Product Description

NAILOK Stainless Steel Alloy 625 Double Block and Bleed DBB Valve Process Monoflange

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.
