IV6F, IV6T Series Ball Valve

Ball Valve Series IV6F, IV6T

Class 600, Regular/Full Port, Flanged/Butt weld Ends, Floating Design/Trunion Mounted Design

These High Performance Ball valves are available in Class 600 for Floating as well as Trunion Design.

A floating ball design offers efficient sealing with simple construction. As the name indicates, the ball has some freedom to move along the axis of the pipeline, which offers efficient downstream sealing. When line pressure is applied to the closed ball, it moves slightly (or floats) downstream to maintain contact with the downstream seat where primary sealing occurs. A quarter turn motion from full open to full close ensures quick open-close action, an inherent advantage for automatic remote control application. Floating ball valve offers effective bi-directional sealing.


Trunion mounted design offers precise locational accuracy for the ball within the upstream and downstream seat, which ensures leak tight sealing with lower operative torques. The sealing takes place by allowing the seats to move towards the ball. This design ball valves can hold very high pressures.
