A butterfly valve is a valve where the closing member is a disc that rotates around the valve shaft to open and close, primarily serving to cut off flow in pipelines. The rubber-lined butterfly valve consists of a valve body, a butterfly disc, and a soft sealing valve seat. It is widely used for water, oil, gas, and various corrosive media at temperatures below 80℃.

Product Features
1.The valve body is symmetric relative to the centerline, making installation easy and time-saving.
2.The valve seat is available in various materials such as PTFE, nitrile rubber, etc., which are non-detachable, stretch-resistant, leak-proof, and easy to replace.
3.The integral valve stem structure ensures high stem strength, fine processing, and resistance to deformation, thus preventing external leakage.
4.The butterfly disc has high precision, is polished, and provides a high degree of cooperation with the valve seat, ensuring excellent sealing performance.
