Abstract: A ball valve includes a housing and has an inlet port, an outlet port and a central ball chamber. A ball member is received within the ball chamber and has a shaft connected to a motor such that the ball member can be rotated. The ball member is movable between a closed position at which it blocks fluid connection between the inlet port and the outlet port and to an open position at which a central passage in the ball member communicates the inlet port to the outlet port. A seal is mounted for movement with the ball member to provide a seal against the housing. A ball valve system is also disclosed.

Abstract: A transfer valve includes a spool comprising a first circumferential flow channel at a first axial position of the spool and a second circumferential flow channel at a second axial position of the spool. The first circumferential flow channel and the second circumferential flow channel have different circumferential positions and are defined only partially circumferentially, and a sleeve disposed over the spool. The sleeve includes at least three flow windows defined through the sleeve at an axial position of the sleeve, each flow window having different circumferential positions on the sleeve. The spool is configured to translate within the sleeve between a first position and a second position. The first circumferential flow channel of the spool is configured to fluidly connect a first plurality of the at least three windows in the first position, and the second circumferential flow channel is configured to connect a second plurality of the at least three windows in the second position, wherein the first plurality of windows is different by at least one window from the second plurality of windows.

Abstract: A fuel system for a turbomachine includes a minimum pressure and shutoff valve (MPSOV) disposed between a fuel source and a fuel nozzle of a fuel system and configured to move between an opened position wherein fuel can flow to the fuel nozzle, and a closed position wherein fuel is prevented from flowing to the fuel nozzle, and a shutdown signal valve (SDSV) operatively connected to the MPSOV and configured to selectively supply a shutdown pressure to the MPSOV in a shutdown state such that the shutdown pressure forces the MPSOV to the closed position.

Abstract: A system includes a first electrohydraulic servo valve (EHSV) configured to be in fluid communication with a pressure supply and with a pressure return. The first EHSV includes a first actuator extend line and a first actuator retract line. A second EHSV is configured to be in fluid communication with the pressure supply and with the pressure return. The second EHSV includes a second actuator extend line and a second actuator retract line. An actuator includes an extend chamber in fluid communication with both of the first and second extend actuator lines, and a retract chamber in fluid communication with both of the first and second retract actuator lines for extending an end effector when the first and second EHSVs pressurize the extend chamber, and for retracting the end effector when the first and second EHSVs pressurize the retract chamber.
