A check valve also is called a non-return valve, reflux valve, retention valve, foot valve, or one-way valve that is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Where are check valves used?
Check valves are used in many different applications. For example, they are often placed on the outlet side of a pump, to protect the pump from backflow. Centrifugal pumps, the most common type of water pumps, are not self-priming, and therefore check valves are essential for keeping water in the pipes. Also, check valves are very often used in HVAC systems (Heating, Ventilating and Air Conditioning-systems). HVAC systems are e.g. used in large buildings, where a coolant is pumped many stories up. The check valves are here installed to make sure that the coolant is not flushing back down.
