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.

Apparatus are configured to monitor lifespan of parts on a pressure regulator. These configurations may include sensors that generate signals in response to movement of parts on the pressure regulator. Processing circuitry can process the signals to identify data that corresponds to deflection of a spring inside of the pressure regulator. This data may correlate with duty cycle of a diaphragm. In one implementation, utilities can use the duty cycle to gauge useable lifespan of the diaphragm as well as other operating conditions that may prevail on the pressure regulator.

A vent limiting device adapted to be operably coupled to an exhaust vent of a fluid regulator. The vent limiting device includes a housing, a poppet disposed in the housing, and a retaining element arranged to retain the poppet in the housing. The housing has a fluid passageway extending between a fluid inlet and a fluid outlet. The poppet is movably disposed in the housing, responsive to pressure at the fluid outlet, to control fluid flow through the fluid passageway. The housing includes one or more retaining features that engage the retaining element to retain the retaining element in the housing.

A pressure regulating device including a valve body, an actuator assembly coupled to the valve body and including a diaphragm, a valve seat disposed in the valve body, a control assembly operatively connected to the diaphragm to move responsive to movement of the diaphragm, and a travel stop. The control assembly includes a control element that is movable, relative to the valve seat, between an open position, wherein the control element is spaced from the valve seat, and a closed position, wherein the control element sealingly engages the valve seat. The travel stop is configured to engage the control element to stop movement of the control element upon reaching the open position. The travel stop is adjustable to change the open position of the control element, such that a wide open flow capacity of the pressure regulating device can be adjusted.

A gas pressure reducer with a safety function in the case of under-pressure includes a lever having a first portion pivotally mounted on a body about a first axis and adapted to seal the gas intake, and a second portion pivotally mounted on the first portion about a second axis and cooperating with a finger secured to a flexible diaphragm.

Example embodiments relate to a gas-pressure regulator having an inlet, an outlet, a housing, a diaphragm, a control chamber and a discharge chamber. The inlet and the outlet each open onto the control chamber, wherein the diaphragm partially delimits the control chamber. A passage between the control chamber and the discharge chamber is open in one position of the diaphragm. A movable limiting element limits a movement of the diaphragm in one direction.

Actuating device for process valves (2) comprising a housing (22), comprising two housing parts (24, 26) and an actuating membrane member (20) sealingly mounted between housing parts (24, 26) and moveable in strokes which, on the one hand, forms together with the housing a pressurizeable working chamber (28) and, on the other hand, is loaded by at least one return spring (32) such that, in the unpressurized state, the actuating membrane member (20) is brought into a predefined position by means of the pre-tension of the return spring (32), wherein the actuating membrane member (20) is adapted to be connected to a valve shaft (18) connected to the valve body (16) of the process valve (2). A coupling installation (64) is provided having coupling parts (66, 68) arranged on both sides in the direction of the lifting movement of the actuating membrane member (20), which coupling parts are adapted to a connection (70) an the valve shaft (18) such that the connection of the valve shaft (18) with the actuating membrane member (20) is carried out by a one-sided mounting, wherein the valve shaft (18) is adapted to be connected to each of the coupling parts (66, 68) of the coupling installation (64). On the actuating device (2) a distance measuring system (48) is arranged, which comprises a connection (72) which is adapted to be connected to each of the coupling parts (66, 68) of the coupling installation (64) by means of a one-sided mounting, wherein the coupling parts (66, 68) are constructed in analogy to the corresponding connections (70, 72) for selectively fastening of the valve shaft (18) or the distance measuring system (48) to the coupling installation (64).

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.

A dielectric fitting for a pressure regulator includes a flange adapted to be disposed next to a housing of the pressure regulator, an isolator plate disposed next to the flange and adapted to be disposed between the flange and the housing, and an isolator cover disposed between the flange and the isolator plate to electrically isolate the flange from the housing.

Device(s) and techniques determine if a gas regulator supplying gas at a regulated pressure to a gas meter (e.g., the gas meter of a house or business) within a gas distribution system has one or more lock-up failure events or venting events, wherein gas is vented to the atmosphere. In an example, a sensor obtains information indicating a relative position of a stop stem of a gas regulator and a diaphragm pin of the gas regulator. As pressure increases within the regulator, the diaphragm pin moves toward and/or touches the stop stem. The gas pressure increase may result from debris in the regulator that prevents a valve from fully closing. A signal may be sent from the regulator and/or associated gas meter. The signal may contain information based at least in part on data from the sensor, and which may indicate a lock-up failure event or a venting event by the gas regulator.
