Ductile Iron GG25 GGG40 GGG50 Lug Butterfly Valves For PN10 PN16 PN25

Series No. BFV-1005

A butterfly valve, also known as a flap valve, is a simple structure regulating valve that can be used for switch control of low-pressure pipeline media. The butterfly valve refers to a valve with a disc as the closing component (valve disc or butterfly plate) that rotates around the valve axis to achieve opening and closing.

Butterfly Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. Mainly used for cutting and throttling on pipelines. The butterfly valve opening and closing part is a disc shaped butterfly plate that rotates around its own axis within the valve body to achieve the purpose of opening, closing or adjusting.
