Patent number: 10989175Abstract: The present invention utilizes operation of a valve actuator to generate electrical power. A portion of the mechanical energy generated by operation of a valve actuator is converted to electrical energy. The mechanical energy may be converted to electrical energy at the same time as the valve actuator is operating or the mechanical energy may be stored for later conversion. A valve actuator may be operated manually, electrically, pneumatically, or hydraulically. Generated electrical energy may also be stored.Type: GrantFiled: February 27, 2018Date of Patent: April 27, 2021Assignee: Flowserve Management CompanyInventors: William T. Dolenti, Daniel J. Morris, Daniel Carlson, Byron A. Fleury, David R. Simons

Patent number: 10962141Abstract: An actuator position control system includes an electronic controller and encoder that control and monitor an actuator's position between its position limits, while mechanically actuated limit switches prevent attempts to exceed the actuator's position limits, even if there is a loss of calibration, software error, or electronic controller failure. When actuated, the limit switches provide position calibrating information to the electronic controller. Embodiments can control linear and/or rotary actuators. The encoder can include intermeshed gears and magnetic Hall-effect position sensors. A mechanically driven position indicator can visually indicate the actuator's position. An electromechanical control system can be included that can transition the actuator between its limits even in the event of electronic controller failure. Embodiments can alert a user if the electronic controller fails.Type: GrantFiled: July 13, 2017Date of Patent: March 30, 2021Assignee: Flowserve Management CompanyInventors: Daniel J. Morris, William C. Hooss, Mark D. Ollander, Daniel E. Carlson

Patent number: 8714024Abstract: A device for axial load measurement on a mechanical control device having a rotating shaft may be used to derive a torque measurement. A mechanical control device may comprise a valve actuator for fluid flow control devices. The load measurement device may include a beam operatively connected to a rotatable shaft and configured to deform under axial displacement of the shaft. A sensor may be coupled with the at least one beam and configured to produce an output signal related to the axial displacement of the shaft. The beam may be retained between two bearings on the rotatable shaft at a first end, and fixed to a housing of the mechanical control device at a second end. The first end of the beam may displace axially with the rotatable shaft. The beam may comprise a discrete segment of a uniform width and thickness.Type: GrantFiled: June 30, 2011Date of Patent: May 6, 2014Assignee: Flowserve Management CompanyInventors: Byron A.
