Brass check valves, also called non-return valves, are used in many applications, often on the outlet of water pumps, or anywhere you need an inexpensive check valve to keep a flow going one way. Being a swing check design, the flapper is mostly up out of the flow, minimizing the chances of fouling from debris in the pipeline. They are standard leaded brass, 2" and smaller sizes cannot be used for potable water or consumable liquids. They have hard brass seats, no rubber seats to wear out or get damaged, but they are not considered bubble tight.
