Product Overview
The lift-type check valve, also known as a check valve or one-way valve, is a valve where the disc moves along the vertical centerline of the valve body. It operates by utilizing the natural flow of the medium within the pipeline to maintain the valve in either an open or closed position, effectively preventing backflow. This product is widely used in industries such as petroleum, chemical, and textile dyeing, and can be applied to media including water, steam, and oils.
