When evaluating ball valve factories for procurement, I typically look at three core dimensions: whether API 6D certification is complete, whether material test reports for
Duplex stainless steel, with PREN ≥ 35 and yield strength approximately 450 MPa, is the preferred valve body material for high-chloride and high-H₂S service conditions;
According to ASME B16.34, ball valves account for approximately 38% of the global pipeline isolation valve market — the differences in seat contact stress, bearing
According to the Norwegian Petroleum Safety Authority (PSA) 2022 report, ball valve-related downtime accounts for 17.3% of all pipeline equipment failures, with an average cost
Ball valves rank among the most common isolation devices in piping systems worldwide, and the design differences between floating-ball and trunnion-mounted types directly determine pressure
