    Abstract: A pneumatic controller for an inline valve includes a manifold with a set screw seated within it, a selector, and a biasing member. The manifold has a low pressure port, a high pressure port, and an actuator port. The selector is movable within the manifold between a first position and a second position, the low pressure port in fluid communication with the actuator port in the first position, the high pressure port in fluid communication with the actuator port in the second position. The biasing member urges the selector towards the first position with a biasing force and is spaced apart from the selector to limit eccentric force exerted on the selector. Inline valves and methods of controlling fluid flow through inline valves are also described.

    Abstract: An inline valve includes a valve body, a valve member, and a control manifold. The valve body has an exterior, an inlet, and an outlet. The valve member is supported within the valve body and is movable between a first position and a second position. The inlet in fluid communication with the outlet while the valve member is in the first position and the inlet fluidly separated from the outlet while the valve member is in the second position. The control manifold is supported by the valve body, has a reference fluid port and a control fluid port, and is in pneumatic communication with the valve member through the valve body exterior to passive movement of the valve member according to pressure at the valve body inlet. Gas turbine engines and methods of controlling valves are described.

    Abstract: Disclosed is a method of applying a biasing force against a piston in a valve as the piston moves along a piston stroke axis in a first direction and an opposing second direction, the piston having a first axial end that is a distal end of the piston, the method including: moving the piston along a piston stroke axis in the first direction and the opposing second direction, wherein while moving the piston along the piston stroke axis: applying a first biasing force in the second direction against the first axial end of the piston from a first spring, and applying a second biasing force in the second direction against the first spring from a second spring.

    Abstract: A pneumatic controller includes a housing, a piston located in the housing and movable therein and a diaphragm located at the piston to isolate a first chamber of the pneumatic controller from a second chamber of the pneumatic controller. The diaphragm includes a first diaphragm surface, a diaphragm opening extending through the diaphragm, and a fabric reinforcing layer to strengthen the diaphragm. A diaphragm to isolate a first chamber of a pneumatic controller from a second chamber of a pneumatic controller includes a first diaphragm surface, a diaphragm opening extending through the diaphragm, and a fabric reinforcing layer to strengthen the diaphragm.

    Abstract: A pressure relief valve controller (PRVC) includes a housing having a spring, a spring seat connected to the spring, a piston, and a portion of which is disposed between the spring seat and the piston, wherein one or more grooves and/or protrusions are disposed on at least one of the spring seat or the piston. The diaphragm can conform to the one or more grooves of the spring seat thus preventing diaphragm rupture due to excess pressure without affecting calibrations of current PRVCs.
