    Abstract: A valve is provided. The valve includes a body defining an interior and apertures, additional bodies each having opposed, open ends and being respectively coupled to each of the apertures at one of the respective open ends to define a flow path through each of the additional bodies and into the interior and a valve member. The valve member is disposable in first and second positions in the interior. In the first position, the valve member fluidly couples pairs of the additional bodies with one another via first combined flow paths that crisscross through the interior. In the second position, the valve member fluidly couples different pairs of the additional bodies with one another via second combined flow paths that are substantially parallel through the interior.

    Abstract: A controller for an inline valve includes a manifold seating a set screw and has a reference fluid port, a control fluid port, and an actuator fluid port. A selector is movable within the manifold between a first position and a second position, the reference fluid port in fluid communication with the actuator fluid port in the first position, the control fluid port in fluid communication with the actuator fluid port in the second position. A biasing member is arranged between the selector and the set screw and urges the selector towards the first position. The set screw extends through an exterior of the manifold for adjustment of differential in pressures at the reference fluid port and the control fluid port responsive to which the selector moves between the first position and the second position. Inline valves and methods of controlling fluid flow through inline valves are also described.

    Abstract: An assembly includes a housing along a fluid line through which gas can flow with the housing having an annular shape, a housing groove extending circumferentially around a radial interior, and a sense hole adjacent the housing groove in a bottom side of the housing; and a piezometer ring disposed within the housing groove and coaxial with the housing. The piezometer ring includes a ring groove extending circumferentially around a radially outer side adjacent the housing and a plurality of ring holes extending radially through the piezometer ring with the plurality of ring holes including two bottom holes closest to the bottom side of the housing that are spaced farther apart from one another than from adjacent holes of the plurality of ring holes.

    Abstract: An inline valve includes a sliding piston having a radially outer stop portion with a forward end. A radially inner sliding portion is connected to the radially outer stop portion by an arm. A housing includes an outer housing body surrounding the piston. The housing has a stop surface selectively in contact with the forward end of the radially outer stop portion of the piston to block flow for a housing inlet to a housing outlet. The radially inner sliding portion slides on a support tube. At least a portion of the radially inner sliding portion is formed of a first material having better wear resistance than a second material forming the outer stop portion of the piston. The second material has a greater resistance to high temperature and pressure than the first material. A vent valve for a compressor is also disclosed.

    Abstract: A pneumatic controller includes a manifold, a selector, and a biasing member. The manifold has a low pressure port, a high pressure port, an actuator port, and a vent. 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 is supported within the manifold and urges the selector towards the first position, wherein the low pressure port is in fluid communication with the vent in both the first position and the second position to cool the biasing member with low pressure fluid received at the low pressure port. Inline valves, gas turbine engines, and methods of controlling fluid flow through inline valves are also described.
