Abstract: The present invention relates to a driving apparatus and a valve including the same. The driving apparatus senses a pressure of a fluid medium and generating a driving force, and includes: a drive shaft, a sensing device, a limiting device, a support body, and a protruding member. The limiting device is provided with a groove, and the protruding member is engaged in the groove. The limiting device can automatically limit the rotation of the drive shaft, to avoid damaging to the sensing device, thereby facilitating maintenance and installation of the valve.

Abstract: A driving apparatus and a valve including the same. The driving apparatus senses a pressure of a fluid medium and generates a driving force. The driving apparatus includes: a drive shaft, a sensing device, a limiting device, a support body, and a protruding member. The limiting device includes a groove, and the protruding member is engaged in the groove. The limiting device can thus automatically limit the rotation of the drive shaft, so as to avoid damaging the sensing device, thereby facilitating maintenance and installation of the valve.
