Product Introduction
Neway double eccentric butterfly valve has an excellent structure and high reliability. The structural feature is that the axis of the valve stem deviates both from the center of the butterfly disc and from the center of the body. Neway double eccentric design enables the butterfly disc to quickly separate from the seat after the valve is opened, significantly reducing the unnecessary excessive compression between the butterfly disc and seat. It achieves two-way tight closure and has a self-sealing design with reliable sealing performance. The special valve disc design results in lower flow resistance. The rubber seat can be replaced without disassembling the disc. It can be widely applied to water supply systems, drainage and water supply systems, sewage treatment systems, etc., and is used for cutting off and regulating flow.
