Butterfly valve knowledge

Butterfly valve is a kind of valve that opens and closes by rotating the disc around the valve shaft to control the flow of fluid in the pipeline.

Air, water, steam, various corrosive media, mud, oil, liquid metals, radioactive media and other types of fluid flow can be controlled through the butterfly valve, mainly cutting off and throttling pipelines. Disc-shaped butterfly plate as the opening and closing parts, in the valve body around its own axis rotation, to achieve the purpose of opening and closing or regulation.

The butterfly valve manufacturer stated that the butterfly valve is suitable for flow regulation. Due to the significant pressure loss in the pipeline, approximately three times that of the gate valve, the impact of pressure loss on the pipeline system should be fully considered during selection, as well as the strength of the butterfly valve under the pressure of the pipeline medium. Additionally, the working temperature limit of the elastic valve seat material at high temperatures should also be taken into account.

The structure length and overall height of the butterfly valve are smaller, with a faster opening and closing speed, and good fluid control characteristics. This structural principle is suitable for manufacturing large diameter valves. When flow control is required, it is important to select the correct specification and type for proper and effective operation.
