An example method disclosed herein includes adjusting a packing flange nut to a position corresponding at least approximately to a free condition of a biasing assembly, coupling a first gauge member to a first flange, adjusting a first gap between a first surface of the first gauge member and a reference surface opposite the first flange to a first predetermined distance, and tightening the packing flange nut so that the first surface of the first gauge member substantially aligns with or engages the reference surface and causes a load assembly to provide a first predetermined packing stress to the valve packing when the first gauge member substantially aligns with or engages the reference surface.Type: GrantFiled: November 18, 2013Date of Patent: November 10, 2015Assignee: FISHER CONTROLS INTERNATIONAL LLCInventors: Wilbur Dean Hutchens, Randall Scott Collison, Loren Lee Bovee, David Charles Stanze

Patent number: 9140269Abstract: A seal assembly forms a barrier between a compressor's interior and exterior regions. The seals assembly includes a primary seal stage and a secondary seal stage. The primary seal stage is formed of materials chosen to effectively block flow of gas through the seal assembly. The secondary seal stage is formed of materials chosen to survive a failure of the primary seal stage.Type: GrantFiled: March 29, 2012Date of Patent: September 22, 2015Assignee: Solar Turbines IncorporatedInventor: Gordon E.

Patent number: 9121315Abstract: A passive valve assembly for an exhaust component includes a vane that is positioned within an exhaust gas flow path. The vane is pivoted from a closed position to an open position in response to exhaust gas flow overcoming a biasing force. A stop is positioned within the exhaust component and cooperates with the vane to define a closed position for the vane.Type: GrantFiled: January 14, 2008Date of Patent: September 1, 2015Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Kwin Abram, Govindaraj Kalyanasamy, Robin Willats

Patent number: 9097360Abstract: A valve for a refrigeration system includes a valve body having an inlet port, an outlet port, and walls forming a main cavity. The valve also includes a cartridge that resides within the main cavity and having a piston configured to travel in a first direction to permit fluid flow from the inlet port to the outlet port and in a second direction to impede fluid flow from the inlet port to the outlet port and a port plate configured to removably couple to the valve body to substantially close an end of the main cavity substantially enclosing the cartridge within the main cavity, the port plate including a plurality of ports, each port configured to accept at least one of various valve control elements configured to control the piston to permit or impede the fluid flow from the inlet port to the outlet port.Type: GrantFiled: April 3, 2013Date of Patent: August 4, 2015Assignee: Parker-Hannifin CorporationInventors: Steve Mesner, Anis M. Rahman, Srinivasu N. V. S. Jalluri, Brian D. Marshall

Publication number: 20150144823Abstract: A valve with a packing assembly includes a valve body assembly with a bore, a valve member moveable between an open position and a closed position, and a valve stem coupled to the valve member. A first stem packing circumscribes a portion of the valve stem, and is located in an upper bore portion of the bore. A first packing retainer has a collar that limits axial movement of the first stem packing, and also has a first retainer body defining an inner cavity. A second stem packing circumscribes a portion of the valve stem and is located in the inner cavity of the first packing retainer. A second packing retainer has a neck compressingly engaging the second stem packing, and a retainer shoulder that engages the first packing retainer. A retaining assembly is coupled with the valve body assembly for applying axial force to the second packing retainer.Type: ApplicationFiled: November 26, 2013Publication date: May 28, 2015Applicant: GE Oil & Gas Pressure Control LPInventors: Andrew Browne Helvenston, Robert Kevin Law, Mark Anthony Viator, Keith Adams, Rolando Farinas

Publication number: 20150129788Abstract: A ball valve including upstream and downstream seats and a ball having a flow opening disposed between the upstream and downstream seats. A flow path is defined through the valve only when the ball is disposed in an open position. In one embodiment, when the ball is disposed in a closed position the upstream seat may intermittently disengage from the ball to relieve hydrostatic expansion of a liquid within the ball resulting an increased pressure that is greater than a pressure within a body cavity of the valve outside the ball. In another embodiment, a distance between the upstream and downstream seats is greater than an outer diameter of the ball and the ball engages only one of the upstream and downstream seats when disposed in the closed position and a pressure differential is defined between the upstream and downstream seats. The upstream and downstream seats may each include a partially spherical sealing surface that may have a crenulate configuration.Type: ApplicationFiled: November 13, 2014Publication date: May 14, 2015Inventor: Charles C. Hansen, III

Patent number: 9027906Abstract: A filler assembly is mounted in an axial hole of a cap of a valve. The filler assembly includes at least one first filler and at least one second filler stacked in a longitudinal direction. A valve rod received in the axial hole extends through the at least one first filler and the at least one second filler. At least one of two mutually abutting faces respectively of the at least one first filler and the at least one second filler is at a non-parallel angle to a radial direction perpendicular to the longitudinal direction. If one of the at least one first filler and the at least one second filler is subjected to a pressing force in the longitudinal direction, at least one of the at least one first filler and the at least one second filler is moved in the radial direction to press against the valve rod.Type: GrantFiled: March 11, 2013Date of Patent: May 12, 2015Inventor: Wan-Rong Kung

Patent number: 9010725Abstract: A valve includes a stem seal assembly that prevent fluid flow in a first direction and vents in a second direction opposite the first direction. The assembly includes a packing assembly positioned within a valve stem opening of a valve body of the valve to seal a valve stem to the valve body. The packing assembly includes a first seal and a second seal preventing passage of fluid from a body cavity of the valve body to an exterior of the valve body along the valve stem while venting fluid from an exterior of the valve body to the body cavity along the valve stem. The packing assembly isolates the first seal and the second seal so that a load applied to the first seal ring is not transferred to the second seal ring.Type: GrantFiled: December 21, 2011Date of Patent: April 21, 2015Assignee: Vetco Gray Inc.Inventor: Rick C. Hunter

Publication number: 20150102247Abstract: A stem packing assembly including a first annular member defining a central axis, a second annular member defining a central axis coaxial with the central axis of the first annular member, and an annular energizing member defining a central axis coaxial with the central axis of the first annular member. In an embodiment, the stem packing assembly can have a leakage rate according to ISO 15848-1 of less than 1×10?4 mgs?1m?1 for at least 500 cycles at 160° C., and less than 1×10?4 mgs?1m?1 for at least 500 cycles at ?46° C. In another embodiment, the first annular member can include a PAEK, the second annular member can include a PTFE, and the annular energizing member at least partially includes a PTFE.Type: ApplicationFiled: September 30, 2014Publication date: April 16, 2015Inventors: Mathilde Leboeuf, Jan Kustermans, Rojendra Singh, Christophe Valdenaire, Filip Rousseau, Herman M.

Publication number: 20150090916Abstract: A ball valve including a valve body that includes a first body member and a second body member. The valve body defines a valve axis and a fluid flow path. A ball element has a port and a ball stem, and is rotatable about a ball stem axis between an open position providing fluid flow through the fluid flow path and a closed position inhibiting flow through the fluid flow path. A body seal is located between the first body member and the second body member and defines a thickness that decreases as the body seal extends away from the valve axis. A stem seal defines a substantially frusto-conical shape and is arranged in the valve body. The ball stem extends through the stem seal to form a seal between the ball stem and the stem seal and between the stem seal and the valve body.Type: ApplicationFiled: September 30, 2014Publication date: April 2, 2015Inventor: Peter Zollinger
