In industrial pipeline systems, selecting the correct ball valve type is critical for ensuring safe operation under different pressure conditions. Two of the most widely used designs are the Floating Ball Valve and the Trunnion Mounted Ball Valve. Although both are designed for shut-off and flow control, their pressure-handling capabilities differ significantly.

In modern pipeline systems, the Double Block and Bleed (DBB) Ball Valve plays a critical role in ensuring safe isolation, pressure control, and leakage prevention. One of the most important factors determining the performance, reliability, and service life of a DBB ball valve is material selection.Different industrial environments—such as oil & gas transmission, LNG processing, offshore platforms, petrochemical plants, and chemical industries—require carefully engineered material combinations to withstand pressure, temperature, corrosion, and erosion.
