Split Body Side Entry Ball Valves

STANDARD MODEL (EB)

VALVE DESCRIPTION 

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.

SMALL MODEL (EC)

VALVE DESCRIPTION 

The ball of trunnion mounted configuration is supported by external trunnions bolted to the body.
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.
