Product Introduction
Knife gate valve is a on-off valve with simple and sturdy structure, which can be used for the switch control of media containing solid particles or impurities in pipelines.
Rising stem knife gate valve refers to a valve where the stem is exposed outside the body. When the valve is opened or closed, the valve stem and gate move up and down synchronously, and the opening status can be directly observed through the position of the stem.
Knife gate valve can be used to control the flow of various media such as slurry, sewage, coal slurry, ore pulp, and high-viscosity liquids. It mainly plays the role of cutting off in the pipeline. It is widely used in many fields such as water treatment, mining, paper making, and chemical industry, etc.
