Cast Steel and Cast Iron/Ductile Iron Butterfly Valves

Butterfly valves are essential components in various industrial applications, particularly in water and general industrial systems. These valves come in different types, including wafer, lugged, and double flanged styles, with options for metal or soft seats. They are designed for low-pressure operations (Pn < 1.6 MPa) and can be operated manually using levers or gears. The valves feature a double eccentric sealing structure, ensuring efficient performance and durability. Made from materials such as cast iron, ductile iron, carbon steel, and stainless steel, these butterfly valves are suitable for medium temperature ranges (120°C < T < 450°C). They are manufactured according to international standards like API 609 and tested under API 598 protocols. Their dimensions follow ANSI B16.1, B16.5, B16.47, DIN, BS, and JIS specifications, ensuring compatibility across global systems. The valves are available in sizes ranging from 2" to 60", making them versatile for a wide range of piping systems. They are commonly used in water treatment, chemical processing, and other industrial sectors where reliable flow control is critical. The design includes features like resilient seats, lubricated bronze bushings, and PTFE seals, which enhance their sealing performance and longevity. Valve bodies are typically cast, providing structural strength and resistance to corrosion. The disc types include centerline and eccentric designs, offering flexibility depending on the application requirements. Additional options include electric or pneumatic actuators for automated operation. Key specifications include compliance with API 609, ANSI B16.10, and ANSI B16.5 standards. Materials used vary from WCB, WCC, WC6, WC9, CF8, CF8M, and more, allowing customization based on specific environmental and operational needs. The valves are packaged in wooden cases for safe transportation. Dimensions and weights are provided for sizes ranging from 2" (DN50) up to 32" (DN800), with detailed measurements for A, B, C, L, E, F, and weight in kilograms. This comprehensive data helps in selecting the right valve size for specific projects. Overall, these butterfly valves offer high performance, reliability, and adaptability, making them a preferred choice in numerous industrial settings. Whether for water systems, chemical plants, or power generation, they provide an effective solution for controlling fluid flow with precision and efficiency.
