FAQs of PFA Lined Lug Type Butterfly Valve:

Q: How does the PFA lining benefit the butterfly valves operation in chemical processing?

A: PFA (Perfluoroalkoxy) lining offers exceptional corrosion resistance, protecting both the valve body and internal components when handling aggressive chemicals. This ensures reliable sealing, enhances durability, and extends the service life of the valve in demanding chemical industries.

Q: What is the process for installing a PFA Lined Lug Type Butterfly Valve?

A: Installation involves aligning the lug-type valve between pipeline flanges as per ANSI/ASME B16.5, tightening the bolts without overtightening, and ensuring the gasket surfaces are intact. The valve can be mounted horizontally or vertically, depending on piping requirements.

Q: When should I use an electric or pneumatic actuator instead of manual operation?

A: Electric or pneumatic actuators are recommended when remote or automated control is needed, frequent cycling occurs, or for valves in hard-to-reach or hazardous locations. Manual levers or gears are suitable for infrequent operation or where quick service is needed.

Q: Where can this butterfly valve be applied within industrial sectors?

A: The valve is highly suitable for chemical processing, petrochemical, pharmaceutical, and wastewater treatment applications due to its corrosion resistance, bubble-tight sealing, and compliance with international standards.

Q: What are the benefits of choosing a lug type connection for butterfly valves?

A: Lug type connections provide secure mounting, easy installation and removal from the line, and facilitate dead-end service. They also comply with ANSI/ASME B16.5 flange patterns for compatibility and improved maintenance access.

Q: How easy is it to maintain and service the PFA Lined Lug Type Butterfly Valve?

A: Minimal maintenance is required due to the PFA linings resistance to chemical attack and build-up. Regular inspection for wear on seals and moving parts is recommended. The simple design allows for easy disassembly and maintenance when needed.

Q: What is the valves maximum operating pressure and temperature range?

A: The PFA Lined Lug Type Butterfly Valve is rated for pressures up to 10 Bar (PN 10/16) and can handle temperatures from -20C to +180C, making it suitable for a wide array of industrial media and process conditions.
