  • Patent number: 9927259
    Abstract: A rotary position indicator is configured to integrate with an actuator, wherein the rotary position indicator includes a first shaft and a second shaft in a nested arrangement, wherein the first and second shafts are configured to transfer linear motion of an actuation component of the actuator into a first rotational motion and a gear box configured to couple to the actuator, wherein the gear box is configured to transfer the first rotational motion to a second rotational motion of a position shaft.
    Type: Grant

  • Patent number: 9909683
    Abstract: A gearbox assembly for an actuator is provided. The gearbox assembly includes a rack, a spur pinion, a bevel pinion, and a bevel gear. Vertical translation of the rack causes rotation of the spur pinion and bevel pinion around a horizontal axis. The rotation of the bevel pinion causes rotation of the bevel gear around a vertical axis. The gearbox assembly may be coupled to a movable member of a valve so that actuation of the gearbox assembly moves the movable member. Systems including the gearbox assembly and methods of operation are also disclosed.

  • Patent number: 9518666
    Abstract: Embodiments of the present disclosure are directed toward a bidirectional travel stop assembly including a first travel stop configured to block a first axial movement of an actuation element of a valve actuator, a second travel stop configured to block a second axial movement of the actuation element, and a travel stop bushing configured to block adjustment of the second travel stop and allow adjustment of the first travel stop when the travel stop bushing is disposed within the valve actuator in a first axial orientation, wherein the travel stop bushing is configured to enable adjustment of the second travel stop when the travel stop bushing is disposed within the valve actuator in a second axial orientation.
