CO2 gas pressure regulator for dispensing
We have several types of pressure regulators, such as nitrogen regulators or CO2 regulators, which are the main ones. You may also hear about water pressure regulators or water reducers and, although they are different products, they all serve the same purpose: reducing pressure.
CO2 regulators are an essential accessory for serving beer, and their function is to control the flow of CO2 injected into the beer keg. It is worth stressing that when we talk about injecting CO2 into the keg, we are always referring to dispensing, since CO2 is also used in brewing itself, which we will not go into here. That said, what is the CO2 we inject into the keg for? It has two very clear purposes. The first is to push the beer out of the keg: beer needs another element to force it out of the keg.
The second purpose of injecting CO2 into the keg is to occupy the space created inside the keg as the beer is dispensed. But why do you need a CO2 regulator? Beer contains its own CO2 or gas, which looks for a way out, and to prevent the beer from going flat you need to inject external gas to regulate the pressure coming from the CO2 cylinder and balance the CO2 that is trying to escape from the beer with the CO2 you inject. This is called equilibrium pressure, and it is so delicate that if you set the pressure too high you can over‑carbonate the beer, and if you set it too low you will allow the beer to release its CO2 and go flat.
At installbeer.com you can find all kinds of regulators, from special regulators for 600 g and 1300 g cylinders to regulators that can control 1, 2, 3 or 4 pressures on a single unit; you can even regulate more pressures using a low‑pressure regulator.
We have two‑body and three‑body regulators, low‑pressure regulators and special models for 600 g and 1300 g cylinders.
Pressure issues are a classic in our sector, and achieving equilibrium pressure is not always easy, as there are many factors to consider, such as the temperature of the beer in the keg or the beer’s own carbonation level. At Install Beer we have been installing, repairing and maintaining dispensing equipment for over 20 years, including accessories such as regulators, which are very delicate components and are responsible for ensuring that your beer pours perfectly.
If you have problems with foam, gas leaks or any other technical issue, do not hesitate to contact us at infonstallbeer.com. We offer personalised support and will find the best solution to your problem.
The regulator is a delicate component because it is subjected to high pressures, and a malfunctioning regulator can cause your beer to pour poorly and all the CO2 in the cylinder to be lost. There are certain regulator accessories you should consider if you are experiencing gas losses or foam problems, and at Install Beer we stock many of the spare parts you may need, such as metalbuna seals, high‑ and low‑pressure balls, protectors and many more.
Regulator or gauge hose that controls the pressure from the gas cylinder (high‑pressure source) and connects it to the beer keg via the keg valve (reducing the pressure). When a pressure is recommended, it is usually specified.

Sealant for regulator: Sealant and threadlocker for all types of threaded connections. Provides high anaerobic resistance to pressure. NR08CLP‑NY007 approved.
Metal and rubber seal for the connection between the regulator and the gas cylinder. Necessary to prevent leaks or micro‑leaks at the connection.
The pressure regulator is a component that connects to the CO2 cylinder to regulate the pressure entering the beer keg. It is a basic element in a beer installation to ensure everything works perfectly and the beer pours correctly.
The pressure regulator is connected to the CO2 cylinder. Once connected, we can adjust the pressure to set the equilibrium pressure. The gauges at the top are the low‑pressure gauges and show the pressure being introduced into the keg. The gauge at the bottom left is the high‑pressure gauge and shows what the cylinder is delivering.
To know how many bodies (outlets) you need on the pressure regulator, it will depend on how many different pressures you want to be able to set. For example, if you have two kegs that require different pressures, you will need a two‑body regulator. But if you have two kegs running at the same pressure, you can buy a single‑body regulator and add a splitter for two lines so they both feed the two kegs.
