Design

All-welded body structure of the ball low body weight,their idealbody can handle the ball higher pressure and bending moment,able towithstand the high internal and external pressures.Choose differentmaterlal combinations to ensure that the valve be reliable in corrosivesituations,such as acidic gases.

Replaceable Trunnion Seal

The trunnion seals on our ball valve can be replaced even when thepipeline is under maximum pressure.

The modular design enables us to provide various trunnion sealsystems to meet your specific requirements.
