Product Details

The High-Temperature Double Block and Bleed Fixed Ball Valve with Trunnion Mounted Design is engineered for reliable performance in high-temperature, high-pressure systems. It features a metal-seated ball valve design, providing exceptional sealing capability in extreme environments, especially in applications involving particles or corrosive media.

The valve is equipped with a fixed ball structure, offering superior stability and ensuring that it maintains a tight seal even under fluctuating pressure. The heavy flanged connection is perfect for large-diameter, high-pressure pipelines, making it ideal for industries such as oil & gas, chemical processing, power generation, and more. This valve is also available in 3-piece ball valve configurations and can be customized with different materials and sizes to ensure optimal performance for various applications.

Frequently Asked Questions
What are the advantages of a Double Block and Bleed (DBB) design?
The DBB design allows for simultaneous blocking of both the upstream and downstream sides of the valve, providing a secondary seal. It also allows for the venting or bleeding of the cavity, ensuring maximum safety during maintenance.
How does the metal-seated design handle high temperatures?
Unlike soft-seated valves, metal-seated ball valves utilize high-strength alloys that do not degrade under extreme heat, making them perfect for thermal oil, steam, and high-temperature chemical processes.
Can this valve handle abrasive media or particles?
Yes, the trunnion-mounted fixed ball and metal seating are specifically designed to resist wear and tear from particles, ensuring a long service life in slurry or corrosive environments.
What industries typically use heavy flanged ball valves?
These valves are widely used in the Oil & Gas, Petrochemical, Power Plant, and Water Treatment industries where high-pressure integrity is critical.
Is the anti-static design a standard feature?
Yes, our high-temperature valves include anti-static and fire-safe designs to prevent electrical discharge and ensure safety in volatile or flammable environments.
Are custom sizes available for specific pipeline requirements?
Absolutely. We offer customization in terms of dimensions, pressure ratings, and material selection (such as stainless steel or carbon steel) to fit your specific application.
