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.
