Claim 12:
13. A system, comprising:
a first moveable member disposed in a first chamber configured to move between a first position and a second position of the first moveable member to allow or prevent fluid from passing from an inlet of the first chamber to an outlet of the first chamber;
a second moveable member disposed in a second chamber configured to move between a first position and a second position of the second moveable member to allow or prevent fluid from entering a biasing chamber, the second chamber fluidly connected to the first chamber;
a first biasing member disposed on a first side of the second movable member configured to bias the second moveable member to the first position of the second moveable member to prevent fluid from entering the biasing chamber;
a third moveable member disposed in the biasing chamber and operatively connected to the first moveable member via a mechanical linkage, the third moveable member configured to move between a first position and a second position of the third moveable member;
a second biasing member disposed on a first side of the third moveable member configured to bias the third moveable member to the first position of the third moveable member and the first position of the first moveable member to allow fluid to pass from the inlet of the first chamber to the outlet of the first chamber;
a first fluid line configured to provide compressor bleed air from a compressor to ambient via the first chamber;
the valve system disposed in the first chamber of the first fluid line to selectively control a flow of the bleed air to ambient based on a position of the first, second, and third moveable members; and
a second fluid line selectively fluidly connected to the biasing chamber configured to provide a secondary fluid to the biasing chamber in the second position of the second moveable member.
