Patent number: 10337633Abstract: A relief valve including a body defining an inlet. A valve closure element is disposed at least partially within the body and arranged to allow selective flow through the relief valve in response to a predetermined pressure. An outlet housing that is separate from and coupled to the inlet housing is rotatable with respect to the inlet housing. The outlet housing defines an outlet that is in selective communication with the inlet.Type: GrantFiled: September 3, 2014Date of Patent: July 2, 2019Assignee: Emerson Vulcan Holding LLCInventors: John R. Grenaway, Mark K. Hamm, John B. Miller, William C. Osteen

Publication number: 20140102559Abstract: A high flow pressure regulator valve is disclosed having an integral pilot valve. The disclosed valve includes a pressure regulating portion including inlet and outlet ports, a valve seat, valve disc and a spring for biasing the valve disc into engagement with the valve seat. The valve also includes a pilot valve portion positioned on the flow regulating portion. The pilot valve portion includes a pilot spring, a diaphragm and a pusher post. One end of the pusher post is positioned toward the diaphragm and a second end is disposed within an annulus region. The valve further includes a pressure path that enables selective fluid communication between the outlet port, the annulus, an inner chamber region disposed beneath the diaphragm, and an intermediate chamber disposed above the valve disc.Type: ApplicationFiled: December 23, 2013Publication date: April 17, 2014Inventors: John R.

Patent number: 8517043Abstract: An adjustable economizer valve is disclosed that does not overlap the pressure build function, which allows a single valve to be used for both high and low gas use applications. The valve will economize well and reduces system pressure when needed in low use applications. The valve also provides maximum pressure build capacity when needed in high gas use applications. The valve seals off the pressure build outlet from the economizer connection with a seal around a pusher post disposed in the valve body. The pusher post has an internal flow path that is sealed by a floating device that can create a seal from diaphragm pressure and can open when diaphragm pressure is removed. In exemplary, non-limiting, embodiments, the floating device can be a ball or a disc plate.Type: GrantFiled: November 9, 2010Date of Patent: August 27, 2013Assignee: Pentair Valves & Controls US LPInventor: Mark K Hamm

Patent number: 8066026Abstract: A diaphragm controlled bypass valve includes a diaphragm valve portion and a needle valve portion. The diaphragm valve portion regulates pressurized gas supplied from a pump to determine whether or not to open or close a needle valve. The needle valve portion includes an inlet port, an outlet port and a flow pathway defined between the inlet and outlet ports. A needle pin is disposed within the flow pathway and is coupled to a diaphragm positioned within the diaphragm valve portion. When the diaphragm is displaced in response to changes in pressure, the needle valve pin is likewise displaced which opens and closes the flow pathway.Type: GrantFiled: May 8, 2008Date of Patent: November 29, 2011Assignee: Tyco Values & Controls LPInventors: John R. Grenaway, Mark K. Hamm, William Clinton Osteen

Publication number: 20110061742Abstract: A cryogenic liquid cylinder pressure control manifold is disclosed. The manifold includes, in a unitary arrangement, a pressure build regulator, a pressure build inlet fitting, a pressure build regulator, NPT adapter fitting, a check valve, and a cylinder pressure gauge. The disclosed manifold eliminates various threaded connections associated with prior devices, thus providing a more reliable device having less likelihood to leak in service. The disclosed manifold also reduces labor costs associated with assembling prior systems which are composed of a plurality of different individual components. In one embodiment, the disclosed manifold is employed as a cryogenic CO2 manifold for use in the beverage industry.Type: ApplicationFiled: September 10, 2010Publication date: March 17, 2011Applicant: Tyco Valves & Controls LPInventors: William Clinton Osteen, Mark K.
