Abstract: A redundant sealing system with secondary containment for preventing leakage of fluid along a valve shaft is provided. The system comprises a first set of dynamic seals, a second set of dynamic seals, an auxiliary barrier fluid chamber, and a barrier fluid indicator. The first and second set of dynamic seals are in spaced relation to each other a distance equal to or further than a maximum stroke length of an actuatable valve stem. The auxiliary barrier fluid chamber is interposed between the first and second sets of dynamic seals. The barrier fluid indicator has a piston in a primary barrier fluid chamber. A first face of the piston is exposed to a process fluid. A second face of the piston is exposed to a barrier fluid and inhibited from fluid communication with the auxiliary barrier fluid chamber by a dynamic seal in the first set of dynamic seals.

Abstract: An apparatus for reducing pressure spikes in a fuel line having a shut-off valve is provided. The apparatus comprises a body housing a biasing member and a moveable separation member. The body has first, second, and third chambers. The first and second chambers are coupled to upstream and downstream sides of the fuel line, respectively. The third chamber is coupled to a return line. When the shut-off valve is open, the separation member is biased toward the first chamber and separates the first and second chambers. When the shut-off valve is closed, the separation member expands the first chamber and places it and the third chamber in fluid communication once the separation member has gained a significant speed. The expanded first chamber accumulates fuel and the third chamber accumulates and vents the fuel such that transient pressure spikes are reduced and unlikely to damage a turbine system.

Abstract: An electrical actuator (10) is particularly suited for driving a wellhead valve (12) for regulating the flow of natural gas from a production well (16). The electrical actuator (10) can be driven using the existing local power supply (24) in wellhead valve systems, typically a solar panel (24) and a battery (26). The electrical actuator (10) may include a gear reduction train (76), a brake (78) and a manual input override (80) with clutch protection. The electrical actuator (10) can be configured in three different operational modes that provides a predetermined position upon power loss including fail-bias fixed, fail open and fail bias closed.
