Valvitalia is the only valve manufacturer in the world that makes a TRIPLE OFFSET “NON CONTACT” BALL VALVE. We call it Konosphera. The Konosphera presents considerable advantages: it is a quarter turn and a ”true” trunnion mounted ball valve and it means that it is easy and quick to operate with a standard quarter turn actuator, requiring far less space than a linear actuator. Moreover the valve has no weak points and no cams that can be damaged. Konosphera represents the state of the art in metal seated valve technology.
