PNEUMATIC TYPE OPERATING MECHANISM, AND PNEUMATIC TYPE OPERATION VALVE

PROBLEM TO BE SOLVED: To provide a pneumatic type operating mechanism composable with different operating directions with respect to a valve element in a valve mechanism by simple work without requiring spare parts accompanying change of a circulation circuit. SOLUTION: The pneumatic type operating mechanism 2 is equipped with an operating means 20 internally provided with an operating member 200, an energizing means 30 for energizing the operating member, and a connecting means 40 for connecting the valve mechanism 1 carrying out circulation control of a fluid and the operating means. The energizing means is composed of a coil spring, and the connecting means is equipped with a cylindrical housing 410 inserted with a shaft body 400, a pair of screw members 412a, 412b rotatably attached to both ends of the housing and composed so they can be screwed in externally fit states onto either one of a cylindrical valve mechanism side connecting part 13 provided on the valve mechanism and a cylindrical actuator side connecting part 206 provided on a casing of the operating means, a first spring receiver 420 fixed to a one end side of a housing interior, and a second spring receiver 430 fixed to a one end side of the shaft body positioned in another end side of the housing.
