SELBSTTAETIG BETRIEBENE FLUESSIGKEITSKUPPLUNGSANORDNUNG VON UEBERFLUESSIGEM TYP.

摘要

The coupling section has an elongated body with a central flow passageway. An actuating member is provided for movement relative to the body between two extreme positions. Two valve elements are arranged to operate in the passageway between open and closed positions corresponding to the position of the actuator. An actuator mechansim allows selective movement of the valve elements between their open and closed positions. In one extreme position of the actuating member the valve elements redundantly close the flow passageway.
