  • Valve automation mechanism and valve automation method
    Publication number: 20240019041
    Abstract: A valve automation mechanism that can be easily attached to a large manual valve, can motorize the valve, and is sufficiently downsized so as to be placeable in a narrow installation space is provided. A valve automation mechanism includes a gear attaching mechanism, a support mechanism, a drive mechanism, and a control part. Further, the gear attaching mechanism has a handle rotating gear. Further, the drive mechanism rotates the handle rotating gear and generates a driving force for motorizing the rotation of a handle.

  • Actuator
    Patent number: 11473695
    Abstract: An actuator that is capable of securing sufficient quietness when driven, that is small in size, that has excellent power transmission performance because of a high reduction ratio, and that is capable of performing highly accurate control. The actuator functions as a valve actuator that opens or closes a valve. The actuator includes a drive transmission gear, a motor, a friction drive speed reducer, a wave gear reducer, and an absolute encoder.
