Check valve is also known as reverse flow valve, check valve, back pressure valve and one-way valve. These valves are automatically opened and closed by the flow of the medium itself in the pipeline, belonging to an automatic valve. Used in pipeline system, its main function is to prevent medium backflow, prevent pump and drive motor reverse, as well as the discharge of container medium. It can also be used to supply lines for auxiliary systems in which pressure may rise to exceed system pressure. It can be divided into swing type (rotating according to the center of gravity) and lift type (moving along the axis).
Flanged check valves can also be used to supply lines in which pressure may rise to an auxiliary system that exceeds the system pressure. It can be divided into swing type and lift type. Swing type is suitable for petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industries and other working conditions of pipeline with pressure PN1.6~ 16.0mpa and working temperature -29~+550°.
