5 Things to Know Before Buying control valve is

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.

Valves are used to handle a wide variety of functions in controlling the flow of liquids and gases. With so many options available, it’s important to look at all of the factors to ensure you are selecting the correct valve for your application.

1. Media Type

The characteristics of the liquid or gas type being controlled will determine the valve material that should be used. When monitoring harsh or corrosive materials, polytetrafluoroethylene (PTFE) and perfluoroalkoxy alkanes (PFA) are great choices, as they are able to withstand these conditions. When monitoring pressurized gases, it’s important to use metal valves for the highest level of safety.

2. Application Conditions

The selection of the correct valve sizing is the most important step in selecting the right valve for your application. An improperly sized valve can cause operation issues within the valve or elsewhere in the system. In addition to this, determine the temperature, pressure, and flow rate that your valve will be operating under. In most cases, metal valves can withstand higher temperatures and pressures than plastic ones.

3. Valve Function

Determine the need that your valve needs to fill. 2-way valves perform well for on/off control in a system, while 3-way valves can be used for on/off control, as well as for diverting or mixing media. Also, take note of whether your valve will be open or closed the most often. In order to extend the life expectancy, order a valve that is normally in that orientation and changes to the other direction when energized.

4. Actuation Method

Another consideration to be made is how the valve is to be operated. Identify if the valve will be manually hand-operated or if the valve will need to be actuated to turn off and on automatically. If the latter is chosen, decide whether the unit is going to be used with an electric, pneumatic, or hydraulic actuator.

5. Maintenance Requirements

If maintenance needs to be done regularly, ball valves are a great option as they resist clogging and are one of the simplest valve types to service. Ball valves are also available in 3-piece configurations, which consist of two end caps and a body. This allows the main body section to be easily removed for cleaning without disconnecting the end caps from the pipe, preventing the line from being shut down during maintenance.
