ASTM A182 F51 DBB Ball Valve, API 6D, 12*10 IN, CL1500, RTJ

The ASTM A182 F51 Ball Valve Supplier offers high-quality double block and bleed ball valves designed to meet API 6D standards. These valves feature a duplex stainless steel body made from ASTM A182 F51, providing excellent corrosion resistance and durability. Available in a size combination of 12 inches by 10 inches (DN300 by DN250), they operate at a pressure rating of Class 1500 LB and PN250. The valves come with ring-type joint (RTJ) ends for secure and reliable connections.

Product Name: Double Block and Bleed (DBB) Ball Valve
Design Standard: API 6D

Double Block and Bleed (DBB) Valves are engineered for double isolation functionality, achieved by inserting two obturators within a single body. The valves feature a bleed/vent system positioned between the obturators (such as the body port and ball, gate, or needle valve), offering enhanced safety and reliability. This design enables the isolation of a pipeline section from both sides of the valve, ensuring secure shutoff and minimizing the risk of leaks, making it ideal for high-risk industries like oil and gas. The DBB ball valves help reduce the need for additional valves, optimizing both space and cost efficiency while maintaining strong security and operational safety.
