Abstract:
A device (10; 110; 210; 310) includes a support structure (12), on which there are mounted a plug (16), which is adapted to assume a plurality of operating positions including an opening position and a closing position, in which the plug is adapted to at least partially free and respectively obstruct a passage (14), which is meant for a fluid flow. A mechanism (18) is suited to move and hold the plug (16) between said operating positions. An opening actuator (20) and a closing actuator (22) are suited to separately act upon the mechanism (18), so that the mechanism (18) moves and holds the plug (16) between said operating positions, namely towards said opening position and towards said closing position, respectively, due to electric current supplied to the opening actuator (20) and to the closing actuator respectively.
