In industrial piping systems, with the continuous increase of pipe diameters and pressure ratings, the selection of ball valve structural forms becomes particularly critical. While floating ball valves are widely used in small-diameter working conditions, trunnion ball valves are often a more reliable and mature solution for large-diameter, high-pressure systems.

1. Understanding Pressure Ratings (PN16 to PN100)The pressure rating of a floating flange ball valve is expressed in PN, where PN16 indicates a valve rated for 16 bar (or approximately 232 psi) and PN100 indicates a valve rated for 100 bar (or approximately 1450 psi). These ratings are determined by
