Double Flanged Eccentric Butterfly Valve Series 14 Big size QT450 GGG40 with stainsteel ring
Double flange eccentric butterfly valve is a key component in industrial piping systems. It is designed to regulate or stop the flow of various fluids in pipelines, including natural gas, oil and water. This valve is widely used because of its reliable performance, durability and high cost performance.
Double flange eccentric butterfly valve is named because of its unique design. It consists of a disc-shaped valve body with a metal or elastomer seal that pivots about a central axis. The valve disc is sealed on a flexible soft seat or metal seat ring to control flow. The eccentric design ensures that the disc always contacts the seal at only one point, reducing wear and extending the life of the valve.
One of the main advantages of the double flange eccentric butterfly valve is its excellent sealing capability. Elastomeric seals provide a tight closure ensuring zero leakage even under high pressure. It also has excellent resistance to chemicals and other corrosive substances, making it suitable for use in harsh environments.
Another noteworthy feature of this valve is its low torque operation. The disc is offset from the center of the valve, allowing for a quick and easy opening and closing mechanism. The reduced torque requirements make it suitable for use in automated systems, saving energy and ensuring efficient operation.
In addition to their functionality, double flange eccentric butterfly valves are also known for their ease of installation and maintenance. With its dual-flange design, it easily bolts into pipes without the need for additional flanges or fittings. Its simple design also ensures easy maintenance and repairs.
When selecting a double flange eccentric butterfly valve, factors such as operating pressure, temperature, fluid compatibility and system requirements must be considered. In addition, checking relevant industry standards and certifications is crucial to ensure that the valve meets the necessary quality and safety standards.
To sum up, the double-flange eccentric butterfly valve is a multi-purpose and practical valve used in various industries to control fluid flow. Its unique design, reliable sealing capabilities, low-torque operation, and ease of installation and maintenance make it ideal for many piping systems. By understanding its characteristics and considering the specific requirements of the application, one can select the most appropriate valve for optimal performance and long-lasting functionality.
