The "Double Block and Bleed Isolation Philosophy," used in Valbart's Double Block and Bleed Valve, DBBV, 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.
