Patent number: 11796074Abstract: Multiport valve with outlets transverse to the inlet useful as a coker switch valve. A sealed lower sleeve assembly provides semi-trunnion ball support. An upper part of the outlet seat recesses is formed in the bonnet, and a lower part in the valve body, which together bias a resilient member to load the seats, independently of end connections. Before bonnet assembly, when the ball is rotated to face a body outlet, there is sufficient space in the seat recesses to insert the seat, slide the seat onto the ball, and then insert the resilient member. When all the seats and resilient members are in place, engagement of the bonnet biases the upper part of the resilient members to load the seat. In valve operation, an enlarged ball outlet bore can straddle two outlet ports and maintain process media flow during switching. Also, methods of assembling, operating, and servicing the valve.Type: GrantFiled: September 11, 2021Date of Patent: October 24, 2023Assignee: Mogas Industries, Inc.Inventors: Alfred Lewis Anderson, Asmaa Sadek Kassab, Phillip M.

Patent number: 11224903Abstract: A ball valve has a purge fluid inlet passage into a cavity between a valve body and a flow control element, and has a purge fluid drain. The inlet passage is oriented at an angle relative to a normal line to the spherical ball surface at the location of the inlet passage, to promote vorticial flow of the purge fluid. A method introduces a purge fluid into a ball valve body cavity; removes the purge fluid from an outlet drain; and induces a vortex in a flow path of the purge fluid through the body cavity. The method can flush debris from the body cavity between operating cycles of the ball valve by at least temporarily opening the inlet and outlet before and/or after operation of the valve.Type: GrantFiled: May 6, 2020Date of Patent: January 18, 2022Assignee: Mogas Industries, Inc.Inventors: Gifford Zach Decker, Asmaa Sadek Kassab, Anthony Neal Hodge, Robert D. Dibbern, Jr.

Patent number: 11174963Abstract: An operating system for switching a coker switch valve to drum A, drum B, and bypass. The system has a shear pin linkage between the actuator and the valve stem and a position indicator independent of the actuator, to maintain functionality in the event of shear pin failure; and/or lockout functionality to prevent an inadvertent switch to bypass when switching between drum A and drum B and to lock down bypass mode to prevent an inadvertent switch from bypass to an open drum.Type: GrantFiled: May 17, 2019Date of Patent: November 16, 2021Assignee: Mogas Industries, Inc.Inventors: Alfred Lewis Anderson, Asmaa Sadek Kassab, Phillip M.
