Frequently Asked Questions

Q What is a Double-Block-and-Bleed (DBB) trunnion ball valve, and why is it important?

A Double-Block-and-Bleed (DBB) trunnion ball valve features two independent seating surfaces that simultaneously block flow from both sides while allowing the cavity between them to be vented or bled. This design is critical for complete isolation and safe depressurization.

Q What pressure and temperature ratings does the trunnion ball valve support?

The valve is engineered to handle pressures up to Class 2500 / 6000 PSI and a wide temperature range from -196℃ to 450℃, depending on the selected body material.

Q What actuation options are available for this trunnion ball valve?

The valve supports multiple actuation methods including manual handwheel, worm gear, electric actuator, and pneumatic actuator, with optional ISO 5211 direct mounting pads.

Q What materials are available for the valve body?

A wide range of forged materials are available, including A694F52, A694F60, A182F316, A182 F51, Inconel 625, Incoloy 800, and Hastelloy C, selected for high resistance to corrosion.

Q Is this valve compliant with fire-safe and anti-static standards?

Yes. It is designed to comply with API 607 and API 6FA fire-safe testing standards and incorporates anti-static design and a Blow-Out Proof Stem for emergency safety.

Q What industries commonly use trunnion mounted forged ball valves?

These valves are widely used in Oil & Gas, Chemical & Petrochemical, Power Generation, Offshore & Deepwater platforms, and Water Treatment industries for critical process control.
