DBB Ball valves suitable for those service areas of Gas Treatment, LNG, Oil and Gas, Power Generation, Power Generation, Chemical Processing, Gas Production, LNG, Offshore, Oil Production, Petrochemical Processing, Petroleum Production and Refining,

DBB Valves requires two in-line isolation valves and a bleed valve. These elements are used to drain or vent trapped fluid between the two closure elements in order to safely isolate the downstream pipe. This feature is achieved with one single valve containing a bleed port between the two valves.
