Valves come in all sizes, types, and materials. While plastic valves are currently growing in popularity, metal ones remain in prominent use for many industries. Among those readily available is the brass check valve. This metal is undeniably suitable for many plumbing applications. It is durable, strong and has a high heat resistance.


A check valve is a self-automated valve. It allows the fluid to flow in one direction before automatically preventing any from reversing (backflow) the other way. They do not require any other mechanical assistance to open and close.
