Types of BBQ Regulators and Their Basics

LPG (propane) gas regulators regulate the pressure at which the LPG is delivered from the gas bottle to the BBQ (barbecue or rotisserie grill).The regulator screws directly into the gas bottle whilst the gas hose is attached to the BBQ.

The regulator and hose assembly will deteriorate with age. Replacing it every 5 years is good safety practice. It is good practice to perform soapy water leak test every time you disconnect and reconnect the regulator.

A BBQ regulator is a vital component of the rotisserie kit. Basically, the regulator controls the flow of gas into the kit at the correct pressure.

BBQ’s come in all different sizes and shapes from 27mm to standard propane or 20/21mm clip on butane regulators.  With BBQ regulators, it is important that this is visually inspected on an annual basis.

BBQ regulators have a diaphragm, which is a flexible rubber disc that responds to pressure changes and functions to regulate the flow of gas at the proper pressure. 

The diaphragm works in tandem with springs and other parts within the regulator. 

It also works in conjunction with the regulator vent which allows the diaphragm to move freely.

If the vent is obstructed, the diaphragm will not operate properly.

Standard bbq regulators for propane are the most commonly sold in UK.Propane is a far hotter burning gas and people prefer to use this for BBQ’s and other leisure applications. The main seller is the 27mm bbq propane gas regulator in UK.

One of the other popular gas regulators is the standard screw in regulator connected with POL inlet and hose nozzle outlet to suit 8mm hose. This has a 37mbar operating pressure and will suit all cylinders with a POL (a type of gas valve) valve connection. The gas regulators are also available with a user friendly handwheel POL connection eliminating the need for a spanner connection.Larger 4kg/hr capacity versions of the propane gas regulators for larger applications are available with female threaded or hose connection and wall bracket as required.

If your gas regulator is continually being tripped, you may have a gas leak in your hose. Shut off the valve on the gas tank and remove the regulator and hose from the tank. Dip the regulator into a solution of soap and water and reattach the regulator and hose to the tank. Ensure the burners on the grill are in the "Off" position and turn on the valve on the tank. If there is a leak in the regulator or hose, the soap bubbles will indicate its location. Replace the regulator or hose, if necessary.
