Bottled LPG regulators are an important component for LPG appliances that use natural gas. The regulator controls the gas flow through diaphragms, seat discs, and springs. The regulator also contains a vent that allows the diaphragm to move freely. It is important to ensure that the vent is clean and free of debris.

Propane tanks are a variety of different pressures and the regulator is a crucial component for a safe, steady supply of gas for domestic appliances. Propane tank pressures can range from 10 psig to over 200 psig and a regulator can be used to maintain the correct pressure in a tank and provide a steady flow of gas to household appliances.

Propane and Butane gas regulators have different pressure ranges, so they must be installed properly to prevent injury or damage. The wrong regulator could cause serious injury or property damage. Propane and Butane gas regulators should be stamped to ensure safety. Also, new regulators are required to incorporate an over pressure shut off device.

When purchasing a bottle of LPG, you must ensure that the regulator you choose is compatible with the type of cylinder you have. This is important, because high pressure regulators can damage low-pressure appliances. A cylinder's valve has a screw thread that a regulator is designed to fit.

There are two types of bottle regulators: conventional and bolt on. The former is best for smaller bottles, such as those that hold seven to fifteen kilograms. The latter is best for bottles that are not much bigger than 4.5 kilograms.
