In oil & gas, LNG, petrochemical, and pipeline systems, valve isolation safety is a key factor affecting equipment reliability. Although standard ball valves provide excellent shut-off performance, DBB Ball Valves (Double Block and Bleed Ball Valves) offer higher safety levels through double isolation and pressure release functions.

Discover the benefits of J-VALVES trunnion mounted ball valves with two bleed ports. Designed for demanding oil & gas, natural gas, petrochemical and pipeline applications, these valves support cavity pressure relief, sealing verification and safer maintenance operations.

As a professional valve manufacturer, J-VALVES specializes in the design and manufacturing of high-performance Fully Welded Ball Valves for oil & gas pipelines, natural gas transmission systems, LNG facilities, and industrial applications.

Discover how J-VALVES manufactures and supplies certified trunnion mounted ball valves for oil and gas, petrochemical and energy projects through precision machining, quality control and customized engineering.

Designed according to API 6D requirements, a high-quality API 6D DBB Ball Valve must meet strict standards related to valve structure, pressure testing, sealing performance, and pipeline installation requirements. These design requirements ensure that the valve can provide safe isolation under high-pressure and demanding operating conditions.
