Two regulator bodies give more flexibility in beer dispensing. Each regulator body has a low pressure gauge, and there is one high pressure gauge to read the tank pressure. A double body regulator makes it possible to serve beers under different pressures for different beer styles. It is also possible to adjust pressures when one keg is full and one near empty. That means more control to prevent flat beer or foaming. Another common use for double body regulator is to carbonate under higher pressure, while maintaining lower pressure for serving.
This regulator has 5/16" Barb Check valves.
