In high-pressure pipeline systems, valve reliability and sealing performance are critical for safe operation. The Trunnion Mounted Ball Valve has become a preferred solution for oil & gas, LNG, petrochemical, and industrial applications due to its stable structure, low operating torque, and long service life.

Step-by-step guide to select blue floating ball valves based on pipeline media, pressure & temperature range, body material, flange connection, manual & automated actuator. Established in 2009, J-VALVES supplies bulk large-size floating ball valves for chemical, oil & gas industrial projects with full API 6D certification.

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.

J-VALVES manufactures Class 600 WCB floating ball valves for oil & gas extraction, pipeline transportation and refinery plants. WCB carbon steel features high pressure & corrosion resistance, floating seat design ensures zero leakage. Our green standardized workshop complies with API 6D, custom valve solutions available.
