Engineering Analysis: PN16 vs. Class 150 Valves: Pressure Ratings & Flange Drilling Standards
Selecting the correct valve design and specification prevents costly pipeline failures, water hammer shock, and premature seal degradation. Below is the technical breakdown compiled by Baoming Valve R&D Team.
Technical Summary: Always verify pipeline pressure nominal rating (PN/Class), flange drilling dimensions, medium temperature, and body coating (FBE ≥ 250 µm) before issuing B2B procurement schedules.
