Abstract: A system can include a first controllable valve configured to output a first control pressure on one or more first pressure control lines, a second controllable valve configured to output a second control pressure on one or more second pressure control lines, and a valve assembly. The valve assembly can be configured to direct the first control pressure to a first functional system and the second control pressure to a second functional system in a first state, direct the first control pressure to both of the first functional system and the second functional system in a second state, and direct the second control pressure to both of the first functional system and the second functional system in a third state.

Abstract: A method includes using two parallel electrohydraulic servo valves EHSVs with a single transfer valve to move an actuator during a normal operation mode. The method includes upon failure of one of the EHSVs, using the single transfer valve to disconnect a non-operational one of the EHSVs and continuing to move the actuator with a functional one of the EHSVs in a backup mode.

Abstract: A system includes a flow inlet conduit and a primary conduit that branches from the flow inlet conduit for delivering flow to a set of primary nozzles. An equalization bypass valve (EBV) connects between the flow inlet conduit and a secondary conduit for delivering flow to a set of secondary nozzles. The EBV is connected to an equalization conduit (EC). A pressure equalization solenoid is connected to the EC to selectively connect a servo supply pressure conduit and/or a return pressure (PDF) conduit into fluid communication with the EC. An EBV rate limiting orifice (RLO) is connected in the PDF conduit. A bypass conduit branches from the PDF conduit on a first side of the EBV RLO and reconnects to the PDF conduit on a second side of the EBV RLO. An orifice bypass valve (OBV) is connected to the bypass conduit and acts to selectively bypass the EBV RLO.

Abstract: A fiber bundle cartridge for a fiber membrane degassing system includes an inner sleeve including one or more perforations and a fiber bundle positioned radially outward from the inner sleeve. The fiber bundle has an annular shape defining a central bundle axis. The perforations of the inner sleeve define a plurality of inlets and/or outlets facing radially with respect to the central bundle axis. A fiber membrane degassing system includes a housing defining a cylindrical volume having at least one inlet and at least one outlet. The system includes at least one fiber within the cylindrical volume, where fluid flowing through the cylindrical volume from the at least one inlet to the at least one outlet flows perpendicular to a longitudinal dimension of the fiber. A method of degassing a liquid includes directing a liquid volume through a fiber bundle in a direction radial to a longitudinally extending bundle axis.

Abstract: A sensor system includes a sensor body with a proximal end and a distal end. The sensor body includes a radially extending flange positioned between the proximal end and the distal end. The radially extending flange of the sensor body includes a flange surface. A sleeve is positioned radially outward from the sensor body surrounding the proximal end of the sensor body. The sleeve has a radially extending end flange with an end surface configured to contact the flange surface of the radially extending flange of the sensor body to transfer a load between the sleeve and the sensor body.

Abstract: A fluid metering valve includes a flow circuit defined by the valve and a valve member disposed in the flow circuit, the valve member having a sealing portion and configured to be moved by a solenoid between a closed position and one or more open positions. The valve includes a seat member defining one or more fluid outlets, the seat member configured to receive the sealing portion in the closed position to seal the fluid outlets, and an internal porting path defined through the sealing portion that is configured to fluidly connect a downstream side of the sealing portion with an upstream portion of the flow circuit in the closed position to reduce the effective pressure area of the valve member.
