Check valve is a mechanical device that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, having two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. They are often part of common household items. Check valves work automatically and most are not controlled by any external control. Most of the valves do not have any valve handle or stem. The external shells of check valves are made of plastic or metal. The check valve is designed for operating in a specific cracking pressure.
