A fluid flow control device, comprising: a valve body defining an inlet, an outlet, a gallery disposed between the inlet and the outlet, a regulator cavity disposed between the gallery and the outlet, and a bypass cavity disposed between the gallery and the outlet; a regulator flow path extending between the inlet and the outlet of the valve body via the gallery and the regulator cavity, the regulator flow path having a first effective cross- sectional area; a bypass flow path extending between the inlet and the outlet of the valve body via the gallery and the bypass cavity, the bypass flow path having a second effective cross- sectional area that is greater than the first effective cross-sectional area; a bypass valve connected to the valve body and including a bypass control assembly, the bypass control assembly including a bypass control element and a bypass biasing device, the bypass control element being movable relative to the bypass cavity of the valve body between an open position allowing fluid flow through the bypass flow path and a closed position preventing fluid flow through the bypass flow path, the bypass biasing device urging the bypass control element toward the open position such that the bypass control element only occupies the closed position when a fluid pressure in the bypass cavity is equal to or greater than a bypass set-point pressure; and characterized by a regulator connected to the valve body and including a regulator control assembly, the regulator control assembly including a regulator control element and a regulator biasing device, the regulator control element being movable relative to the regulator cavity of the valve body between an open position, which does not prevent fluid from flowing through the regulator flow path, and a closed position, which does prevent fluid from flowing through the regulator flow path, the regulator biasing device urging the regulator control element toward the open position such that the regulator control element occupies the open position until a fluid pressure in the regulator cavity of the valve body is equal to or greater than a regulator set-point pressure, wherein the regulator set-point pressure is greater than the bypass set-point pressure. a valve body defining an inlet, an outlet, a gallery disposed between the inlet and the outlet, a regulator cavity disposed between the gallery and the outlet, and a bypass cavity disposed between the gallery and the outlet; a regulator flow path extending between the inlet and the outlet of the valve body via the gallery and the regulator cavity, the regulator flow path having a first effective cross- sectional area; a bypass flow path extending between the inlet and the outlet of the valve body via the gallery and the bypass cavity, the bypass flow path having a second effective cross- sectional area that is greater than the first effective cross-sectional area; a bypass valve connected to the valve body and including a bypass control assembly, the bypass control assembly including a bypass control element and a bypass biasing device, the bypass control element being movable relative to the bypass cavity of the valve body between an open position allowing fluid flow through the bypass flow path and a closed position preventing fluid flow through the bypass flow path, the bypass biasing device urging the bypass control element toward the open position such that the bypass control element only occupies the closed position when a fluid pressure in the bypass cavity is equal to or greater than a bypass set-point pressure; and characterized by a regulator connected to the valve body and including a regulator control assembly, the regulator control assembly including a regulator control element and a regulator biasing device, the regulator control element being movable relative to the regulator cavity of the valve body between an open position, which does not prevent fluid from flowing through the regulator flow path, and a closed position, which does prevent fluid from flowing through the regulator flow path, the regulator biasing device urging the regulator control element toward the open position such that the regulator control element occupies the open position until a fluid pressure in the regulator cavity of the valve body is equal to or greater than a regulator set-point pressure, wherein the regulator set-point pressure is greater than the bypass set-point pressure.
