This Regulator is perfect for those who want to keep different pressure on different beer styles. It is also used for those who wish to have beer and soda off the same CO2 tank. You can serve multiple kegs with this system by adding an air distributor to one or both outlets. The gauge has two shut off valves with check valves on each. This keeps beer from flowing back into your system. This three gauge system allows you to monitor your tank pressure and two different output pressures at the same time. We build and test these high quality regulators in house using an American made body and other high quality componants.
