OCV offers stock delivery on two piece and three piece trunnion mounted ball valves by DAFRAM SpA Italy. DAFRAM's trunnion mounted ball valves have independent floating inconel spring loaded seat rings that are always in contact with the ball to provide an effective seal at low differential pressures. At higher differential pressures the upstream seat ring becomes pressure energized against the ball to form a tight seal, while the downstream seat remains spring loaded. Trunnion mounted ball valves are available in most alloys cast or forged and can be used in double block and bleed applications.
