ABSTRACT:
The regulator of the invention includes a pressure builder inlet, economizer outlet and a pressure builder outlet/economizer inlet. A valve is moved in response to the pressure of the gas head in the tank to connect the pressure builder outlet/economizer inlet with either the pressure builder inlet or economizer outlet. As a result, the single dual-function regulator of the invention allows gas to be delivered from either the gas head or the liquid body as determined by the pressure of the gas head. A manual pressure build up valve is provided to allow isolation of the pressure build up system.
