Product Description
Nai-Lok Dbb SBB Ball Valves Manufacturer F316 Body Double Block and Bleed Instrument Manifolds Class 2500 for Oil and Gas ASME B16.5 150LB DBB Ball Valves
Product Description
Ball valves are used to cut off or connect the medium in the pipeline, as well as to regulate and control the fluid. As a
professional manufacturer of customized valves, we can provide you with all kinds of floating and trunnion mounted ball valves.
Ball valves mainly feature compact structure and reliable sealing. The sealing surface and spherical surface are often closed,
which means it's not easy to be eroded by medium and easy to operate and maintain. NAI LOK is a professional ball valve supplier
and valve manufacturing company that has different types of ball valves for sale. We are good at making cast hand operated valve
and forged ball valve with various special alloys, which are suitable for general working media such as water, solvent, acid and
natural gas, as well as suitable for bad working.
Nickel valve applications: high concentration of alkali and reducing media
Monel applications: sulfite, phosphoric acid, thermal soda, high temperature halogen and reductive media
Hastelloy applications: hydrochloric acid, sulfuric acid, formic acid, phosphoric acid, organic acid, etc
Double Block and DBB Ball Valve has Dual ball structure which evolved to replace and add the process of bolting together individual valves to make the valves in one body. it saved a lot of space and material, it is the development tendency of the valve in the future.

DBB Ball Valves (Double block & bleed)
Double block & bleed ball valves are mainly suitable for the instrumentation but is also required as an alternative to the in-line installation of two valves.
Thanks to a DBB ball valve, it is possible to have the same result reducing costs, overall dimensions and the ability to bleed off the plant, by controlling a potential leakage of the plant.
Double block & bleed valves DBB are recommended for any pressure class and ensure long-lasting seal.
They can be supplied both in the Trunnion and in the Floating version.
Main applications in the petrochemical field:
- Cryogenic service.
- Low temperature.
- Ambient temperature.
- High temperature.
- Corrosive fluids.
- High pressures.
- Samplings from line.
- Fluids injection.
