Patent number: 10907746Abstract: A valve including a control assembly that is configured to control fluid flow through the valve, The control assembly includes a driving element and a valve member. The driving element is rotatable about an axis between a first operating state in which the driving element maintains contact between the valve member and a valve seat and a second operating state in which the driving element does not maintain contact between the valve member and the valve seat. The valve member is rotatable about the axis independent of the driving element when the driving element is in the second operating state.Type: GrantFiled: June 21, 2019Date of Patent: February 2, 2021Assignee: EMERSON PROCESS MANAGEMENT REGULATOR TECHNOLOGIES, INC.Inventors: Juan M.
