<p>The valve has a blower (4) that detects leakage of a fluid downstream a movable valve (1) and associated to a chamber (C) and a bypass (5). The blower is integrated to the valve. The bypass has a core (51) engaged inside a solenoid (52) and is sensible to a field induced by the solenoid when it is supplied. A detection unit (6) detects a preset position of the core of the bypass and a stopper (54) that are inside the solenoid. A trigger or control signal is sent to the solenoid, for displacing the core inside the solenoid towards the top, when the core attains the preset position.</p> |
