Product Description
A Unidirectional Seal Knife Gate Valve is a type of valve commonly used in industrial applications where there is a need to control the flow of slurries, thick liquids, and other challenging fluids. The valve is designed to handle tough materials that may include particles, fibers, or sludges that could clog traditional valves. The unidirectional seal feature means that the valve is specifically designed to operate effectively in only one direction of flow, providing a tight seal under that specific operating condition.
