Nearly all gas burning appliances require a regulator which reduces and controls the pressure from a cylinder of gas. Most domestic appliances run at 'low pressure' which is between 28 and 37 mbar. Blowtorches and many industrial appliances run at high pressure - typically 1-2 bar (15-30 psi). In choosing a regulator you need to consider 3 things:

• which gas is being used - propane or butane
• what pressure is required for the appliance - this would then the the required outlet pressure for the regulator
• what is the flow of gas required by the appliance - you then need to ensure that the capacity of the regulator is high enough to supply this

Two ranges of regulators:

• Bullfinch made high performance, high pressure regulators

• Other quality regulators for high and low pressures and changeover device
