ABO's 3E Series triple eccentricity butterfly valves are designed for operation in very demanding environments that require high safety, trouble-free operation and minimal maintenance. The triple eccentricity design contributes to a very efficient metal-to-metal sealing principle, which is designed primarily for high parameter sealing at both pressures and temperatures. The appropriately designed geometry eliminates friction between the seating surfaces of the sealing TRIM, which aids in the longevity of the damper. The main sealing node is formed by a high precision sealing pair with a special bevelled cone geometry.NOMINAL SIZE:
