Product Introduction
Neway concentric butterfly valve comes in various forms such as flange type, lug type and wafer type. The sealing effect is mainly achieved through the interference fit between the rubber valve seat and the valve disc. The design of the Neway concentric butterfly valve is relatively simple, with low operating torque, low flow resistance, good corrosion resistance of the valve body lining, and high reliability. It is widely applicable for use in water supply systems, industrial water systems, sewage treatment systems, and other industries for cutting off and regulating water flow. At the same time, it is also suitable for use in systems with strong corrosiveness (such as seawater treatment, etc.) for cutting off and regulating water flow.
