What is a check valve?
Check valves are used to ensure that gases and liquids flow in only one direction. They essentially prevent the process flow from flowing back, thus forcing the valve to close. Correct flow pressure forces the check valve open, while reverse flow causes the valve to close.     
 
Flow check valves                open at the designed minimum flow or cracking pressure so that the valve can begin operation. Check valves protect the system from pressure fluctuations that can cause damage to pumps and pipes and help operate efficiently. Check valves are required to stop backflow and protect rotating equipment and machinery from sudden backflow surges that may occur.
