DBB Trunnion Ball Valve, F55, 10 Inch, DN250, 600 LB, PN100

Key Specifications / Features

Model No. : 181302049

Engineered to API 6D and BS 5351 standards, this 10-inch (DN250) trunnion-mounted ball valve features a high-strength ASTM A182 F55 duplex stainless steel body for superior corrosion resistance and durability in demanding environments. The A105 + ENP trim enhances wear resistance and ensures reliable sealing performance under high pressure. Rated for Class 600 LB (PN100), the valve is designed for secure operation in critical pipeline systems. RF flanged ends provide leak-tight connections and easy installation, while gear operation enables smooth, controlled valve actuation. As a leading DBB trunnion ball valve factory from China, we deliver robust, high-performance solutions for industrial flow control.
