A gate valve is a pipe fitting in which the locking or regulating element moves perpendicular to the axis of the flow of the working medium. Gate valves are a very common type of shut-off valve. They are widely used on almost any technological and transport pipelines with diameters from 15 to 2000 mm in housing and communal services, gas and water supply systems, oil pipelines, energy facilities and many others at operating pressures up to 25 MPa and temperatures up to 565 °C.
