Double Block And Bleed Ball Valve

The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
