Patent number: 9297465Abstract: 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.Type: GrantFiled: October 1, 2012Date of Patent: March 29, 2016Assignee: EMERSON PROCESS MANAGEMENT REGULATOR TECHNOLOGIES, INC.Inventors: Jason Scott Mevius, James Chester Hawkins, Paul Richard Anderson

Patent number: 8944089Abstract: A balanced port control assembly includes a control element with a valve plug coupled to a valve stem and a pressure sensing labyrinth defined at least partly by the valve plug. The pressure sensing labyrinth provides for fluid communication between a sealing surface of the valve plug and a balancing diaphragm carried internally of the control element. The pressure sensing labyrinth includes at least one pressure sensing passage extending from the sealing surface and into the valve plug along a central longitudinal axis of the control element. So configured, fluid pressure resident on the sealing surface of the valve plug is also resident on the balancing diaphragm such that equal and opposite forces are applied to the control element.Type: GrantFiled: October 24, 2012Date of Patent: February 3, 2015Assignee: Emerson Process Management Regulator Technologies, Inc.Inventors: Tung K. Nguyen, Jason Scott Mevius, Biao Zhou

Patent number: 8939167Abstract: A pressure relief assembly may include an actuator stem having a plurality of retaining grooves. A relief plate may be operatively connected to the actuator stem and a diaphragm plate may be operatively connected to the actuator stem. A diaphragm may be least partially disposed between the relief plate and the diaphragm plate. A relief spring seat may be releasably attached to the actuator stem at one of the plurality of retaining grooves. The relief spring may be adjusted by moving the attachment point from one retaining groove to another retaining groove.Type: GrantFiled: September 27, 2012Date of Patent: January 27, 2015Assignee: Emerson Process Management Regulator Technologies, Inc.Inventor: Jason Scott Mevius

Patent number: 8840349Abstract: An adjusting screw configured to be adjustable by multiple different tools is described. An example adjusting screw includes a cylindrical body portion having a first end, a second end, and an outer curved surface. The example adjusting screw also includes a first raised portion on the first end and offset from a longitudinal axis of the cylindrical body and a second raised portion on the first end and offset from the longitudinal axis of the cylindrical body and opposing the first raised portion. Each of the first and second raised portions is configured to engage a first socket to turn the cylindrical body about the longitudinal axis. Additionally, the first and second raised portions are configured to engage a second socket larger than the first socket to turn the cylindrical body about the longitudinal axis.Type: GrantFiled: April 7, 2008Date of Patent: September 23, 2014Assignee: Fisher Controls International, LLCInventors: Jason Scott Mevius, Gregory Lawrence Foust, James Chester Hawkins

Publication number: 20080256754Abstract: An adjusting screw configured to be adjustable by multiple different tools is described. An example adjusting screw includes a cylindrical body portion having a first end, a second end, and an outer curved surface. At least a portion of the outer curved surface has threads to engage an internally threaded opening. The example adjusting screw also includes a first raised portion on the first end and offset from a longitudinal axis of the cylindrical body and a second raised portion on the first end and offset from the longitudinal axis of the cylindrical body and opposing the first raised portion. Each of the first and second raised portions is configured to engage a first socket to turn the cylindrical body about the longitudinal axis. Additionally, the first and second raised portions are configured to engage a second socket larger than the first socket to turn the cylindrical body about the longitudinal axis.Type: ApplicationFiled: April 7, 2008Publication date: October 23, 2008Inventors: Jason Scott Mevius, Gregory Lawrence Foust, James Chester Hawkins
