A subsurface safety valve assembly has a valve body with an axially oriented valve bore and a valve cavity that intersects the valve bore. A disk valve member is positioned within the valve cavity and has a disk bore. A piston member is moveable between a contracted position and an extended position, such that in the contracted position the disk valve member is in a valve closed position with the disk bore offset from the valve bore, and in the extended position the disk valve member is in a valve open position with the disk bore axially aligned with the valve bore. An uphole seal member circumscribes the valve bore, forming a seal between the uphole side of the disk valve member and the valve body. A downhole seal member circumscribes the valve bore, forming a seal between the downhole side of the disk valve member and the valve body.

A system for extracting landfill gas from a landfill is provided. According to some embodiments, a control system for landfill gas extraction is provided. The control system uses a throttle to control flow of landfill gas extracted from the landfill. The throttle is actuated in use to vary the flow of gas between a well and a gas collection system, in accordance with a control algorithm that adjusts flow as a parameter in controlling gas extraction. The throttle is configured to ensure that there is at least some flow of landfill gas from the landfill to a gas output throughout operation. The extraction system provides an efficient system for landfill gas extraction, while mitigating a risk of creating undesired or unpleasant conditions and/or of violating regulations during operation.

A plug valve with adjustable actuation phases for controlling a flow rate by means of plug axial movement includes a power disk, a bearing, an inner spline, an outer spline, a valve stem, a pushing ring, a pushing fork, a plug body and a valve body. The plug body, the valve stem, the pushing ring and the outer spline are integrally formed, and are in spline connection with the power disk and the inner spline. The plug body has a special-shaped through hole in which a left portion thereof is narrow and a right portion thereof is wide. The valve body has a radial valve through hole, and the valve through hole corresponds to the plug special-shaped through hole provided at the same axial position segment, so that an actuating member for controlling actuation of a passageway is formed.

An apparatus includes a housing and at least two pipe ram systems engageable with the housing. Each of the at least two pipe ram systems comprises an actuator, a bonnet and a sealing pipe ram element. The at least two pipe ram systems are disposed on opposed sides of the housing. A carousel is disposed proximate at least one of the at least two pipe ram systems. The carousel has mounted thereon a plurality of pipe ram systems. The carousel is rotatable to orient a selected one of the plurality of pipe ram systems toward a receiving bore in the housing.
