20080257427 | Service Regulator with Improved Boost Performance - A regulator comprises a regulator valve and an actuator. The regulator valve comprises a valve body equipped with a customized valve port. That is, the valve seat is designed to have a customized seat height depending on a diameter of an orifice through the valve port, a longitudinal dimension of an orifice through the valve port, and/or a flow capacity of the valve port. Such a design advantageously maximizes the efficiency at which gas flows through the regulator. The actuator is coupled to the valve body and comprises a valve disc disposed within the valve body and adapted for displacement between a closed position engaging the valve seat and an open position spaced from the valve seat. | 10-23-2008 |
20080258095 | Adjustable Disc Mechanism for Gas Regulator - A gas regulator comprises an actuator and a valve body, wherein the actuator includes a valve disc with a cylindrical shroud that extends beyond the valve disc to direct the flow of fluid through the regulator toward the outlet of the valve and away from the actuator. This configuration advantageously reduces the amount of pressure drop experienced by the actuator during normal operation, thereby minimizing a phenomenon known as “droop.” At least in one embodiment, the shroud can be adjustable and/or removable to allow the regulator to be tuned for specific applications. | 10-23-2008 |
20080258096 | Gas Regulator Flow Boost Cartridge - A gas regulator includes an actuator, a valve, and a cartridge disposed within the valve to advantageously direct, or “boost,” fluid downstream and away from the actuator under normal operating conditions, thereby increasing the operating efficiency of the regulator. The cartridge includes a first portion with a first diameter and a second portion with a second diameter that is greater than the first diameter. During normal operation, the first portion receives a valve disc of the actuator within generally tight tolerances such that the valve disc and the cartridge restrict fluid communication between the valve and the actuator. This directs or “boosts” the gas toward the outlet of the valve. Additionally, during a relief operation, the second portion of the cartridge receives the valve disc to allow the free flow of gas to the actuator. | 10-23-2008 |
20080258099 | Service Regulator Vent - A fluid regulating device comprises an actuator with upper and lower housing components.

The first casing and a first side of the loading diaphragm define a first chamber and the second casing and a second side of the loading diaphragm define a second chamber. A relief valve assembly is coupled to the loading diaphragm. The relief valve assembly includes a relief valve seat having an aperture that forms a passageway to fluidly couple the first chamber and the second chamber and a relief valve plug movably coupled to the relief valve seat. The relief valve plug is to move away from the relief valve seat to a bleed position to allow the flow of fluid between the first chamber and the second chamber in response to an outlet pressure substantially greater than a pressure at which the loading regulator enters a lock-up condition. | 06-17-2010 |
20140090724 | PILOT-OPERATED REGULATOR WITH BALANCED PORT - A fluid regulating device includes a regulator valve, an actuator and a pilot regulator valve assembly. The pilot regulator valve assembly provides a pressure load to a surface of a diaphragm of the actuator in response to changes in downstream pressure being applied to the opposite surface of the diaphragm. An upper cavity of the pilot regulator valve assembly is in fluid communication with a control cavity of the actuator, allowing both the actuator diaphragm and the pilot regulator valve assembly diaphragm to simultaneously sense pressure variations within the cavities. As the downstream pressure varies, the diaphragms of both the actuator and the pilot regulator valve assembly displace to regulate the downstream pressure and the pilot regulator valve assembly maintains a load pressure. The regulator further includes a balanced regulator valve applying a balancing force to offset a force of upstream pressure on a balanced valve plug. | 04-03-2014 |
