Abstract: Example apparatus for regulator heat transfer are disclosed. An example apparatus includes a housing including an inlet, an outlet, a first valve, and a stem disposed therein. The example apparatus includes a vortex generator disposed in the housing. A fluid is to flow from the inlet through the vortex generator. The example apparatus includes a second valve disposed in the vortex generator. In the example apparatus, the vortex generator is to generate heat prior to the fluid flowing through the second valve to the outlet. The stem is to control the first valve and the second valve to regulate an amount of the heat conveyed to the first valve.

Abstract: Fluid regulator systems having reset apparatus and methods are described herein. A fluid regulator system includes a fluid regulator including a loading chamber and a supply chamber. The supply chamber is in fluid communication with a supply fluid. The system includes a first fluid control device having a loading inlet and a loading outlet. The loading inlet receives a loading fluid from a loading fluid source and the loading outlet is in fluid communication with the loading chamber. The first fluid control device controls fluid flow between the loading fluid source and the loading chamber. A second fluid control device includes a vent inlet and a vent outlet. The vent inlet is in fluid communication with the loading outlet and the loading chamber and the vent outlet is in fluid communication with a vent. The second fluid control device to control fluid flow between the loading chamber and the vent.

Abstract: Example apparatus for regulator heat transfer are disclosed. An example apparatus includes a regulator including a body, a stem disposed therein, a first inlet and a first outlet. The regulator regulates a pressure of a fluid flowing from the first inlet to the first outlet. The example apparatus comprises a vortex generator disposed within the body to convey heat to a valve of the regulator. The stem controls the regulator and the vortex generator.

Abstract: Pressure-balanced fluid pressure regulators are described. An example fluid regulator includes a fluid flow control member disposed within a fluid flow passageway of a valve body and moves relative to a seat ring to modulate fluid flow through the fluid flow passageway. A valve stem couples the fluid flow control member to an actuator. The valve stem has a pathway to allow fluid from an inlet of the fluid flow passageway to flow across the flow control member between a first side of the flow control member and a second side of the flow control member opposite the first side to pressure-balance the fluid flow control member.

Abstract: Two-piece trim apparatus for use with fluid regulators are described. In one described example, a fluid regulator has a regulator body and a first seat ring to provide a first flow characteristic disposed within the body and defining a fluid orifice. The first seat ring is interchangeable with a second seat ring that is to provide a second flow characteristic different from the first flow characteristic. The fluid regulator also includes a first cage to provide a third fluid characteristic and removably coupled to the first seat ring. The first cage is interchangeable with a second cage that is to provide a fourth fluid flow characteristic different from the third flow characteristic. The first cage can be selectively coupled to the first seat ring or the second seat ring and the first seat ring can be selectively coupled to the first cage or the second cage.

Abstract: A regulator having a valve body defining a flow-path for a fluid and having a valve seat, an actuator casing coupled to the valve body, a control member disposed within the actuator casing and adapted for displacement relative to the valve body and the valve seat for regulating a flow of the fluid through the flow-path by moving between an open position and a closed position wherein the control member engages the valve seat, and a spring operatively coupled to the control member and biasing the control member toward the open position. The control member includes a surface facing the valve seat that is recessed. The recessed surface may be a counter-bore, or may have a convex shape, conical shape, or other appropriate recessed surface. So configured, the regulator displaced improved stability in high inlet pressure, low output pressure, high flow rate implementations.

Abstract: A pressure reducing fluid regulator having a housing with a flange including a plurality of ear-shaped protrusions is disclosed. Each of the protrusions includes at least one aperture configured to receive fastener such that the circumferential spacing between first and second fasteners is less than the circumferential spacing between the second fastener and a third fastener. The regulator includes a valve having a valve seat, a valve disc, a valve stem coupled to the valve disc and a valve guide that holds the valve stem. A lever having a first end coupled to the valve stem and a second end coupled to a diaphragm applies a force to the valve stem in a direction that is non-parallel to the longitudinal axis of the valve stem to cause the valve stem to frictionally engage the valve guide. The valve stem includes a stop that limits travel of the valve stem and disc toward the valve seat.
