Butterfly valves are widely used in industrial applications for their reliability and efficient flow control capabilities. When it comes to demanding environments where space and weight requirements are critical and flow capacity is required, high-performance butterfly valves are the go-to solution. In this blog, we will explore the top six attributes to consider when selecting a high-performance butterfly valve to ensure the best performance and reliability in your applications. 

1. Chemical Compatibility and Resilient Seating: 

High-performance butterfly valves are designed to withstand aggressive chemicals and corrosive fluids. Look for valves with seats made of PTFE or metal alloys, which provide excellent chemical resistance. Unlike elastomers used in general service butterfly valves, PTFE or metal alloy seats can handle chemically reactive liquids, gases, and low-pressure steam without erosion or degradation. This feature ensures long-term sealing integrity and prevents leakage in demanding applications. 

2. 
Extended Size Range for Versatility: 

High-performance butterfly valves offer a broader size range compared to general service valves, making them suitable for both small and large applications. With sizes up to 108 inches, these valves can accommodate a wide range of flow requirements. Whether you need precise control in a small pipeline or efficient flow management in a large industrial system, high-performance butterfly valves provide the versatility you need. 

3. 
Temperature and Pressure Resistance: 

In harsh operating conditions, it is crucial to select a valve that can withstand extreme temperatures and pressure levels. High-performance butterfly valves are built with robust materials such as carbon steel and stainless steel, ensuring excellent temperature resistance. With the ability to endure temperatures ranging from -320 degrees F to 1200 degrees F and pressure levels up to 1440 PSI, these valves are engineered for reliable performance in demanding environments. 

4. Fugitive Emission Control:

For applications where fugitive emissions are a concern, high-performance butterfly valves offer specialized features to ensure leak-proof operations. Stem seal extensions can be incorporated into these valves, providing enhanced emissions control and preventing fugitive leaks. This feature is particularly important in industries where environmental compliance and safety standards are paramount. 


5. Over-Travel Prevention and External Leakage Protection:

To ensure the longevity and reliability of your valve system, it's important to consider features that prevent over-travel and external leakage. Most high-performance butterfly valves include a stop in the body that prevents the disc from over-rotating, protecting the valve from potential damage. Additionally, an adjustable packing gland helps maintain a secure seal and prevents external leakage, enhancing the overall performance and efficiency of the valve. 


6. Ease of Automation:

By integrating high-performance butterfly valves with automated systems, operators can create a more controlled environment, reducing the risk of human error and potential accidents. This becomes increasingly important in demanding environments where optimal flow control is required for both operational success and personnel well-being. Selecting a high-performance butterfly valve that is designed with automation in mind can lead to enhanced productivity and cost savings. By prioritizing automation ease, you're ensuring that your high-performance butterfly valves not only excel in flow control capabilities but also seamlessly integrate into your broader automated processes, positioning your operations for increased efficiency and success. 

Conclusion 

High-performance butterfly valves offer one of the best solutions for industrial applications that require the handling of aggressive chemicals, corrosive fluids, and demanding operating conditions. To ensure you are making the right the selection of a high-performance butterfly valve, remember to consider these 6 elements: 

1. Chemical compatibility 
2. Extended size range 
3. Temperature and pressure resistance 
4. Fugitive emission control 
5. Over-travel prevention with external leakage protection 
6. Ease of automation 

When choosing a high-performance butterfly valve, rely on reputable manufacturers and make smart investments in a quality and properly selected valve to help unlock efficiency in your operations and contribute to improved reliability, reduced downtime, and enhanced safety.
