Overview

1. SCOPE

This standard specifies the classification, marking, requirements, test methods, inspection rules, marking, packaging, and storage of stainless steel ball valves for ship use (hereinafter referred to as "ball valves"), where flange connection dimensions comply with CB/T 4196-2011, GB/T 2501-2010, and threaded connection dimensions comply with GB/T 7306.2-2000.
This standard applies to the design, manufacture, and acceptance of ship piping ball valves with nominal diameters from DN 15 to DN 150 and nominal pressures from PN 6 to PN 40, used for fresh water, seawater, oil, air, and acid/alkali corrosive liquids at temperatures not exceeding 150°C.
