Inventors:

- Houston TX, US
Andy PATTERSON - Katy TX, US

International Classification:

F16K 11/07
F16K 31/122
F16K 25/00

Abstract:

A directional control valve having low or no interflow, minimal parts, and configured for easy repair, is provided. In one embodiment, a seat is slidingly sealably movable with respect to opposed plates, such that an inlet in one of the plates communicates with an internal volume of the seat, and by selectively positioning the seat with respect to one or more outlets in a second of the opposed plates, the inlet can be placed in communication with an outlet, or isolated from the one or more outlets.

Inventors:

- Houston TX, US
Andy PATTERSON - Katy TX, US

International Classification:

F16K 11/07
F16K 31/122

Abstract:

A directional control valve for selectively communicating a valve outlet to one of a vent port and a pressure supply port includes a poppet extending through a cage. Relative positioning of the poppet to the cage selects which of the vent and pressure supply port is communicated to the valve outlet. The poppet position relative to the cage is provided by supplying fluid pressure to one of the opposed sides thereof, and the poppet latches with the cage so that the fluid pressure on one of the sides of the poppet need not be maintained to maintain the poppet position in the valve.

International Classification:

G05D 16/10
E21B 33/064

Abstract:

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.

Abstract:

A subsea pressure regulator includes: a spring housing; a spring disposed therein; a body having a bore formed therethrough and inlet and outlet ports; drive and balance adapters connected to opposite ends of the body; drive and balance plungers; and a supply seal assembly. Each plunger has: a piston shoulder engaged with the respective adapter, a first portion in fluid communication with an outlet chamber, and a second portion in fluid communication with ambient pressure. The supply seal assembly includes a seal carrier connected to the plungers and a seal bore formed therethrough. The spring biases the seal carrier toward an open position. The drive plunger is operable to move the seal carrier to a closed position in response to sufficient pressure in the outlet chamber overcoming the spring bias.

E21B 33/06

Abstract:

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.
