APCO AIR RELEASE VALVES

Viking Alarm Check Valve

check valve


A valve that closes to prevent backward flow of liquid


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


Limits the flow of gas to one direction only. Use a check valve between the bubbler and generator to prevent unwanted pressure build up in the generator, and a safety against a low level bubbler. A check valve, such as used on torches, is recommended.


A valve which will allow water to pass in one direction but will close and prevent flow (backflow) in the opposite direction.
