Natural Gas Regulators

Only our appliance regulators are for indoor use. All other gas regulators are for outdoor use only.

First Stage and Second Stage gas regulators are used in domestic and commercial applications.

A first stage gas regulator is often connected to one or two gas cylinder/s with pigtail/s, taking the pressure from max. 1750kPa to approximately 70kPa. A second stage gas regulator is placed further along the gas line and takes the gas pressure from approximately 70kPa to 2.75kPa.

We recommend Kosan First Stage and Second Stage regulators for high-pressure and high-volume commercial applications.

All Bromic and Cavagna dual-stage regulators come with a patented safety shut-off feature.

The safety shut-off is a mechanism that will engage in the event of gas flow greater than 140% of rated flow (e.g. regulator diaphragm failure, equipment leakage downstream). This prevents any potential emergencies and ensures safety at all times.

Manual changeover and automatic changeover dual-stage gas regulators are used for multi-LPG cylinder setups.

Once one LPG cylinder runs out, an automatic changeover regulator will automatically switch from using one gas cylinder to another. For manual changeover regulators, the user will need to manually reset the valve after the first gas cylinder runs out.

Manual changeover gas regulators mean that you are less likely to unknowingly end up with two empty gas cylinders. However, they mean that you will have to pause gas usage and switch cylinders manually.

Using an automatic changeover gas regulator means that you don’t have to pause gas usage. However, you will need to routinely inspect your set-up to ensure that gas bottles are not empty.

To suit your preferences and needs, Bromic supplies both automatic and manual changeover gas regulators.

When using the natural gas appliance regulators (item number 6160788 and 6160785) the vent is for air, not gas. (If gas can be smelt from this, there is a puncture in the diaphragm and must be replaced). The vent allows the diaphragm to move up and down to allow the gas to flow. Through the regulator. If this is blocked, the gas will either be blocked from flowing or will not be able to stop flowing depending on how the diaphragm is stuck. The yellow cap should be left on to prevent dust or insects from blocking the hole. 

Yes, the natural gas appliance regulators (item number: 6160788 and 6160785) can be installed in cupboards or outside for a BBQ.
