Frequently Asked Questions
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 in high-pressure oil and gas, chemical, and offshore systems where complete isolation and safe depressurization are required to prevent leaks and ensure personnel safety.
What pressure and temperature ratings does the trunnion ball valve support?
The trunnion-mounted forged ball 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. This makes it suitable for cryogenic, ambient, and high-temperature process environments.
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. It also offers optional ISO 5211 direct mounting pads, locking devices, and stem extensions for flexible installation and automation compatibility across a variety of industrial systems.
What materials are available for the valve body?
A wide range of forged and alloy materials are available, including A694F52, A694F60, A694F65, A182F6A, A182F316, A182F347, 17-4PH, A182F44, A182 F51, A182 F53, Inconel 625, Incoloy 800, and Hastelloy C. These materials are selected for resistance to corrosion, sulfide stress cracking, and extreme industrial conditions.
Is this valve compliant with fire-safe and anti-static standards?
Yes. The trunnion ball valve is designed to comply with API 607 and API 6FA fire-safe testing standards, and incorporates anti-static design to prevent electrostatic buildup. The Blow-Out Proof Stem further ensures structural integrity under fire and emergency conditions, making it suitable for use in flammable and hazardous service environments.
What industries commonly use trunnion mounted forged ball valves?
Trunnion mounted forged ball valves are widely used across Oil & Gas (upstream, midstream, downstream), Chemical & Petrochemical, Power Generation, Offshore & Deepwater platforms, Aerospace & Military, Water Treatment, and Metallurgical industries. Their ability to handle high-pressure, high-temperature, and corrosive media makes them a trusted choice for critical process control applications worldwide.
