Butterfly Valve Butterfly valve, also called flip valve, is a regulating valve with a simple structure and can also be used for switching control of low-pressure pipeline media. Butterfly valve means that the closing part (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve A valve that opens and closes. The valve can be used to control the flow of various types of fluids such as air, water vapor, various corrosive media, mud, oil, liquid metal, and radioactive media. It mainly plays the role of cutting and throttling on pipelines. The butterfly valve opening and closing part is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. Butterfly valve (English) refers to a valve whose closing member (valve disc or butterfly plate) is a disc that rotates around the valve axis to open and close. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The range from fully open to fully closed of the butterfly valve is usually smaller than that of the butterfly valve and the butterfly rod itself does not have self-locking ability. In order to position the butterfly plate, a worm gear reducer must be installed on the valve rod. The use of worm gear reducer not only makes the butterfly plate self-locking, allowing the butterfly plate to stop at any position, but also improves the operating performance of the valve. The characteristics of the industrial butterfly valve are that it can withstand high temperatures and has a high applicable pressure range. The valve has a large nominal diameter and the valve body is made of carbon steel. The sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used in flue ducts and gas pipelines for high-temperature media.
