Frequently Asked Questions
What pressure and temperature ranges can this trunnion ball valve handle?
The trunnion-mounted forged ball valve supports pressures up to Class 2500 / 6000 PSI and operating temperatures ranging from -196℃ to 450℃, depending on the selected body material and sealing configuration.
What is the Double-Block-and-Bleed (DBB) function, and why is it important?
The Double-Block-and-Bleed (DBB) design allows two independent seating surfaces to block flow from both sides simultaneously while providing a bleed port to vent the trapped cavity. This is critical for isolation and maintenance safety in high-pressure oil, gas, and chemical pipelines.
What actuation options are available for this valve?
The valve supports multiple actuation types including manual hand lever, worm gear operator, electric actuator, and pneumatic actuator. It also features an optional ISO 5211 direct mounting pad for easy actuator compatibility and integration.
Which body materials are available, and are they suitable for corrosive environments?
A wide range of forged body materials is available, including A694F52, A694F60, A694F65, A182F316, A182F347, 17-4PH, Inconel 625, Incoloy 800, and Hastelloy C, among others. These materials are selected for their resistance to corrosion, sulfide stress cracking, and harsh industrial conditions.
Is this valve certified for fire-safe and anti-static applications?
Yes. The valve complies with API 607 and API 6FA fire-safe standards and incorporates an anti-static design and blow-out proof stem, making it fully suitable for flammable media and fire-risk environments.
What industries and applications is this trunnion ball valve designed for?
This valve is engineered for demanding applications across Oil & Gas, Chemical & Petrochemical, Power Generation, Offshore & Deepwater platforms, Aerospace & Military, Water Treatment, and Metallurgical industries, where reliable high-pressure isolation is critical.
