Which Valve is also known as DBB valves. This valve is a space-saving dual isolation solution that reduces the need for costly multi-valve systems ?

Double Block and Bleed Valves

Double block and Bleed can provide isolating for up stream and downstream directions.delivery time of DBB is comparatively less than conventional valves and Commercial part depends on material.

Instead of using two discrete valves to achieve tight isolation, DBB (Double Block and Bleed) valves combine the double isolation into a single valve with a drainage connection into the plug cavity that is added by drilling and tapping through the bottom of the valve body.
