Trunnion Valve Ball has additional mechanical anchoring at the top and bottom. The Trunnion style ball prevents ball blowout and contributes to low operating torque. It is suitable for large and high pressure ball valves. This design of trunnion valve ball provides automatic relief of cavity overpressure. These balls are available with soft as well as metal seats designed for either high temperature or cryogenic service.
