Product Description
SBB DBB Ball Valves (Double block & bleed)
Single 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 SBB 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.
Single 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.
