Draft Beer CO2 Gas Shut Off Switch with Check Valve For CO2 Regulators
Attach to your regulator, has a check valve.. Helps you to easily turn off gas when needed. For CO2 beer keg gas regulators. All brass with on/off lever and check valve. A gas check valve allows gas to flow only in one direction. Most homebrew keg couplers do not have a built in gas check valve. So, for home brewing beer systems it is very important to have a regulator shutoff with a check valve, like this one. Without a check valve, any loss of gas pressure will cause beer to back up into the gas line and into your regulator. So when buying a gas regulator for your home brew coupler, your should also buy this shutoff with a check valve so the standard shutoff on your regulator can be replaced.
