According to FCI (Fluids Control Institute), 34% of ball valve failures stem from improper installation or maintenance rather than manufacturing defects. I once saw a
Global oil and gas long-distance pipelines exceed 1.3 million kilometers, refinery daily throughput exceeds 100,000 barrels, and API 6D ball valves serve as the “pipeline
API 6D, published by the American Petroleum Institute, covers the full range of ball valves from NPS 2 to NPS 48 in design, manufacture, and
China’s valve exports reached USD 4.7 billion in 2025, with API 6D ball valves accounting for 38% of oil and gas valve export value. In
In 2024 I worked on a Southeast Asian gas pipeline project where the client required all valves to be API 6D certified. The original plan
In 2019, a pipeline fire caused by ball valve seal failure at Enterprise Products resulted in approximately $2.3 million in losses. API 6D ball valves
API 6D ball valves are pipeline valves designed according to the API 6D standard, mostly featuring a full-bore structure (bore diameter ≥ 95% of the
Choosing API certified ball valve manufacturers should verify their ISO 9001 certificate number, CE declaration of conformity and third-party testing reports (such as API 6D
Selecting ball valve manufacturers needs to audit API 6D certification, ISO 9001 system, focus on checking valve body material (such as ASTM A105), pressure rating
As ISO 9001 certified factory, we focus manufacturing floating ball valves. Specifications DN15-DN300, pressure 150-600LB. Every unit through “2 times strength + 3 times sealing”
