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.

Power generation for valve actuators

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.

A roller device, including a first tube having a first diameter, and a through-bore having a second diameter smaller than the first diameter, the through-bore extending through and concentric with the first tube, a first rod having a third diameter smaller than the second diameter, a first end, and a second end, where the second end of the first rod is operatively arranged to telescopingly engage with the through-bore of the first tube, a second rod having a fourth diameter equal to the third diameter, a first end and a second end, where the first end of the second rod is operatively arranged to telescopingly engage with the through-bore of the first tube, at least one roller arranged to rotate about the first tube, and a first handle fixedly secured to the first end of the first rod.

A valve actuator including an electric motor is disclosed that includes a solid-state motor controller capable of operating a motor at variable speeds and a gear set that provides inherent braking. The speed and torque of the valve actuator may be selected. The speed and torque experienced by a valve may be varied over the length of a valve stroke. The valve actuator may include logic sufficient to act as a process controller.

Variable-speed actuator

A novel method for diagnosing problems with a valve actuator or other rotary equipment. Frequency analysis is performed upon speed, position, torque, thrust, or vibration data. Speed or position data may be provided by a rotary encoder.

Rotary encoder frequency analysis

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.

Load measurement method and device

A torque limiting device with an override mechanism coupled to a valve assembly capable of limiting the torque applied to the valve assembly and selectively being overridden to permit the application of excessive torque to the valve assembly. Tattletale devices capable of indicating when an override mechanism has been activated can also be integrated with the torque limiting device.

Handwheel torque limitor

Torque indicator markings incorporated with handwheel devices connected to actuators or valve assemblies provide visual indication of the amount of torque being applied to an actuator or valve assembly by the handwheel device. Tattletale torque indicators incorporated with a handwheel device further provide a persistent indication of the maximum amount of torque applied to an actuator or valve assembly connected to the handwheel device.
