Versatile Material Selection

Double Flanged Butterfly Valves are available in a range of body and disc materials such as cast iron, ductile iron, and stainless steel. Select seat and lining materials like EPDM, Nitrile, PTFE, or metal to match your applications chemical, temperature, and pressure requirements. Coating choices ensure operational longevity in both harsh and moderate environments.

Precise Standards and Pressure Ratings

Designed to comply with IS, DIN, ANSI, BS, and JIS flange standards, these valves deliver reliable performance. They undergo rigorous body test pressure at 1.5 times the rated value and seat tests at 1.1 times, ensuring safety and functionality across a broad pressure rangePN10 to PN25.

Adaptable Operation and Mounting

Choose gear, lever, or actuated operation for seamless integration into manual or automated systems. Double flanged butterfly valves can be installed in either horizontal or vertical orientations, catering to diverse piping layouts and specific service requirements.

FAQs of Double Flanged Butterfly Valves:

Q: How do you select the appropriate seat and lining material for a Double Flanged Butterfly Valve?

A: Selection depends on the applications temperature, pressure, and media. For water and common chemicals, EPDM and Nitrile are suitable, while PTFE is preferred for highly corrosive fluids. Metal seating is chosen for high-temperature or abrasive service.

Q: What are the main benefits of using a double flanged butterfly valve in industrial applications?

A: Double flanged butterfly valves provide secure double-bolted connections, ensuring minimal leakage and reliable operation under variable pressures. Their versatility in material and operation options makes them suitable for a wide array of process fluids and environments.

Q: When should I opt for a gear-operated or actuated valve instead of a lever-operated one?

A: Gear-operated or actuated valves are recommended for larger diameters (above 200mm), high-pressure systems, or when remote/automated control is needed. Lever-operated valves are suitable for smaller sizes and manual applications.

Q: Where can double flanged butterfly valves be mounted in the pipeline?

A: These valves are designed for mounting in both horizontal and vertical positions, allowing flexibility in installation as per the pipeline layout and operational needs.

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

A: Each valve undergoes rigorous body pressure testing at 1.5 times its rated value and seat testing at 1.1 times. Tests ensure leak-tightness and structural integrity, as per applicable design standards like IS 13095, EN 593, and API 609.

Q: How do these valves support diverse end connection standards?

A: Double flanged butterfly valves are manufactured to comply with multiple end connection standards (IS, DIN, ANSI, BS, JIS), ensuring easy integration with existing global pipeline systems.

Q: What range of port sizes are available, and which media can these valves handle?

A: Port sizes from 50mm to 2000mm (2 to 80) are available. The valves efficiently handle water, oil, gases, and a variety of chemicals, enabling them to serve industries from water supply to oil & gas and fire fighting.
