Abstract

A convertible two-stage pressure regulator in which a main valve regulates fluid flow between an inlet and an outlet in response to a control pressure produced by first and second regulator valves arranged in parallel, the control pressure depending on the outlet pressure and the forces applied by compression springs to diaphragms carrying the first and second regulator valve closure elements. An electrically operated valve is provided for selectively disabling the second regulator valve whose regulator spring applies a higher force than the spring of the first regulator valve. The compressions of the regulator valve springs are coordinately varied by a manually operable selector mechanism for convening between natural and LP gas usages.
