Metal Seal butterfly valve : Valve Size Range: Specifies the range of valve sizes available, typically ranging from a few inches to several feet in diameter, to accommodate different flow rates and piping system requirements. Pressure Rating: Indicates the maximum pressure at which the valve can safely operate. Pressure ratings can vary widely depending on the valve size, design, and materials, ranging from ANSI Class 150 to Class 2500 or higher. Temperature Rating: Specifies the maximum and minimum temperatures at which the valve can operate effectively and safely. Metal seal butterfly valves are often designed to withstand elevated temperatures, ranging from -20°C to 500°C or higher, depending on the materials used and the specific design. Body Material: The body of the valve is typically made from stainless steel or other high-strength alloys for corrosion resistance and durability. Seal Material: Metal-to-metal seals are used for tight shut-off and reliable performance. Sealing materials may include stainless steel, stellite, tungsten carbide, or other hard alloys. Seat Material: The valve seat may be made from the same materials as the seal or from materials such as PTFE for additional sealing properties. End Connections: Specifies the type of end connections available for the valve, such as wafer, lug, or double-flanged connections, to facilitate installation and connection to the piping system. Design Standards: Indicates the industry standards and specifications with which the valve complies, such as API 609, ASME B16.34, ISO 5752, or other applicable standards, to ensure quality, performance, and safety. Metal seal butterfly valves offer several advantages over other types of butterfly valves, particularly those with elastomeric seals: High Temperature Resistance: Metal seals can withstand higher temperatures compared to elastomeric seals. This makes metal seal butterfly valves suitable for applications involving high-temperature fluids or environments. Chemical Compatibility: Metal seals are more chemically resistant than elastomeric seals. They can handle a broader range of fluids, including corrosive and abrasive media, without degradation or deterioration. Longer Service Life: Due to their robust construction and resistance to wear and tear, metal seal butterfly valves tend to have a longer service life compared to valves with elastomeric seals. This can result in lower maintenance costs and reduced downtime for replacement or repair. Tight Shutoff: Metal seals provide a tighter shutoff compared to elastomeric seals, especially in high-pressure applications. This ensures better control over flow rates and minimizes leakage, enhancing overall system efficiency. The metal seal butterfly valve regulates flow by rotating the disc within the flow path. When the valve is fully open, the disc is positioned parallel to the flow direction, allowing fluid to pass through with minimal obstruction. Conversely, when the valve is closed, the disc is rotated perpendicular to the flow, blocking the passage of fluid. Butterfly valves are commonly applicating in a variety of industries, including: Oil and Gas: Triple offset butterfly valves applicate in the oil and gas industry. For pipeline isolation, compressor stations, and refining processes. Chemical: Triple offset butterfly valves are popular in chemical plants for applications. Such as corrosive and abrasive fluid handling, high-temperature services, and toxic gas handling. Power Generation: Triple offset butterfly valves play an important role in power generation.
