We offer a comprehensive range of triple eccentric butterfly valves in various pressure classes, body styles, and materials to meet critical process requirements across diverse industries, including hydrocarbon, power, chemical, and fertilizer sectors. The product range includes valves up to ASME class 600, in sizes up to 64" (1600 mm), and in carbon steel, stainless steel, and alloy steels, suitable for temperatures as high as 538°C (1000°F). Valves in higher pressure classes, larger sizes, or alternative materials are also available based on customer requirements, including options for cryogenic services. The metal-seated valves conform to API 609 standards. Triple offset butterfly valves are fully bi-directional and provide high-integrity sealing. All machining operations are performed on advanced 5-axis machining centers, and customized welding machines are employed to ensure precision and quality in the manufacture of these valves.
