ValvTechnologies’ Double Block-and-Bleed Valves

Evaluate this Device

Improve protection and isolate large equipment areas safely by specifying ValvTechnologies’ valves with double block-and- bleed capability. The proven-in-the-field ValvTechnologies “package approach” lowers installation costs – and saves time – compared to individual component assembly. A bi-directional upstream seat system, plus a bleed connection with a standard isolation valve, allows superior flexibility in use, as well as smooth, low-torque operation. Customers save on wear and tear, improve valve service life, and maximize effective in-line performance.

  • Extra safety with primary and secondary bleed ports, secondary bleed point in double-isolation models

  • Integral metal seat comes with secondary, back-up seat

  • Metal-to-metal sealing – HVOF RiTechⓇ hard coating hand-matte lapped to ball – delivers guaranteed Zero-leakage

  • Apply to any high-pressure and low-pressure NexTech® trunnion valves or ValvTechnologies’ cryogenic valve
