    Abstract: A bleed valve includes a housing with an inlet coupled to an outlet by a duct, a guide tube with an orifice fixed in the housing between the inlet and the outlet, a piston, and baffle. The piston is slideably supported on the guide tube and is movable between an open and a closed position, the duct fluidly coupling the inlet and outlet in the open position, the duct fluidly separating the inlet and outlet in the closed position. The orifice fluidly couples the inlet and outlet in the open and closed positions to move piston between the open and closed positions according to differential pressure between the bleed valve inlet and outlet. The baffle is slideably supported by the guide tube to set the differential pressure at which the piston moves between the open and closed positions. Gas turbines and differential pressure adjustment methods are also described.

    Abstract: A valve system includes a heat exchanger disposed within a heat exchanger manifold. The heat exchanger manifold has a first face defining a first flow inlet and an exhaust outlet, a second face disposed opposite the first face and defining a second flow inlet, a third face extending between the first face and the second face, and a first side and a second side disposed opposite the first side. The first side and the second side each extend between the first face, the second face, and the third face. A first torque motor assembly is mounted to the first side. A second torque motor assembly is mounted to the second side.

    Abstract: A valve assembly includes a piston housing inside a flow duct between an inlet and an outlet so as to form an annular flow passage between the flow duct and the piston housing. The piston housing is axially aligned with a center axis of the flow duct. A piston is inside the piston housing and is configured to extend downstream of the piston housing in a closed position. A spring biases the piston to the open position. A fluid chamber is between the piston and an upstream end of the piston housing. A control opening extends through the upstream end of the piston housing and fluidically communicates with the flow duct and the fluid chamber. A control piston and a control spring are inside the piston housing. The control spring biases the control piston toward a first position that obstructs the control opening.

    Abstract: A piston assembly includes a piston cross-member having a first end disposed opposite a second end. The piston assembly also includes a first cap disposed on the first end of the piston cross-member, and a second cap disposed on the second end of the piston cross-member. A slot is formed in the piston cross-member transverse to a length of the piston cross-member. An insert is disposed in the slot, wherein the insert is a wear article configured to contact a crank.
