ELECTRICALLY CONTROLLED ACTUATING DEVICE INCORPORATING A THERMOSTATIC FUNCTION, AND VALVE

摘要

The actuating device comprises: · a fixed portion forming a frame comprising an inlet intended to receive a fluid, a main outlet and a sampling outlet and return means for exerting a mechanical force on a movable portion; · a movable portion comprising a shutter moving between an open position and a closed position; · a thermostatic device comprising a conical turning disc, the turning of the disc above a known critical temperature driving the shutter to the closed position of same; · a control device allowing a holding force for holding the shutter to be generated, the control device being able to be controlled in such a way that below the critical temperature, the opening or closing of the valve results from the balance between the holding force and the mechanical force.
