Description

Integral DBB Ball Valve, that is an integral body ball valve, is a specially designed ball valve. It combines double isolation (Double Block) and bleed (Bleed) functions, and double isolates the medium through two independent sealing surfaces to ensure safe operation. At the same time, a bleed port is set between the two sealing surfaces to discharge the medium in the intermediate cavity, which is convenient for testing the sealing performance and further improves the safety and reliability of the valve.


This valve is widely used in fields such as petroleum, natural gas, chemical industry, and electric power that have extremely high requirements for safety and sealing performance. Its compact design integrates two valves and bleed functions into one, reducing installation space and weight, while providing high sealing performance and operational flexibility. It has a variety of materials, and can be selected from stainless steel, carbon steel or alloy steel according to working conditions, suitable for a variety of media and working conditions.
