<p>Coupled to the body (1) the valve has: a manometer (7), a solenoid valve (9), a presostate (10), a safety valve (11) and a firing element (12). The manometer (7), solenoid valve (9) and presostate (10) pressure entry conduits (22a, 22b and 22c) are related amongst themselves and connected with the inlet of the valve (13) by means of a single hole (23), with an anti-return valve (24) which, depending on its position, allows or not the passing of pressure towards said conduits (22a, 22b and 22c). The body (1) has an alleviation conduit (22d) that connects the manometer (7) pressure entry conduit (22a) with the exterior and, in the top chamber (15) a seal (26) to prove the activation of the valve. <IMAGE></p> |
