The DBB Series high-pressure double block and bleed valves are designed for reliable isolation in compact and demanding applications. Rated up to 10,000 psi (690 bar), these valves feature a Ball/Needle/Ball configuration with two soft-seated ball valves for primary and secondary isolation, and a metal-to-metal seated needle valve for safe venting. Manufactured from NACE-compliant bar stock with anti-blowout stems, the DBB range is ideal for pressure take-offs and installations where space is limited.
