1. 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,
wherein the second moveable member is configured to move from the first position to the second position of the second moveable member when a pressure of fluid in the first chamber exceeds a predetermined biasing force of the first biasing member; and
a shuttle valve disposed in a shuttle chamber configured to move between a first position and a second position of the shuttle valve, the shuttle chamber fluidly connected to the biasing chamber, wherein in the second position of the second moveable member, the shuttle valve is in a first position of the shuttle valve and fluid is allowed to enter the biasing chamber on a second side of the third moveable member to move the third moveable member to the second position of the third moveable member.
