Abstract: An assembly for reducing excess piping pressure in a fluid distribution system. The assembly includes a fluid regulator including a body defining an inlet, an outlet, and a fluid passageway between the inlet and the outlet, a first control element movable relative to a valve seat in the fluid passageway to control fluid flow therethrough, a valve stem coupled to the first control element, and an actuator assembly operatively coupled to the valve stem to control a position of the first control element. The assembly also includes a solenoid valve coupled to the fluid regulator at a position upstream of the outlet, the solenoid valve adapted to receive a control signal indicative of zero demand downstream of the fluid regulator, and having a second control element that is movable, responsive to the control signal, from a first position to a second position to reduce fluid flowing through the fluid passageway.

Abstract: A stabilizer cartridge for enhancing stability of a fluid regulator is provided. The stabilizer cartridge includes a body, a first disk, and a second disk. The body has a through-bore and an external flange. The first disk has one or more windows and an aperture, and is fixed on an exterior surface of the body. The second disk is slidable along the exterior surface of the body and is biased into contact with the first disk by a biasing element that is positioned between the external flange and the second disk.

Abstract: A stabilizer cartridge for enhancing stability of a fluid regulator is provided. The stabilizer cartridge includes a body, a first disk, and a second disk. The body is adapted to be disposed around a valve stem of the fluid regulator. The first disk is coupled to the body and defines one or more flow paths for facilitating pressure relief. The second disk is movably coupled to the body and is movable relative to the first disk responsive to fluid flow through the one or more flow paths of the first disk.

Abstract: A safety device for a gas distribution system includes a valve body, an upper casing attached to the valve body, the upper casing housing at least one spring. Further, the at least one spring is attached to a movable diaphragm that is exposed to gas system pressure. The valve body also includes a release element mounted within the valve body. The release element releasing a relatch plug when the device is activated to move a safety disc into contact with a valve seat to stop fluid from flowing when an overpressure or an underpressure condition is sensed.

Abstract: A fluid regulating device includes a regulator valve having an inlet, an outlet, and a valve port disposed between the inlet and the outlet. An actuator is coupled to the regulator valve and includes a valve disc that displaces between a closed position and an open position. The device also includes an overpressure protection device adapted to stop flow from the inlet to the outlet when pressure in a control cavity reaches a predetermined level. The overpressure protection device includes a sensing tube having a first end in fluid communication with the control cavity and a second end in fluid communication with the outlet. The sensing tube has a first portion extending parallel to the flow axis. One or more apertures are disposed in the sensing tube adjacent to the second end, and each of the apertures has a centerline that is perpendicular to the flow axis.

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.
