A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.

Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, these valves generally are very small, simple, or inexpensive. These valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most valves are made of plastic or metal.
