Abstract: Pressure regulators with adjustable boost bodies are described herein. An example pressure includes a valve body defining a fluid passageway and an actuator casing coupled to the valve body, the actuator casing defining a pressure sense chamber and a channel between the pressure sense chamber and the fluid passageway in the valve body. The pressure regulator includes a plug assembly including a stem, a plug, and a stem guide. The stem guide has a flange with a notch. The plug assembly includes a boost body and a tube extending through the boost body. A first end of the tube is aligned with the notch and a second end of the tube is disposed in a downstream location relative to the seat such that the pressure sense chamber is in fluid communication with the downstream location. The boost body is rotatable with respect to the stem guide.

Abstract: Balanced plug assemblies and pressure regulators having balanced plug assemblies are described herein. A pressure regulator disclosed herein includes a device body defining a fluid passageway between an inlet and an outlet. The device body defines a channel between the fluid passageway and a pressure sense chamber. The pressure regulator includes a seat in the fluid passageway, a stem having a flange, and a plug coupled to the stem. The pressure regulator also includes a stem guide disposed in the channel of the device body. The flange of the stem disposed in a balance chamber of the stem guide and divides the balance chamber into a first balance chamber portion and a second balance chamber portion. The stem guide at least partially forms a balance passage that fluidly couples the pressure sense chamber and the second balance chamber portion.

Abstract: Flame arresters and end housings for flame arresters are described herein. An example flame arrester includes an end housing. The end housing includes a pipe section having a first end and a second end opposite the first end, the pipe section having a first inner diameter along a first length between the first end and the second end. The end housing also includes a connection flange extending from the pipe section at the first end and a body flange extending from the pipe section at the second end. The flame arrester also includes a body having a third inner diameter along a second length, the third inner diameter being larger than the first inner diameter. The flame arrester also includes a flame cell disposed in the body, the flame cell having a first side, a second side, and a plurality of channels between the first and second sides.

Abstract: Valve handles and dual-valve assemblies having handles are disclosed herein. An example dual-valve assembly includes a first valve having a first shaft. The first valve has a plate with a notch. The dual-valve assembly also includes a second valve having a second shaft. The dual-valve assembly further includes a handle coupled to the first and second shafts, such that when the handle is rotated, the first and second shafts are rotated simultaneously. The handle includes a body and a flexible arm coupled to and extending from the body. The flexible arm has a lock edge sized to fit within the notch to limit rotation of the handle relative to the first and second valves.

Abstract: A control system having a first pressure regulator, a downstream fluid control device, first pilot, and second pilot. The first pressure regulator has a fluid inlet, fluid outlet, and actuator assembly with a cavity divided into a first chamber and a second chamber. The downstream fluid control device has a second fluid inlet and a second fluid outlet. The first pilot has a first setpoint and the second pilot has a second setpoint, less than the first setpoint. The first and second pilots fluidly couple the second chamber to the second fluid outlet in a first mode of operation, isolate the second chamber from the second fluid outlet in a second mode of operation, and fluidly couple the second chamber to the fluid inlet in a third mode of operation.

Abstract: A slam-shut safety assembly configured to provide redundant safety shutoff in a gas distribution system. The slam-shut safety assembly includes a valve body, a first slam-shut safety device coupled to the valve body, and a second slam-shut safety device coupled to the valve body. The valve body has an inlet, an outlet, and defines a flow path extending between the inlet and the outlet. The first slam-shut safety device is configured to block the flow path at a first position responsive to an overpressure condition or an underpressure condition. The second slam-shut safety device is configured to block the flow path at a second position responsive to the overpressure condition or the underpressure condition.
