TRUNNION MOUNTED TOP-ENTRY BALL VALVES

1 piece bolted bonnet design.

The ball of trunnion mounted configuration is supported by parts fixed 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.

PERAR Trunnion Mounted Top-Entry Ball Valves allow full in-line maintenance.

For this reason these valves can be welded to the pipeline without precluding possible repairing.

They are manufactured in a wide range of sizes and pressure classes typically with cast body.

Suitable for: FPSO, LNG Terminal, Offshore, Onshore, Pipeline Transportation, Power and renewvables, Refinery and petrochemical, Water desalination
