Brass Check Valves
A brass check valve allows fluid to flow only in one direction. This prevents the flow of fluid in the back direction, which could cause contamination or damage to other components. Check valves work automatically and do not need to be operated. Most available types have a small spring to close the valve, the medium pressure in the forward direction opens the valve. Note that there is a minimum pressure required to open the valve (usually called cracking pressure). The housing of these valves is made out of brass, which is a cost-effective alternative to stainless steel for many applications.

Brass housing
Brass is used as the housing material. Brass is an alloy of copper and zinc and has great mechanical properties. Brass check valves are known for their durability and can be used with drinking water, gas, mineral oils, compressed air and many other non-aggressive media. But they are not suitable for use with salt water or distilled water due to the risk of dezincification. Dezincification reduces the mechanical strength of the brass by causing the zinc to be removed from the alloy resulting in a porous structure.
