Product Introduction

Butterfly valve is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. Butterfly valve refers to a valve in which the closing part is a disc, which rotates around the valve shaft 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, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. It is widely used in many fields such as water treatment, petroleum, chemical industry, metallurgy, hydropower, etc.
