<p> Provided is a high-pressure automatic NC diaphragm valve in which a valve seat is constantly under a large load because of a high-pressure force biasing a valve body, wherein the valve can be stored while the performance of the valve is maintained until the valve is used, and the valve can be stored for a long period of time. A diaphragm valve, in which a diaphragm is pushed open and closed by a piston mechanism inside an actuator provided in a body, is configured such that a stationary-side locking part is provided to a casing of the actuator, a movable-side locking part is provided in an appropriate position on the piston mechanism, and when the piston mechanism is moved to an upper releasing side, the locked positions of the stationary-side locking part and the movable-side locking part coincide, and the stationary-side locking part and the movable-side locking part are locked by a holding member inserted from the outside of the casing.</p> |
