Large Diameter Flange Butterfly Valve

描述

This series of large-diameter flange butterfly valves originates from the mature valve manufacturing industry in Liaoyang. The product line covers an extremely wide range of specifications: the smallest size is about the thickness of a thumb, while the maximum heavy-duty valve body can weigh up to 60 tons. It can adapt to projects ranging from tiny pipelines to large pipe networks, energy, water conservancy, metallurgy and other super-large industrial projects. The product shown in the picture is a large-diameter lined flange butterfly valve. It adopts a rigid flange connection structure. The valve plate is treated with anti-corrosion lining, featuring excellent sealing performance, stable torque, low fluid resistance, flexible and reliable opening and closing. It is mainstream cut-off and regulating equipment in fluid transmission systems. Benefiting from years of technological accumulation, Liaoyang valves deliver stable quality under harsh working conditions and are exported to many countries and regions worldwide.

Core Advantages
