Scope

Scope: This document specifies the evaluation procedures and requirements for quality grading of control ball valves, evaluation methods, and quality grading. This document applies to shut-off type O-ring ball valves (solid ball) with a medium temperature above -29°C and a pressure rating of PN16 to PN420 (Class 150 to Class 2500). Control ball valves include fixed ball hard-sealed control ball valves, floating ball hard-sealed control ball valves, fixed ball soft-sealed control ball valves, and floating ball soft-sealed control ball valves. This document does not apply to high-frequency ball valves with a switching frequency of ≥10,000 times/year. Main technical content: 1.
