Product Overview
The Double Eccentric High Performance Flanged Butterfly Valve is engineered for reliable shut-off and long service life in medium- to high-pressure industrial piping systems.
The double offset disc design significantly reduces friction between the disc and seat during operation, minimizing wear and ensuring consistent sealing performance.
With a flanged body connection, the valve provides enhanced structural strength and stable installation, making it suitable for oil & gas, chemical processing, power generation, HVAC, and industrial water systems.
