DOUBLE BLOCK AND BLEED BALL VALVE
ARAN Double block and bleed Ball Valve require two isolation in one line and a bleed function. It is applied to control the flow between the two 'ball valves' cavity in order to block the downstream pipeline in a safety way. The double block is playing the role of venting the pressure safety during maintenance by a valve stead of two bolted valves.
