摘要： A poppet valve is provided wherein the poppet and seat are integrally aligned to a bore within a housing of the valve. The poppet is configured to reciprocate within a guide also aligned to the bore, and a spring is provided between the guide and the poppet to bias the poppet against the seat. The poppet guide is positioned, with respect to the bore, by having an alignment portion thereof fixed in a feature of the housing in which it extends, and a second housing secures the feature in the first housing. A pilot, selectively positionable by a piston, is provided to mechanically move the poppet off of the seat.

摘要： A shuttle valve having a cage fixed in the cross bore thereof by opposed inlet adaptors extending into opposed first and second inlets is provided. A shuttle is reciprocally located in a bore in the cage, to selectively seal one of the first or second inlets from fluid communication with the valve outlet. The shuttle may be spring biased to maintain one of the inlets in the closed position without the need to apply a pressure into an inlet of the valve.

摘要： The present invention generally relates to a stacked shuttle valve. More specifically, the present invention relates to a stacked shuttle valve that is; fully reconfigurable in the field, facilitated by adding or removing stages, allowing the total number of stages in an existing shuttle stack to be varied in order to suit the application requirement; fully serviceable in the field, facilitated by the installation of new shuttle and seat components shuttle components, without requiring the full dismantling of the shuttle stack and body replacement; spring biased at each stage within the stack by utilizing a small conical coil shuttle spring; leak tight shuttle without the need to coin the metal to metal adapter seal by utilizing a radius shaped shuttle seat; uses shuttle and seat components that are interchangeable with the single shuttle assembly; and capable of greater flow rates.

摘要： A dynamic variable orifice includes a housing within which are located a rotor having at least one opening extending therethrough, and at least one seat ring, having an opening therethrough, biased thereagainst. In response to a pressure spike occurring at the inlet of the dynamic variable orifice, the rotor moves axially and rotationally in the housing, to selectively align the opening in the rotor with the opening in the seat ring.
