The seal can also include a second seal member including an annular ring configured to engage a distal end of the hub portion and create a sealing engagement between the hub portion and the annular ring when a compressive force is applied to the first and the second seal members.Type: GrantFiled: June 7, 2010Date of Patent: January 8, 2013Assignees: Saint-Gobain Performance Plastics Corporation, Saint-Gobain Performance Plastics FranceInventors: Yves Stefani, Roland Lucotte

Patent number: 8348235Abstract: A triple offset butterfly valve includes a valve body defining a valve orifice and a valve member rotatably mounted in the valve orifice. The valve member includes a disc element detachably mounted to a mounting plate; the valve member being mounted to a rotatable axle which extends between the disc element and mounting plane thereof. The valve body has an annular valve seat against which the disc element of the valve member seals when the valve is closed. In use, when the valve components become worn, the disc element of the valve member can easily be removed as a complete unit and replaced. In this manner, the need for a removable seal on the valve member is avoided, which reduces the number of potential leak paths as compared to known butterfly valves.Type: GrantFiled: March 26, 2007Date of Patent: January 8, 2013Inventor: Bryan Higgs

Publication number: 20120319022Abstract: Flexible seals for process control valves are disclosed. An example disclosed seal includes a seal for use with a butterfly valve. The example seal includes a substantially flexible ring-shaped carrier configured to be moveably fixed within the butterfly valve and to surround a flow control aperture therein. The example seal includes a seal stiffener adjacent the substantially flexible ring-shaped carrier to increase the stiffness of the substantially flexible ring-shaped carrier in a first flow direction. The example seal includes a substantially rigid seal ring to engage an opposing surface.Type: ApplicationFiled: August 27, 2012Publication date: December 20, 2012Inventors: Wade Jonathon Helfer, David John Koester, Benjamin Uriah Good, Paul Russel Dalluge, Andrew John Olsen

Publication number: 20120273708Abstract: Disclosed is a butterfly valve capable of controlling a flow of a fluid according to a rotation of a disk. The butterfly valve includes a body provided with an inner space having two open ends; a disk unit having a disk rotatably installed at the inner space, and configured to selectively open and close the inner space according to a rotation of the disk; a first seat portion protruding from an outer circumferential surface of the disk; a second seat portion protruding from an inner circumferential surface of the body, and arranged to face the first seat portion; and a sealing unit mounted to the body, and formed to contact the first and second seat portions such that a gap between the outer circumferential surface of the disk and the inner circumferential surface of the body is sealed. Under this configuration, the butterfly valve may have an enhanced reliability under low and high temperatures and a high pressure.Type: ApplicationFiled: October 20, 2011Publication date: November 1, 2012Inventor: Man Young KIM

Publication number: 20120267557Abstract: A butterfly valve having a valve body is provided. The butterfly valve includes a valve disk assembly rotationally coupled to the valve body. The valve disk assembly has a disk member with a first surface disposed about a periphery having a first diameter and a second surface offset from the first surface. A seal ring is arranged adjacent the first surface, the seal ring having a first outer surface with a second diameter, wherein the second diameter is larger than the first diameter. A retainer is coupled to the second surface adjacent the seal ring opposite the first surface. The retainer has inner surface arranged to radially constraining the seal ring on the disk member.Type: ApplicationFiled: April 21, 2011Publication date: October 25, 2012Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: William T. Lockwood, Scott W. Simpson

Patent number: 8286938Abstract: Flexible seals for process control valves are disclosed. An example disclosed seal includes a seal for use with a butterfly valve. The example seal includes a substantially flexible ring-shaped carrier configured to be fixed within the butterfly valve and to surround a flow control aperture therein. Additionally, the seal includes a ring-shaped cartridge coupled to an inner diameter of the ring-shaped carrier. The cartridge includes a first portion and a second portion coupled to the first portion to define a circumferential opening to hold a seal ring.Type: GrantFiled: April 27, 2007Date of Patent: October 16, 2012Assignee: Fisher Controls International LLCInventors: Wade Jonathon Helfer, David John Koester, Benjamin Uriah Good, Paul Russell Dalluge, Andrew John Olson

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
