摘要
<p>The double safety valve has two coaxial closing components (33, 34). These and a magnet (32) are mounted on a common valve stem (15). The closing component (34) nearer the outlet and the magnet are coupled to the movement of the stem and the closing component acts as a double-seat valve which compensates for tolerances.</p>
