Abstract: A valve has flow trim assembly that can be quickly and efficiently removed and repaired or replaced. A body section having a central through bore defines an inlet, an outlet and inner chamber or space. An upstream cap and inlet hub are disposed at the inlet of the body member, while a downstream cap and outlet hub are disposed at the outlet of the body member. An actuator stem extends into the inner chamber, while a gear train can transfer torque force applied to the actuator stem to a rotator. A first (movable) trim member is attached to the rotator and can be selectively rotated relative to a second (fixed) trim member. The first and second trim members cooperate to adjust flow opening through the valve.

Abstract: A valve having a flow trim assembly that can be quickly and efficiently removed and repaired or replaced. A body section having a central through bore that defines an inlet, an inner chamber or space, and two selectable outlets. Further the selectable outlets can direct flow in either a 90 degree “angle” orientation or at straight “in-line” orientation. An actuator stem extends into the inner chamber. A first (movable) trim member is attached to the rotator, and can be selectively rotated relative to a second (fixed) trim member. The first and second trim members cooperate to adjust flow opening through the valve. A valve bonnet that allows direct coupling of an actuator to the valve.

Abstract: A throttling valve that allows staged pressure drop increments upstream and/or downstream of a primary flow trim assembly within a valve body to help prevent cavitation and freezing effects. The flow trim assembly can be quickly and efficiently removed from the throttling valve (and repaired or replaced) without requiring disassembly of the throttling valve from a flow line or other fluid conduit, and without requiring removal of an automated actuator. A throttling valve body that allows direct mounting of actuators to the valve without the need for brackets and linkages.

Abstract: A throttling valve that allows an operator to remove and replace the flow trim of the throttling valve without disassembling and/or removing the throttling valve from a flow line, and without removing an actuator, which eliminates the need to recalibrate said actuator. The throttling valve also allows drops in fluid pressure to be staged upstream and/or downstream of a main multi-port-disc trim within the same valve body to help prevent cavitation and freezing of fluids contained within the valve. The throttling valve also allows direct connection of actuators to a valve body.

Abstract: A choke valve that allows an operator to remove and replace the flow trim of the choke valve without disassembling and/or removing the choke valve from the flow line, and without removing the actuator, which eliminates the step of recalibrating the actuator.

Abstract: A protective cap assembly for a pressurized valve adapted to detect a leak therethrough. In accordance with various embodiments, the cap assembly includes a body adapted for placement in fluid communication with the valve, and a sensory indicator supported by the cap assembly body to provide human sensory indication of pressurized fluid leaking from the valve in its closed position. In various embodiments, the sensory indicator can be a whistle that makes an audible sound, a light emitting device that emits a visible light, or both. In further embodiments, the cap assembly body can be coupled to the vent conduit via a tether, and ejected responsive to exhausted pressurized fluid when the valve transitions to the open position. The displaced cap assembly body serves as a visual indication that the valve has opened.

Abstract: Apparatus and method for generating electrical power through the reduction of a wellhead pressure. In accordance with various embodiments, a wellhead coupled to a subterranean formation supplies a first conduit with pressurized natural gas at a first pressure. A turbine receives the pressurized natural gas and induces a pressure drop in the gas as the gas induces mechanical rotation of the turbine. A mechanical linkage is coupled to the turbine, and an electrical generator is coupled to the mechanical linkage. The electrical generator generates electrical power responsive to the mechanical rotation of the turbine. The turbine and the electrical generator are operated to maintain an exit pressure of the pressurized natural gas at a predetermined second pressure less than the first pressure.

Abstract: A valve seat assembly for a pressure relief valve in which a valve member is biased against a valve seat to a closed position and movable away from the valve seat to an open position when inlet fluid pressure reaches a predetermined threshold value, the valve seat assembly having a seat body with an internal bore and positioned to abut the valve member when moved by the spring to the closed position. An insert member is disposed in the seat body to extend between an upper end of the seat body and a resilient member supported by the seat body for resiliently pressing against the insert member, the upper end of the insert member supporting the valve seat to seal with the valve member.

Abstract: An illuminated tongue depressor is formed by an elongated relatively narrow body having a handle end portion containing a battery and a proximal end portion having a curvature conforming to the larynx defining a convex top surface and a concave ventral surface having a friction inducing antislip texture adjacent its proximal end. A lamp imbedded in the top surface is connected with the battery by wiring through a switch. A sanitary disposable sheath envelopes the proximal end portion of the body.

Abstract: A dual pressure relief valve selector is formed by a Y-shaped tubular body having an inlet port at its stem position connected with a vessel or a line to be monitored. Each leg of the Y-shaped housing is connected in fluid communicating relation with a safety relief valve. A spring and fluid flow biased open flap valve and valve seat is contained by each leg of the Y-shape adjacent the inlet of the respective relief valve. A pinion journalled by the housing moves a rack to and fro between the flap valves for normally maintaining one of the flap valves in closed position and isolating the relief valve downstream from the closed flap valve.
