Description
Technical Field

Background
The butterfly valve is a regulating valve with simple structure. Butterfly valves, also known as flap valves, are used for the on-off control of low pressure pipeline media, and refer to valves in which the closure member (flap or butterfly plate) is a disk that rotates about the valve axis to achieve opening and closing. The butterfly valve is a valve which is turned back and forth by about 90 degrees by a disc type opening and closing member to open, close or regulate the flow of medium. The butterfly valve has the advantages of simple structure, small volume, light weight, material consumption saving, small installation size, small driving moment, simple and rapid operation, and good flow regulation function and closing sealing property.
