Abstract
A two-stage regulator having a piston situated in a first stage for substantially reducing high pressures introduced into the regulator. The reduced pressure is exerted against the second stage that includes a plunger-actuated diaphragm that urges an actuator to open a ball valve at a selected pressure to allow fluid to flow out of the regulator at a desired reduced pressure.
