Large Size Trunnion Ball Valve API 6D

In the field of industrial pipeline systems, especially in the petroleum, natural gas, and large-scale water treatment industries, large size trunnion ball valves that comply with API 6D standards have become the core equipment for fluid control and isolation. API 6D, formulated by the American Petroleum Institute (API), is a globally recognized authoritative standard for pipeline valves, defining strict requirements for the design, manufacturing, assembly, testing, and documentation of valves. For large-diameter pipeline projects, the stability, pressure-bearing capacity, and sealing performance of valves directly affect the safety and efficiency of the entire system.
