Key Specifications / Features
Designed to API 6D and BS 5351 standards, this DBB trunnion ball valve features a robust ASTM A105N forged steel body with durable F304 stainless steel trim for excellent strength and corrosion resistance. With a 2-inch size, Class 1500 LB (PN250) pressure rating, and full welded construction, it ensures maximum structural integrity and zero leakage performance in high-pressure applications. The gear-operated mechanism enables smooth, precise operation, while RTJ flanged ends provide secure, high-integrity sealing for critical service conditions. Ideal for oil, gas, and petrochemical systems, it delivers long service life and reliable shutoff. As a leading DBB trunnion ball valve supplier in China, we provide consistent quality and global project support.
