초록

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 th...

청구항

A pressure regulator having first and second electrically determinable states for each of a plurality of pressure ranges, the pressure range being changeable without parts replacement, the pressure regulator comprising: housing means defining fluid inlet and fluid outlet passageways and a main valve seat providing for flow between the fluid inlet and fluid outlet passageways; a main valve closure member mounted in said housing means for movement relative to the main valve seat for varying the flow between the fluid inlet and outlet passageways; a main va...
