BS 5351 DBB Trunnion Ball Valve, DN100, PN100, Fully Welded

This Double Block and Bleed (DBB) trunnion ball valve is designed in accordance with BS 5351 standards to ensure safe isolation and reliable performance in high-pressure pipeline systems. Featuring a fully welded construction, the valve provides superior strength and eliminates potential external leakage paths. The ASTM A182 F316 stainless steel body and trim offer excellent corrosion resistance and durability in demanding environments. With a DN100 size and PN100 pressure rating, the valve is suitable for severe service conditions. The double ball design, RF flanged ends, and lever operation ensure tight sealing and smooth, efficient control. As a leading DBB trunnion ball valve provider from China, we deliver high-quality, engineered valve solutions for global industries.
