<p>Electro-pneumatic valve has a housing (1) containing a electrical coil (3) with an iron core (4). A plate anchor (5) is moved backwards via a flat spring (13) to electromagnetically activate a valve closing element (6). The latter is moved along its stroke and forms a tight fit with the valve seat (7, 8) in order to ensure a reliable seal formation. Both valve seat and closing element are made of hard material to ensure an effective seal.</p> |
