Features & Benefits
True DBB in One Body
Two independent balls with body cavity bleed provide true double block and bleed isolation in a single compact forging.
Integral Needle Bleed
SS316 needle valve integrated into monoblock body eliminates threaded connections and potential leak paths between valves.
Compact Monoblock Design
Forged single-body construction replaces two ball valves, three flanges, and multiple gaskets, reducing weight and footprint by 70%.
Fire-Safe API 607
Secondary metal-to-metal seat contact and graphite packing maintain isolation during external fire per API 607 6th Edition.
Anti-Static Design
Spring-loaded electrical continuity between balls, stems, and body prevents static charge accumulation in hydrocarbon service.
