<p>The electrovalve is operated by an electromagnet having winding (10), upper fixed core (8), lower moving core (9) and return spring (18). A cylindrical sleeve (11) supports these components and is watertight through "O" rings (14). The moving core (9) acts through an intermediate block (15). The intermediate block (15) has feet which bestride a fixed element (19) and touch the valve (5) on it's seating (4). The entry and exit to the valve are provided by channels (7,6,23,24) and manual operation is obtained by a rotating element (20). "O" rings (21,22) make the fixed element (19) and rotating element (20) watertight.</p> |
