In the realm of fluid control, the Trunnion Mounted Ball Valve (TMBV) stands as the gold standard for high-pressure and critical isolation applications. Unlike floating ball valves, where the ball is held against the seat by line pressure, the trunnion design secures the ball at the top and bottom. This engineering choice is fundamental for safety in energy, petrochemical, and cryogenic sectors.
As global energy infrastructure faces the dual challenge of aging assets and the transition to cleaner energy sources like hydrogen and LNG, the demand for high-integrity, zero-leakage valves has surged. Our factory aligns with these macro trends by integrating advanced materials and automated precision machining to meet international standards such as API 6D and API 607.
Our commitment to E-E-A-T principles is reflected in our manufacturing lifecycle:
Operating a manufacturing hub in China while servicing global markets requires rigorous adherence to local and international regulations. We ensure compliance with ASME, ISO, and CE directives, providing localized technical support and documentation to ensure our valves integrate seamlessly into your regional infrastructure.
Trunnion valves are designed for high-pressure, large-diameter applications. They require lower operating torque and offer superior sealing reliability because the ball is fixed, reducing wear and leakage risk.
DBB provides two seating surfaces that, when in the closed position, seal the fluid at both ends of the valve, with a cavity between them that can be bled to confirm integrity.
Yes, we have developed specialized series with high-integrity sealing and compatible materials to mitigate hydrogen embrittlement and leakage in new energy infrastructure.
