Gate valves are designed for installation on pipelines as shut-off devices and for regulating the flow of working media in water supply systems (except for drinking water systems) and in the chemical industry. The principle of operation of gate valves is based on the movement of the gate (blade) perpendicular to the flow of the medium. When the nominal diameter of the pipeline is completely blocked, the flow stops; when partially blocked, the flow is regulated.
