Advanced Sealing Technology: Bubble Tight Shutoff

Featuring state-of-the-art bubble tight shutoff, this valve prevents leakage even in severe applications. Multiple seat optionsEPDM, PTFE, and metalallow you to optimize the seal for your specific media and operating conditions. This advanced sealing ensures process safety and regulatory compliance.

Flexible Installation and Universal Compliance

Designed to meet global certifications, such as API 609, BS EN 593, and more, this valve simplifies project specifications and procurement. Compatible with flanged, lug, or wafer connections, and available in extensive port sizes, it adapts effortlessly to infrastructure upgrades or new installations in any major industrial setting.

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.
