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.
