Trunnion Ball

Trunnion-mounted ball with top and bottom anchoring absorbs line-pressure thrust, minimizing friction between ball and seats. This keeps operating torque low at full rated pressure.

Anti-Blow-Out Stem Design

Blow-out-proof stem prevents ejection under pressure, fully compliant with API 6D.

Antistatic Device

Built-in antistatic feature ensures electrical continuity across all metallic components.

Fire Safe

Standard fire-safe design, certified to API 6FA and API 607.

Mounting Flange

ISO 5211-compliant mounting flange for actuator installation.

Applications of Floating Top Entry Ball Valve
