2/ 3 pieces side entry bolted body design.
The ball of trunnion mounted configuration is supported by bearing plates hold by the end adaptors. In such a way the pressure loads are transferred to the valve body granting a smooth rotation of the ball with low torque levels and reduced seat seal wear.
PERAR Trunnion Mounted Bolted Body Side-Entry Ball Valves represent the basic design standard.
They are manufactured in a wide range of sizes and pressure classes typically from forgings.
