BEL Valves’ Through Conduit Expanding Gate Valve enables double block and bleed (DBB) functionality to be achieved within one single valve assembly, as opposed to the two conventional slab gates that would otherwise be required. The benefits include an overall cost, size and weight reduction in addition to an ability to configure the valve to seal in either the closed position (single expanding) or open and closed position (double expanding). Further options ensure a fit-for-purpose solution is delivered to suit application demands.
