  • Fluid pressure regulator with reverse flow capability
    Patent number: 10359123
    Abstract: A fluid pressure regulator includes a housing having an inlet and an outlet, a valve assembly disposed in the housing, and one or more check valves disposed within the housing. The one or more check valves may be closed when a regulator inlet pressure is greater than a regulator output pressure. When the regulator output pressure is greater than the regulator input pressure, the one or more check valves may open and flow may occur from the outlet of the fluid regulator to the inlet of the fluid regulator, even if the valve assembly is in a closed position.
