What is Check Valve:
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 available in a wide range of sizes and costs, check valves generally are very small,simple or inexpensive. Check 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 check valves are made of metal or palstic.
