Ductile Iron Concentric Flanged Type EPDM Rubber Lined Butterfly Valve
Product introduction:
Concentric butterfly valve also named as center-lined butterfly valve, the common rubber lined butterfly valve belongs to this category. EPDM rubber lined butterfly valve is a very typical model, mainly used for opening and closing pipelines and regulating flow. Due to its simple structure, convenient operation, and good sealing performance, it is widely used in fields such as chemical, petroleum, power, and light industry. The main structure of the centerline lined butterfly valve includes the valve body, valve plate, and valve stem. Rubber lining is used between the valve plate and valve body, which can effectively prevent corrosion of the medium on the valve body.
