The regulator truly is the heart of an LP-Gas installation. It must compensate for variations in tank pressure from 8 to 250 psig (0,55 to 17,2 bar) and deliver a constant outlet pressure of LP-Gas typically at 11-inches wc (27,4 mbar) to consuming appliances. The regulator must deliver this pressure despite the intermittent use of the appliances.

In propane service, NFPA 58 requires Two-Stage regulation on all fixed piping systems that serve 1/2 psig (34,5 mbar) appliance systems (normally operated at 11-inches wc (27,4 mbar) pressure). Two-Stage regulation produces a nearly constant pressure to the appliance and can result in a more efficient LP-Gas operation for the dealer resulting in less maintenance and fewer installation call-backs. With properly selected regulators, the large internal relief valve provides 2 psig (0,14 bar) overpressure protection as required by NFPA 58.
