  • Patent number: 8336574
    Abstract: A regulator comprises a regulator valve and an actuator. The actuator is coupled to the regulator valve and comprises a control element for controlling the flow of fluid through the regulator valve. The actuator is additionally equipped with a pressure averaging sense tube to sense the actual pressure at the outlet of the regulator valve. The actual pressure is then supplied to a sensing element such as a diaphragm of the actuator to adjust the position of the control element. The pressure averaging sense tube includes an open sensing end and an elongated slot. The elongated slot advantageously senses and averages the pressure across the length of the sense tube to maximize the accuracy of the pressure signal supplied to the sensing element.

  • Patent number: 8286660
    Abstract: A gas regulator includes an actuator, a regulator valve, and a secondary device. Downstream pressure feedback is provided to the actuator and the secondary device via a Pitot tube disposed within an outlet of the regulator valve. The Pitot tube has a first branch having an end connected to the actuator to place the actuator control cavity and diaphragm in fluid communication with downstream pressure within the outlet for maintaining the outlet pressure at an actuator setpoint pressure. The Pitot tube also has a second branch having an end connected to the secondary device to place the interior of the secondary device in fluid communication with downstream pressure within the outlet for responding to changes in the downstream pressure when the outlet pressure diverges from a predetermined normal operating pressure range.

  • Patent number: 8256446
    Abstract: Apparatus to configure fluid regulators are described. In one example, a stem guide for use with a fluid regulator is described. The stem guide includes a body having an opening to slidably receive a valve stem and an outer surface having a plurality of circumferential seals that removably couple the body within a bore of a regulator casing and align the body with the regulator casing or a valve.

  • Patent number: 8151822
    Abstract: The present invention provides an integral cantilever monitoring device for a regulator having a positionable vent port that may be disposed proximate the lowest point of the monitoring device to allow drainage of liquids accumulating within the monitoring device due to humidity and precipitation. The monitoring device may also include a connection module allowing the monitoring device to be rotated independently of the actuator and valve body of the regulator to accommodate varying installation environments. The connection module may further include an inlet port for connection to a downstream pressure feedback line when the regulator valve body and connection module portions of a primary downstream pressure feedback passage are out of alignment due to rotation of the monitoring device.
