摘要： An actuator assembly includes an operating actuator and a holding actuator that are engageable with an operator member of a device. The operating actuation is cycled between on and off states to move the operator member in incremental steps, and the holding actuator is maintained in an active state to maintain or latch the current position of the operator member. Each of the operating and holding actuators may include one of the following: a solenoid actuator; and an actuator including one or more expandable elements, such as a piezoelectric element, a magnetostrictive element, and a heat-expandable element.

摘要： A subsurface valve with a pressure-equalizing mechanism is provided to permit pressure above and below a valve closure member to equalize prior to the opening of the valve closure member. The pressure-equalizing mechanism may be installed, for example, in the valve closure member or in an annular housing in the subsurface valve. The mechanism includes a pilot activator disposed for reciprocal movement within a pilot bore. A flow tube that is disposed for longitudinal movement with a longitudinal bore of the subsurface valve is used to shift the pilot activator within the pilot bore from a closed or sealed position to an open or equalizing position. In the open position, fluid pressure below the valve closure member is allowed to flow through a pilot passageway that establishes fluid communication between the pilot bore and a cylinder within which a pilot piston is moveably disposed. Exposure of the pilot piston to fluid pressure below the valve member moves the pilot piston within the cylinder, which in turn moves an equalizing plug that is disposed for reciprocal movement within a plug bore from a closed or sealed position to an open or equalizing position. Movement of the equalizing plug to its open or equalizing position establishes fluid communication from below the valve closure member to above the valve closure member through an equalizing passageway. Pressure above and below the valve closure member is equalized through the equalizing passageway prior to the opening of the valve closure member by further downward movement of the flow tube.

摘要： A subsurface well safety valve having a flow tube telescopically movable in the housing for controlling movement of a valve closure member. A piston and cylinder assembly actuates the flow tube and it is in communication with hydraulic control fluid on one side and a gas biasing chamber on a second side and includes a biasing spring acting on the flow tube to close the valve. A second piston is telescopically positioned in the first piston with two different sized sealing areas, one of which is exposed to hydraulic fluid and the second of which is exposed to the gas chamber. In the event of loss of gas pressure, the second piston will separate from the first piston causing hydraulic pressure equalization and failsafe closure of the valve.
