FAQ's of Offset Disc Double Flange Butterfly Valve Manufacturer:

Q: How do Offset Disc Double Flange Butterfly Valves operate?

A: Offset Disc Double Flange Butterfly Valves can be operated manually using a lever or gear, or automatically via pneumatic or electric actuators. The offset disc design reduces seat wear, ensuring a tight seal with minimal friction and making operation smoother and more reliable.

Q: What seat and disc materials are available for these valves?

A: Our valves offer a choice of seat materials like EPDM, NBR, PTFE, and metal, and disc materials including ductile iron (epoxy coated), stainless steel, and aluminum bronze. This variety helps match the valve performance to specific media, temperature, and chemical compatibility requirements.

Q: When should I choose a metal seat over a soft seat material?

A: Metal seats are ideal for high-temperature or abrasive service (up to 200C), where soft materials like EPDM or NBR may not withstand process conditions. For chemical resistance or potable water, PTFE or EPDM may be better suited. Selection depends on your application's temperature, pressure, and media.

Q: Where are these butterfly valves typically used?

A: These valves are widely used in water treatment, oil and gas facilities, chemical plants, HVAC systems, and power generation. Their robust construction and standard compliance make them suitable for both utility and critical process lines across many industries.

Q: What is the process for quality assurance and testing?

A: Each valve is tested according to international standards such as API 598 and EN 12266 to ensure leak-tight sealing and reliable performance. We maintain rigorous inspection protocols throughout manufacturing, with comprehensive testing of pressure, leakages, and functionality before delivery.

Q: What are the benefits of choosing a double flange design?

A: The double flange connection offers superior stability and leak prevention, ideal for mounting between two flanged pipe sections. This enhances safety in high-pressure services and allows easier valve installation or removal during maintenance.
