    Abstract: A valve system includes a valve body defining an inlet, an outlet, and a flow path connecting the inlet in fluid communication with the outlet through one or more flow paths through the valve body. A poppet is slidingly engaged to the valve body for movement along an axis, between a first position allowing flow though the flow path, and a second position blocking flow the flow path. An electrical circuit makes a path through the valve body. A controller is operatively connected to the electrical circuit, configured to monitor electrical resistance of the electrical circuit and to output a signal indicative of open or closed state of the valve based on whether electrical resistance of the electrical circuit is at a first level or at a second level.

    Abstract: In accordance with at least one aspect of this disclosure, a system includes, 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 is 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 being fluidly connected to the first chamber.

    Abstract: A bleed valve for an air plenum includes a valve body having a poppet seat, a poppet supported by the valve body and movable relative to the poppet seat, and piston slideable relative to the poppet and movable relative to the poppet between an extended position and a retracted position. Gas turbine engines and methods of bleeding fluid from gas turbine engines are also described.

    Abstract: A valve according to an example of the present disclosure includes a poppet head configured to move with respect to a valve outlet of the valve. A first spring is configured to be compressed with a force generated by fluid flow through the valve, and compression of the first spring allows the poppet head to move towards the valve outlet. A second spring is configured to allow the poppet head to move toward the valve outlet when compressed. A method for controlling fluid flow is also disclosed.

    Abstract: A bleed valve includes a valve housing defining an inlet and an outlet with a flow path for fluid communication from the inlet to the outlet. A poppet head is connected to the valve housing by a primary spring and a secondary spring. The poppet head is configured for movement relative to the valve housing between: a fully open position in which the poppet head is spaced apart from the inlet to allow flow through the flow path, with the primary spring and secondary spring both expanded; a partially closed position in which the poppet head is spaced apart from the inlet but is closer to the inlet than in the fully open position, with the primary spring compressed; and a fully closed position in which the poppet head seats against the valve housing blocking flow through the flow path, with the primary spring and the secondary spring both compressed.
