The preferred installation of a cyclone ball valve is in the vertical position. This will insure that gravity will seat the ball properly
each time. The pressure rating for Cyclone ball valves is 150 pounds per square inch. Cyclone ball valves incorporate a
standard sinking ball, which operates on gravity. Special floating balls are available for valves to be installed in different
positions than described above. The maximum recommended operating temperature for Cyclone ball check valves is 180°F.
