Key Features and Advantages
Triple Eccentric Design for Best Performance
One of the great majority notable features of the Triple Eccentric Butterfly Valve is its unique triple offset structure. This design ensures that the sealing surfaces only come into contact during full closure, reducing operational torque and wear. As a result, the valve provides smooth operation, increased durability, and a highly effective sealing performance.
Special Corrosion and Temperature ResistanceBuilt to withstand the limit environments, the Triple Eccentric Butterfly Valve is manufactured using high-performance materials such as high-temperature steel, stainless steel, and duplex steel. The valve seat is reinforced with stellite, a durable alloy known for its resistance to corrosion, oxidation, and high temperatures up to 800°C. These properties make it highly suitable for aggressive media, including chemicals and steam.
Reliable Zero Leakage PerformanceThe Triple Eccentric Butterfly Valve incorporates a metal-to-metal sealing mechanism, ensuring tight shutoff performance and zero leakage. This feature is particularly critical in applications where leak prevention is essential, such as chemical processing and high-pressure fluid control. The combination of a precision-engineered sealing surface and advanced materials enhances the reliability of the valve under varying pressure conditions.
Structural Strength and DurabilityHigh-Quality Materials for Longevity
The Triple Eccentric Butterfly Valve is designed with a robust structure, utilizing high quality materials such as XM-19, duplex steel, and Inconel X-750 for the stem. These materials provide good mechanical strength and resistance to wear, ensuring prolonged service life even under harsh operating conditions. Additionally, the flexible graphite packing enhances the valve’s ability to maintain a secure seal while preventing leakage.
Enhanced Safety with Anti-Blowout ShaftTo ensure to a certain extent safety during operation, the Triple Eccentric Butterfly Valve is equipped with an anti-blowout shaft design. This feature prevents the valve stem from being ejected under high pressure, enhancing the overall operational security of the system.
Versatile and Customizable SolutionsWide Range of Sizes and Pressure Ratings
The Triple Eccentric Butterfly Valve is available in a broad range of sizes, from 2” to 72”, and supports pressure ratings from Class 150 to 900LB (PN6 to PN100). This versatility makes it adaptable for various industrial applications, from low-pressure water control systems to high-pressure steam and gas distribution networks.
Multiple Connection and Operation OptionsDesigned for compatibility with different pipeline configurations, the Triple Eccentric Butterfly Valve is available with flange, wafer, and lug end connections. It also offers multiple operation methods, including manual lever, worm gear, electric, and pneumatic actuation, providing flexibility based on system requirements.
Compliance with Industry StandardsThe Triple Eccentric Butterfly Valve is engineered and manufactured in accordance with globally recognized standards such as API 609, ASME B16.10, and ISO 5752. Inspection and testing are conducted per API 598 and EN12266 to ensure quality and reliability. These certifications guarantee that the valve meets limit industry standards for performance and safety.
The Triple Eccentric Butterfly Valve is an good choice for industries requiring high-performance flow control solutions. With its triple eccentric design, good materials, zero leakage capability, and compliance with international standards, this valve provides long-lasting durability and reliable operation in to the limit conditions. -
