Abstract: An interchangeable orifice wellhead system is disclosed which comprises a flow control valve comprised of a male union, a female union, a valve cap, and an orifice plate. The orifice plate can include a display tab, which visually communicates to the technician the size of orifice plate aperture. Orifice plates having different size apertures can be interchanged within the same flow control valve. In some embodiments, the male union of the flow control valve can be machined or interchanged with another male union to be used with different size orifice plates.

Abstract: An adjustable orifice valve system is disclosed which comprises an iris valve to control flow rate through the system, and a slide valve to prevent leaks through the system. Both valves can be adjusted through a gear train manually via a handle and/or automatically via a motor. When the iris valve is in a minimally open configuration, the gear train engages the slide valve to permit or disallow flow through the slide valve. When the iris valve is in a partially or maximally open configuration, an opening in the slide valve is aligned with the flow axis of the system to permit uninhibited flow through the slide valve. The position of the handle can indicate aperture size of the iris valve and/or position of the slide valve. In some embodiments, a pressure transducer and/or gear position sensor can provide determination of flow rate through the valve system.

Abstract: A multi-orifice plate flow valve system is disclosed which comprises a flow control valve including a multi-orifice plate and a plurality of gear wheels. The flow rate through the valve system can be adjusted through a gear train manually via a handle and/or automatically via a motor. Orifices having different size apertures can be rotated into the transport path within the same flow control valve. The multi-orifice plate can include setting indicators, which visually communicates to a user the size of orifice aperture in the transport path. In some embodiments, a pressure transducer and/or gear position sensor can provide determination of flow rate through the valve system.

Abstract: A gas flow control valve comprising coupling means for coupling to a measurement tube, wherein the coupling means are compatible with existing means for coupling valves to the measurement tube, means for directing gas from a well head through the gas flow control valve and out of an exit port, means for finely tuning the flow rate of gas passing through the flow control valve comprising, means for longitudinally translating a valve needle via rotation of a rotating assembly, wherein the valve needle comprises a tapered portion and a shoulder, wherein the tapered portion of the valve needle comprises a truncated cone which increases in diameter in the direction of gas flow, and means for visually indicating the longitudinal position of the gas flow control valve.
