Double Block and Bleed Ball Valve

Australian Valve is a prime Double Block and Bleed Ball Valve Manufacturer in Australia. We supply to Brisbane, Canberra, Darwin, Hobart, Melbourne, Perth and Sydney. A Double Block and Bleed (DBB) Ball Valve is a type of valve that is designed to provide two independent sealing points within the same valve body. This ensures that the fluid or gas being transported is isolated from the environment, as well as from the downstream piping. The two seals are typically made of metal or a thermoplastic material, and they prevent fluid or gas from leaking out of the valve. Additionally, a bleed valve is included in the design to allow for pressure testing or venting of the valve. The ball valve component of the DBB allows for easy and quick shut-off of flow in pipelines, making it an efficient option for applications where isolation and control of fluid flow is required.
