Facing any challenges in industrial flow control needs one solution– that is valve. Numerous types of valve products are available in the market. Different industries face different challenges, so choosing the right valve products for your system is a must. As per your industry need if you choose the right valve product,it can ensure safety, operational efficiency and long-term reliability. 

Each application (oil & gas, water treatment, chemical processing, HVAC) requires specific, tailored valves. In this blog, we will share the basic ideas or a step-by-step guide that helps you choose the right valve product as per your needs:

1. Define Your System Goal

You need to completely understand your industry needs. Do you want to start or stop the flow, control pressure, prevent backflow or regulate flow rate? Choose your basic needs; these functions directly help you to select the right valve. For e.g., for quick shut-off, you need ball valves, for backflow prevention check valve is the right product and for throttling globe valve is the best option. 

2. Understand the Composition of the Fluid 

Secondly, you need to figure out which guild will pass through the valve!? For e.g., water, gas, oil, chemicals, or slurry. The nature, pressure and temperature of fluid can determine the right valve solution. Here are some examples: 

• Stainless steel valves are a perfect solution that can resist corrosion and are ideal valve solutions for chemical processing.
  
• Brass valves are mostly used for water, wastewater and non-corrosive fluids.
  
• Plastic or PVC valves are mostly used for low-pressure and non-corrosive systems.
  

3. Check your system pressure & Temperature Range

Each valve product is rated for specific pressure and temperature ranges. You have to ensure the valve that you have chosen that need to complies with your system’s maximum operating pressure (PSI) and temperature range. Exceeding their limits lead to reduced lifespan, failure and leakage problems. Select the right valve products according to your system pressure and temperature. 

4. Select the Valve Type Based on Use Case

Each valve comes with their unique advantages. Here is the quick overview that shows their uniqueness:

• Gate valves - They are ideal products for full open and close flow control.
• Ball valves - They are ideal product for low maintenance and pressure drop and as for quick shut-off.
• Check valves - They are ideal to prevent backflow in pipelines.
• Globe valves - They are excellent to regualte flow.
• Butterfly valves - They come in lightweight and compact designs so these valve are ideal for large flow volumes.
• Control valves - They are ideal product that protect against over pressure situations.

You can find the right valve type to the Duncan’s flow requirements of your application.

5. Select Valve Size Accordingly and calculate Flow Rate

Valve size matters because it is not just about matching pipe diameter but it’s about understanding flow coefficient and also how the valve behaves under various flow conditions. Choosing the right size valve is mandatory because undersized valves can restrict flow, while oversized reduce efficiency of flow. To choose the right product you can consult with an expert engineer or use flow simulation tools. 

Final Thoughts

Choosing the right valve solution is not only about one-size fitting. It involves many factors such as flow rate, temperature, pressure, media, application and other control methods. All above five points can help you to make the right selection and ensure long-lifespan of your system and optimal performance. Right valve products can also reduce maintenance and boost overall efficiency.
