Product Introduction
Neway Double Eccentric Butterfly Valves are designed for high-performance flow control in demanding applications, offering exceptional reliability, long service life, and tight bi-directional sealing. The double offset design features a valve stem that is offset from both the center of the disc and the centerline of the valve body. This innovative geometry allows the disc to disengage from the seat immediately upon opening, minimizing friction, reducing wear, and enhancing operational efficiency.
The precision-engineered disc profile and self-sealing seat deliver leak-tight performance with low torque operation and reduced flow resistance. Designed for easy maintenance, the resilient rubber seat is replaceable without removing the disc, reducing downtime and service costs. Ideal for potable water distribution, wastewater treatment, industrial water systems, District cooling plants and sewage networks, Neway double eccentric butterfly valves provide reliable on/off and throttling control for a wide range of fluid handling systems. Their corrosion-resistant construction also makes them suitable for aggressive and corrosive media, including seawater and chemical processing applications.
