Patent number: 11668403Abstract: Technologies are described for devices and methods to seal a diaphragm to a body exterior seal periphery. The methods may comprise rotating a handwheel of a bonnet assembly to move a load plate to apply a compression force to a top portion of a transition pressure ring. The top portion of the transition pressure ring may have a circular cross section. A bottom portion of the transition pressure ring may include a bead that may project out from a bottom surface of the bottom portion and may have a congruent shape and size as the body exterior seal periphery. The body exterior seal periphery may not be congruent to the circular cross section of the top portion. The compression force may press the bead against a diaphragm assembly and the diaphragm against the body exterior seal periphery, to seal the diaphragm to the body exterior seal periphery.Type: GrantFiled: February 20, 2019Date of Patent: June 6, 2023Assignee: ITT Manufacturing Enterprises LLCInventor: Louis E.

Patent number: 11236833Abstract: Diaphragm valves include plastic diaphragm and reduced or no elastomer backing cushion, where peripheral or all sealing forces may be applied directly to the diaphragm of the valve assembly. The valve assemblies may include a pressure ring to apply sealing force to a surface of the diaphragm with a reduced size or no backing cushion allowing a two-fold or more increase in pressure capacity of the valve assembly. An elastomer or metallic spring placed above a center diaphragm boss may provide center-to-edge compliance for passage seal.Type: GrantFiled: June 26, 2020Date of Patent: February 1, 2022Assignee: ITT Manufacturing Enterprises LLCInventors: Louis E.

Patent number: 9709189Abstract: A valve, including a diaphragm valve, is provided featuring a cover in combination with at least one inner housing component. The cover may be configured with a biased-pin mounted therein. The at least one inner housing component may be configured with a hole or slot formed at a predetermined location where the biased-pin is at when the valve is calibrated to be at a final position. The cover may be configured to rotate and cause an axial translation between the cover and the at least one inner housing component so that the biased-pin engages the hole or slot when the valve is at the final position so as to stop any further axial and rotational movement.Type: GrantFiled: February 28, 2014Date of Patent: July 18, 2017Assignee: ITT MANUFACTURING ENTERPRISES LLCInventors: Louis E.

Patent number: 9322482Abstract: Apparatus, including a diaphragm valve, is provided featuring a valve body, a diaphragm, a pressure ring, and at least one elastomeric member. The valve body may include a circumferential flange. The diaphragm may include a circumferential gasket portion configured to be seated on the circumferential flange so as to form a joint between the valve body and the diaphragm. The pressure ring may include concentric fluctuations, and may be configured to apply a sealing force against the joint so that the concentric fluctuations prevent radial movement of the circumferential gasket portion and the circumferential flange. The elastomeric member may be configured to respond to a compressive force and provide a substantially constant sealing force, transmitted through the pressure ring, regardless of small variations in the thickness or material dimensions of the circumferential gasket portion caused by temperature fluctuation or material flow and age.Type: GrantFiled: July 20, 2012Date of Patent: April 26, 2016Assignee: ITT MANUFACTURING ENTERPRISES LLC.Inventors: Louis E. Matalon, Ronald G. Butler

Patent number: 9243718Abstract: A weir-type diaphragm valve includes a valve body having a spherically-shaped valve body sealing surface with a weir having a spherically-shaped weir sealing surface; and a diaphragm having a diaphragm sealing surface with a diaphragm weir sealing surface, the diaphragm responding to an applied force and providing sealing contact between the diaphragm weir sealing surface and the spherically-shaped weir sealing surface so as to stop the flow of fluid through a fluid flow channel of the valve body.Type: GrantFiled: August 27, 2012Date of Patent: January 26, 2016Assignee: ITT MANUFACTURING ENTERPRISES LLC.Inventors: Louis E. Matalon, Paul S. Gifford

Patent number: 9157534Abstract: A diaphragm valve features a valve body having a fluid flow channel with a weir portion to control the flow of fluid through the fluid flow channel; a diaphragm that responds to a closing or force to make sealing contact with the weir portion to interrupt said flow, or to release the sealing contact with the weir portion to allow the flow; a compressor configured to apply the closing or force in order to interrupt or allow the flow; and two studs configured to: couple the compressor and the diaphragm together, attach to the diaphragm to provide attachment points on the diaphragm on each side of the weir portion, and respond to the closing or opening force so the attachment points on both sides of the weir portion cause the diaphragm to make sealing contact with the weir portion or cause the sealing contact to be released.Type: GrantFiled: July 20, 2012Date of Patent: October 13, 2015Assignee: ITT MANUFACTURING ENTERPRISES LLC.Inventor: Louis E. Matalon

Patent number: 9046180Abstract: A weir-type diaphragm valve includes a valve body with a fluid channel and a weir with a weir sealing portion; and a diaphragm with diaphragm portions, including a diaphragm weir sealing portion at the weir that responds to one force and travel against the weir sealing portion to close the valve and stop fluid flow through the fluid channel, and responds to a second force and travel away from the weir sealing portion to open the valve and allow fluid through the fluid channel, a center flexing portion off the weir that experiences convex and concave flexing extremes when the valve is closed/opened, and an outer sealing portion fully constrained between components, one of which includes the valve body, when the valve is closed/opened. The diaphragm portions have different characteristics based on different material stresses associated with different functionality that each portion performs when the valve is closed/opened.Type: GrantFiled: August 30, 2012Date of Patent: June 2, 2015Inventor: Louis E.

Patent number: 9016307Abstract: A diaphragm valve has a valve body with a passage to be opened to allow fluid to pass through the valve body and to be closed to prevent fluid from passing through the valve body, and has a bonnet assembly with a pressure ring to load and unload a diaphragm based on a first spring constant to seal a peripheral portion of the diaphragm, and a compressor to close or open the passage of the valve body. The valve body and bonnet assembly have a connection that allows the valve body and bonnet assembly to be substantially fixed together with a second spring constant that is substantially higher than and independent from the first spring constant.Type: GrantFiled: July 20, 2012Date of Patent: April 28, 2015Assignee: ITT Manufacturing Enterprises LLC.Inventor: Louis E.
