FAQs of Double Offset Butterfly Valve:
Q: How does a double offset butterfly valve ensure bubble-tight shut off?
A: The double offset design positions the disc away from the seal, minimizing wear and enabling precise, repeated contact for a bubble-tight shut off. This feature, combined with high-quality seat materials like EPDM, PTFE, or metal, reliably prevents leakage even in high-pressure and high-temperature environments.
Q: What are the advantages of stainless steel discs and shafts in this valve?
A: Stainless steel discs (CF8/CF8M) and shafts (AISI 410/316) provide superior corrosion resistance, mechanical strength, and durability. This construction is ideal for processes involving corrosive fluids or aggressive operating conditions, enhancing valve lifespan and reducing maintenance frequency.
Q: Where can double offset butterfly valves be used?
A: These valves are widely used in HVAC, waterworks, power plants, oil & gas, and chemical industries. Their high corrosion resistance, flexibility of connection types, and compatibility with various media (water, oil, gas, chemicals) make them particularly advantageous for both critical and standard applications.
Q: When should you choose EPDM, PTFE, or metal seated valves?
A: EPDM seats are best for water and non-corrosive applications, PTFE suits aggressive chemicals or higher temperatures, and metal seats provide robust sealing for abrasive or high-temperature services. Selection depends on your specific process media and operating conditions.
Q: How can the valve be operated and automated?
A: This valve is designed for versatile operation. Manual lever and gear options suit simple installations, while pneumatic or electric actuators enable automation, remote control, and integration into complex process systems.
Q: What international standards does the valve comply with?
A: It complies with API 609 and BS EN 593 design standards, API 598 and ISO 5208 test standards, and face-to-face requirements from EN 558 Series 20/API 609. Connection compatibility includes EN 1092-2 and ASME B16.5 flanges, ensuring global suitability and straightforward project approval.
Q: What is the process for installation and maintenance?
A: Installation is flexible due to the flanged, lug, or wafer end connections and a round shape that fits standard pipelines. Routine maintenance mostly involves checking seat integrity and actuator function, simplified by the valves accessible design and corrosion-resistant materials.
