1purpose

Widely used in pipelines of petroleum, chemical, food, medicine, papermaking, hydropower, ships, water supply and drainage, metallurgy, energy and other systems, suitable for various corrosive gases, liquids, semi liquids and solid powder media.

IIOverview

Also known as a flap valve, it is a type of regulating valve with a simple structure. Butterfly valve refers to a valve whose closing element (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing. It is mainly used for cutting off and throttling in pipelines.

IIIClassification of

Butterfly valves can be divided into soft sealed butterfly valves and hard sealed butterfly valves according to their sealing surfaces; According to the connection method, it can be divided into clamp butterfly valves, flange butterfly valves, and welded butterfly valves; According to the driving mode, it can be divided into manual butterfly valves, turbine butterfly valves, pneumatic butterfly valves, electric butterfly valves, etc.
