Flanged Check Valve PN16 for Fire Protection & Water Supply Systems

DN50–DN600 PN10/PN16 Swing Check Valve for Water & Municipal Projects

• A check valve, non-return valve, reflux valve, retention valve, foot 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. Check valves generally are very small, simple, and 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 plastic or metal.
