gasses through pipelines. The inherent strength of metal makes them survive in harsh conditions. Plastic control valves can be considered when the requirements are not extreme.

4: Why should you Focus on sizing?

It would help if you focused on sizing when selecting control valves for your unit. An improper-sized valve can create operational problems for your team. A little control valve will create issues right away because it will simply not allow passage for the flow of liquid or gas via the pipeline. If you opt for oversized valves, there could also be problems. If there is a minor change in the valve position, it can lead to a significant difference in the flow. You might have to deal with friction problems for oversized valves. Therefore, sizing the valve is the fourth key factor to consider while buying them for your industrial unit.

5: What is the focus on the actuation method?

This is the fifth factor to consider when selecting control valves for your industrial unit. How will the valve be operated? If the valve is manually operated, it should not be an issue, but if you need actuation, you will have to select after careful observation. Your unit will require a pneumatic, electric, or hydraulic actuator for the latter.

Conclusion:

These are the five essential things you must consider while selecting control valves for your unit. You can source your product from the top control valve suppliers in India, who will guide you at every stage. Discuss your needs with them, and they will show you the control valve you need for your unit.
