It is a valve that is uniquely engineered to help you control or regulate the amount of food-grade nitrous oxide you inject into a whipped cream dispenser. It helps control the flow of nitrous oxide from a high-pressure point (the N2O tank) to a low-pressure point (the dispenser). A nitrous oxide pressure regulator is made up of the following parts.

  • Inlet Port

This port connects to the nozzle adaptor on a 615g or 640g nitrous oxide tank. It connects the high-pressure source tank to the pressure regulator (valve).

  • Outlet Port

This port delivers regulated nitrous oxide gas from the pressure regulator to the low-pressure system or the whipped cream dispenser. A pressure regulator hose and a quick connect system are used to attach this port to a whipped cream dispenser.

  • The Valve

It is an innovative mechanism that senses the pressure of the nitrous oxide gas from the N2O tank. Then it controls or regulates the flow of nitrous oxide through the pressure regulator.

  • Pressure Gauges

A nitrous oxide pressure regulator has two gauges. The one on the left displays the working pressure and the one on the right displays the gas cylinder pressure.

  • Control Knob

This is the plastic or metallic knob at the top of the valve. This knob helps you manually adjust the regulated pressure that goes into the whipped cream dispenser.

Why Do We Need a Pressure Regulator with Whipped Cream Chargers?

We need a pressure regulator when using a whipped cream nitrous oxide tank to control and regulate the pressure of nitrous oxide going into the whipped cream dispenser.

As we mentioned earlier, this device has two pressure gauges. The working pressure gauge (on the left) and the gas cylinder pressure gauge (on the right). This makes it easy to monitor both the working and gas cylinder pressure at the same time. You can capably adjust the amount of culinary-grade nitrous oxide gas that goes into the dispenser by monitoring the pressure gauges.

Most nitrous oxide pressure regulators on the market meet strict quality control standards. This means they have been tested for safety and efficiency. A pressure regulator helps keep you safe by reducing the pressure of nitrous oxide gas to a usable level. You will not experience uncontrolled releases that could otherwise lead to overcharging of the dispenser and potentially dangerous situations.

How to Determine the Right Pressure for Your Whipped Cream Charger?

The first thing we recommend you do is to go through the instructions provided by the manufacturer of your whipped cream dispenser. They may provide specific recommendations for the right pressure for your whipped cream charger.

The following are the quick and easy steps you need to follow to learn how to use a 615g nitrous oxide tank with a pressure regulator.

What You Need

Steps to Follow

Prepare Your Ingredients

You can choose to only use heavy cream to create whipped cream or make the recipe more interesting by adding a sweetener and flavor. The exact amount of whipped cream you want to create depends on your recipe and the size of your dispenser. Set the whipping cream mixture aside and move to the second step.

Fill Your Dispenser with Ingredients

Make sure your dispenser is clean and dry. Then remove the head from the dispenser bottle and set it aside. Fill the appropriate amount (portions) of the whipping cream mixture you prepared into the dispenser bottle. Reattach the dispenser head and connect a decorator tip to the nozzle adaptor.

Set Up the Pressure Regulator

It is not a must but it’s recommended you wear protective gloves to protect your hands from accidental frostbite. Then screw the inlet port of the pressure regulator to the nozzle of your 615g nitrous oxide tank. Attach the pressure regulator hose to the outlet port of the pressure regulator and the other end to the dispenser head.

Some dispenser heads may have a built-in screw that is not compatible with the fitting on the pressure regulator hose. If that’s the case, you will need a spanner to remove the built-in screw and attach an appropriate adaptor screw. Some screw adaptors have a snap-fit design for easy connections.

Pressurize the Dispenser Accordingly

Turn the control knob clockwise to open the nitrous oxide pressure regulator. Adjust the working pressure accordingly from 5, 6.5, 8, 10, or 12 bar depending on the amount of whipping cream mixture in the dispenser. Stick to the recommended pressure to avoid overcharging the cream whipper.

Detach the Pressure Regulator

Unscrew or detach the pressure regulator hose from the dispenser head. If you were using an adaptor screw, remove it and reattach the built-in screw. Then attach the protector cap to the built-in screw and set your pressurized dispenser aside.

Detach the inlet port of the pressure regulator from the 615g nitrous oxide tank. Secure the nozzle of the tank with the provided cap and store it somewhere safe away from children. Also, store the pressure regulator for future use.

Some Helpful Tips for Using a Pressure Regulator

The following tips should help you use a nitrous oxide pressure regulator safely and effectively.

Choose a Regulator that Meets the Required Safety Standards

Don’t just buy any N2O pressure regulator you come across on the market. Make sure you do a little more research and confirm that the regulator meets the required safety standards. The model you choose should be able to restrict the flow of gas when the pressure exceeds the appropriate level.

Choose a Regulator that Comes with Additional Accessories

In addition to the pressure gauges, inlet port screw, hose, and outlet port screw, make sure the pressure regulator comes with an adaptor screw. You may need an adaptor screw if the built-in screw on your dispenser head is not compatible with the screw attached to the pressure regulator hose.

Start with Recommended Pressure

It’s advisable to always start with the recommended pressure for the amount of whipped cream you are making. You can adjust the pressure in small increments if the whipped cream you are dispensing is too soft or watery. But it’s also necessary to give the pressurized dispenser a few shakes to help agitate the N2O gas and the cream mixture.

Turn Off the Control Knob Before Disassembling

When you have successfully pressurized the dispenser, first turn off the control knob on the pressure regulator before disengaging the hose for the dispenser head. This helps avoid leakages and frostbite.
