<p>The connecting union consists of two halves, on which plugging together the valve slide displaceable, by an external actuating sleeve, latches the locking sleeve against displacement into its free position, when the slide is in the valve open position. The slide moves, during its opening movement, a locking ball into its locking position and latches the locking sleeve in its free position. The arresting arrangement can be released by the connecting union half with the plug nipple. The locking ball can release the locking sleeve only on its deflection, which can be brought about only with valve slide displaced in its closed position. With the connection union halves, separated the locking sleeve is secured in its free position.</p> |
