A double check valve accepts air from two sources and delivers it to a common outlet.
This kind of valve is used when an element must receive air from the higher of two sources of pressure.
An internal disc moves in response to the higher air pressure and allows it to flow out of the delivery port. It is recommended to mount these valves in a way the disc operates horizontally.
