An adjustable gas regulator allows you to adjust the pressure of gas that passes through it. This type of regulator is ideal for use in gas appliances and home brewing. It is also useful for weed burners, crab pots, and turkey fryers. It also allows you to adjust the pressure based on your needs.

Adjustable gas regulators operate by using a spring to adjust the pressure of gas. Gas enters the regulator from the inlet, which can be a LP tank or natural gas pipe. The pressure that builds up on the valve seat presses on a diaphragm and spring to regulate gas flow.

A number of factors should be considered when choosing a regulator. First, determine what kind of fluid is being used. This will affect the formula for sizing. In particular, the chemical composition of the process fluid needs to be considered. In addition, the diaphragm and seat materials should be compatible with the medium. Check the manufacturer's data sheets to make sure the regulator meets your requirements.
