These High Performance Ball valves are
available in Class 900 to 2500 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. |
