API valve standards differ but the most prominent one is the API 6D. API ball valve designs in this category follow set specifications and manufacturing recommendations in terms of size and structural detailing. They are rigorously inspected, tested, and documented before approval.
Series - 150 To 900
As a certified API ball valve manufacturer, DAGO adheres to all these guidelines and maintains exceptional standards of production. The recommended API 6D ball valve design features make them suitable for flow control in long pipelines, overpressure relief, and the detection of leaks. Each of our units delivers high standards of media flow management and is certified as a fire safe ball valve. While they are primarily designed for the petrochemical industry, their precision and efficiency also make them ideal for related sectors with similar needs.
