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