FAQs of Butterfly Valve:

Q: How is the butterfly valve operated and what control options are available?

A: The butterfly valve operates using a quarter-turn mechanism, which can be controlled either manually by a lever or with a manual gear system, according to application needs.

Q: What are the main benefits of the epoxy powder coated body on this valve?

A: The epoxy powder coating provides a protective layer that enhances corrosion resistance and durability, making the valve especially suitable for harsh or demanding industrial environments.

Q: Where can this butterfly valve be installed, and what types of fluids is it suitable for?

A: It is designed for use in HVAC, fire protection, water treatment, irrigation, and food processing systems. The valve can handle water, oil, gas, and other non-corrosive fluids effectively.

Q: What seat materials are available, and how do I choose the right one for my application?

A: Seat options include EPDM, NBR, PTFE, and Viton. EPDM and NBR are common for water and general services, PTFE is chemical-resistant, and Viton is well-suited for higher temperatures and aggressive media. Select the seat material based on the fluid type, temperature, and chemical compatibility.

Q: How does the valve ensure leak-tight performance under pressure?

A: The valve is designed for bi-directional tight shut off, with shell and seat testing conducted at 1.5x and 1.1x design pressure respectively, ensuring reliable performance and minimizing the risk of leakage.

Q: What makes this butterfly valve suitable for long-term use?

A: With a working life exceeding 50,000 cycles, robust pin construction in stainless steel, and superior sealing materials, this valve is built to deliver sustained, maintenance-friendly operation in industrial settings.

Q: What sizes and end connections are available for this butterfly valve?

A: The valve comes in sizes from DN50 to DN300 (2 to 12 inches), and is available with wafer, flanged, or lug-type end connections to fit a wide range of piping systems.
