2025-11-19
The Double Eccentric Butterfly Valve is a high - performance valve. Its double - eccentric design reduces friction between the disc and seat during opening and closing, enhancing sealing and extending service life. It's suitable for various industries like water treatment and HVAC systems, offering reliable flow control and high - efficiency operation.
The Double Eccentric Butterfly Valve is an advanced flow control solution engineered for superior performance and longevity in demanding applications. Its design incorporates two distinct offsets: the first offset positions the stem axis behind the disc seat plane, and the second offset places it slightly off the disc centerline. This double eccentricity is a fundamental feature that ensures the disc completely disengages from the seat seal during the initial 10 degrees of opening, virtually eliminating wear and friction. This mechanical action guarantees a tight, bubble-seal shut-off when closed and minimizes operating torque, enhancing the valve's operational efficiency and service life.
Constructed with robust materials like a stainless steel stem and a resilient seated design, the Double Eccentric Butterfly Valve exhibits exceptional corrosion resistance and durability. It is ideally suited for a wide spectrum of services, including water supply, wastewater treatment, HVAC systems, marine applications, and various industrial processes involving oils, gases, and mild chemicals. The reliable sealing performance and low-maintenance requirements of the Double Eccentric Butterfly Valve make it an indispensable component for critical isolation and regulation duties in pipelines.
