Operating principle
Valve Closed position: When the valve is in the non-actuated position (OFF position), medium A and medium B are reliably separated. The leakage cavity open towards the atmosphere in this case. After switching , the medium in the valve disk leakage areas can drain by gravity. The connection is also served as a leakage indicator.
Valve Open position; When the valve opens, the leakage paths towards the atmosphere are colsed.
Cleaning of the leakage cavity: The leakage paths can be cleaned/flushed if necessary. For this purpose, the two cleaning connections can be integrated into the CIP circuit. It can be flushed when the valve is closed. The cleaning pressure in the suppl line should be slightly lower than the inside process pressure(hygienic aspects)
