Patent number: 8517333Abstract: A valve actuator includes an actuator housing, a piston, a linkage assembly, a magnet, and a Hall sensor. The actuator housing is adapted to receive pressurized fluid. The piston is movably mounted within actuator housing, and is configured to translate in a first direction and a second direction. The linkage assembly is rotationally coupled to the piston and is adapted to couple to a valve element. The linkage assembly is configured to rotate the valve element in a first rotational direction and a second rotational direction in response to piston movement in the first direction and the second direction, respectively. The magnet is mounted on the piston and is movable therewith, and the Hall sensor is mounted on the actuator housing and is responsive to movement of the magnet to supply a position signal.Type: GrantFiled: September 2, 2010Date of Patent: August 27, 2013Assignee: Honeywell International Inc.Inventors: Ara Briley, Craig Kolb, Ed Kesner, Joel LaBenz, David Pantier, Dave Tornquist, Maureen Sugai

Patent number: 8276880Abstract: Butterfly valve plate sealing assemblies are provided that include a sealing ring and a retention spacer disposed at least partially within a sealing ring groove formed about a periphery of a butterfly valve plate. The sealing ring includes a first portion, a second portion configured substantially perpendicular to the first portion, and a substantially L-shaped cross-section. The sealing ring is positioned at least partially within a groove opening and a groove body defining the sealing ring groove. The retention spacer is positioned at least partially within the groove opening and adjacent the first portion of the sealing ring. The retention spacer is configured to limit expansion of the sealing ring when under the influence of a pressurized fluid flow. The second portion of the sealing ring may be configured to optimize stiffness for a desired sealing ring tension.Type: GrantFiled: May 28, 2009Date of Patent: October 2, 2012Assignee: Honeywell International Inc.Inventors: Craig Kolb, David Pantier, Joel LaBenz, Scott Martin

Publication number: 20100301241Abstract: A valve assembly includes a valve body, a valve element, a valve actuator, a main connector port, and a dummy connector port. The main connector port is coupled to the valve body and is electrically coupled to the valve actuator. The main connector is also adapted to mechanically and electrically mate to an electrical harness. The dummy connector port is coupled to the valve body and is disposed proximate the main connector port. The dummy connector port is electrically isolated from the valve actuator and is adapted to at least mechanically mate to the electrical harness in a manner that is at least substantially identical to the manner in which the electrical connector mechanically mates to the main connector port.Type: ApplicationFiled: May 27, 2009Publication date: December 2, 2010Applicant: Honeywell International Inc.Inventors: Joel LaBenz, David Pantier, Scott Martin

Patent number: 7739915Abstract: A diaphragm is provided that includes a plurality of zonal portions that define reinforced and non-reinforced areas of the diaphragm. A first zonal portion extends from a marginal edge portion toward a central portion and is formed of a fabric material. A second zonal portion extends from the first zonal portion toward the central portion and is formed of an elastomer. A third zonal portion defines the central portion and is formed of a fabric material. The combination of reinforced and non-reinforced portions provides for a decrease in the radial tension (spring rate) of the diaphragm and helps prevent undesired changes to the flow control valve flow setpoint.Type: GrantFiled: February 19, 2008Date of Patent: June 22, 2010Assignee: Honeywell International Inc.Inventors: David Pantier, Todd Garrod, John Vasquez, Paul Banta, Dave Tornquist
