We offer a comprehensive range of Triple Eccentric Butterfly Valves in various pressure classes, body styles, and materials to meet critical process requirements across industries such as hydrocarbons, power generation, chemicals, fertilizers, and related sectors. The product range includes valves in ASME pressure classes up to Class 600, sizes up to 64 in. (1600 mm), and materials such as carbon steel, stainless steel, and alloy steels. These valves are suitable for operating temperatures up to 538 °C (1000 °F). Valves in higher pressure classes, larger sizes, and alternative materials are available upon customer request. The range also includes valves designed for cryogenic service. Metal-seated Triple Eccentric Butterfly Valves conform to API 609 standards. The triple-offset design provides true bi-directional operation with high-integrity, zero-leakage sealing performance. All machining operations are performed on advanced 5-axis machining centers, and customized welding machines are employed to ensure consistent quality and precision throughout the manufacturing process.
