What is a Secondary Regulator?

A regulator is an integral part of the kegging system and it is used to control the flow of Carbon dioxide or Nitrogen from the gas tank to the keg at a safe pressure. There are different types of regulators used in the kegging system and it is important to know about the different types of regulators, especially if you are planning to improve your knowledge in kegging.

In an ordinary kegging setup with only one keg, a primary regulator is all that is needed. However, if you have been brewing and kegging your own beer for a while, then you must have wanted to experiment with dispensing using more than one keg. If you are using two or more kegs, then you need another regulator. This is where the secondary regulator comes in. (more info below)

The secondary regulator allows you to regulate the pressure of each individual keg that you have. It is a great addition that you can include in your kegging system to make it work more efficiently. If you are storing and pouring beer from several kegs, you may need to have a different output pressure for each of the kegs that you are using.

Unlike the primary regulator, the secondary regulator is not connected to the gas tank directly. There are several things that you need to attach to the primary regulator before the secondary regulator is installed. To install the secondary regulator, they need hose nipples and adjustment screws so that you can dispense in multiple kegs using a single gas source. They also require shut-off and safety relief valves.

While the function of the secondary regulator is very different from the primary regulator, they have some similarities. For instance, most have the same output pressure gauge of up to 60 PSI. This is to ensure that all kegs can dispense using the same pressure.
