Control mechanism for butterfly valves, or other shutter, characterized in that it comprises in combination: a maneuvering device, adapted to request the shutter of the valve in the closing direction, and an automatic locking and tripping device comprising a holding latch of the maneuvering device in a position for which the valve is open, a mass intended for the kinetic energy due to its falling from an unstable equilibrium position to separate said bolt, and a moving body sensitive to speed of fluid through the valve body to cause the mass to pass through this unstable equilibrium position, since this velocity reaches a predetermined value.
