    Abstract: A starter air valve comprising: a housing comprising an inlet at a first end, an outlet at a second end opposite the first end, and a center portion between first end and second end, the outlet being fluidly connected to the inlet through a fluid passage; a first piston located within the housing between the first end and center portion, the first piston comprising: a first cupped portion configured to form a first chamber with the housing proximate the first end; and a second piston located within the housing between the second end and center portion, the second piston comprising: a third cupped portion configured to form a third chamber with the housing proximate the second end; wherein the pistons are configured to regulate airflow through the fluid passage by adjusting at least one of a first pressure within the first chamber and a third pressure within the third chamber.

    Abstract: In accordance with at least one aspect of this disclosure, a system includes a first wire configured to electrically connect a valve stop to a voltage source, a second wire configured to connect a valve pin to a negative terminal of the voltage source, such that the valve stop, and a valve flap operatively connected to the valve pin are configured to create a closed valve circuit when the valve flap is in a fully open position with the valve flap contacting the valve stop, and an open valve circuit when the valve flap is not in the fully open position. A meter is operatively connected to measure an electrical characteristic of the valve circuit to determine when the valve flap is in the fully open position based on an open/closed status of the valve circuit.

    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 system includes a starter air valve with a manual override and a pressure regulating bleed valve in fluid communication with the starter air valve. The starter air valve is in fluid communication with an air turbine starter to drive motoring of a gas turbine engine responsive to a compressed air flow from a compressed air source. The pressure regulating bleed valve is operable to bleed a portion of the compressed air flow to produce a bleed controlled starter air flow to limit a motoring speed of the gas turbine engine below a resonance speed of the gas turbine engine responsive to detection of the manual override in an open position.

    Abstract: A sleeve valve includes an inlet port and an outlet port. A sleeve is movable to close flow from the inlet port to the outlet port. The sleeve valve has a sleeve biased to an open position at which it allows flow from the inlet port to the outlet port by a spring. Pressure in a pressure chamber urges the sleeve to a closed position at which it blocks flow from the inlet port to the outlet port. A line pressure conduit communicates the fluid chamber into the pressure chamber. Pressurized air is supplied to the pressure chamber through a selectively closed valve. The selectively closed valve is opened to allow the flow of high pressure air from a pressure source into the pressure chamber to move the sleeve to a closed position. A bleed air system for a gas turbine engine is also disclosed.
