The check valve depends on the medium's flowing. It opens automatically and closes the valve flap to prevent media from flowing backwards. It is also called as shut-off valve, one-way valve, reflux valve and back pressure valve. The check valve is a kind of an automatic valve. It is mainly used to prevent media from flowing backwards, the pump and drive motor from inversion, and bleeding from the container. The check valve can also be used for the pipe to help the auxiliary system where the pressure exceeds the system pressure.
