Basic Introduction To Butterfly Valves

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

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. It mainly serves as a cutting and throttling function on pipelines. The butterfly valve opening and closing component is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve the purpose of opening and closing or adjusting.
