Check Valve refers to a valve that automatically opens and closes the valve disc based on the medium's own movement to prevent the medium from flowing back. It is also called a check valve, a one-way valve, a reverse flow valve and a back pressure valve. It belongs to an active valve. For example, on a ship, in order to prevent seawater from flowing back, a check valve must be used in the sea pipe system. It is primarily for safety considerations.
