Differences Between JIS Flanged Ball Valves and DIN Flanged Ball Valves

Item	JIS Flanged Ball Valve	DIN Flanged Ball Valve
Standards Used	Japanese Industrial Standards (e.g., JIS B2220, JIS 5K/10K/16K/20K)	German/European standards (e.g., DIN 2501, DIN/EN 1092-1, PN10/16/25/40)
Pressure Rating Format	Rated by K (kgf/cm²): 5K, 10K, 16K, etc.	Rated by PN (Nominal Pressure): PN10, PN16, PN25, PN40
Flange Dimensions	Follows JIS dimensional system; flange OD and bolt circle often differ from DIN	Follows DIN/EN 1092-1 system; generally different from JIS in all key dimensions
Bolt Pattern (Number/Size/PCD)	Bolt quantity, bolt hole diameter, and pitch circle diameter differ from DIN; uses JIS bolt sizes	Bolt pattern defined by DIN/EN; typically incompatible with JIS bolt dimensions and spacing
Interchangeability	Compatible only with JIS flanges; not interchangeable with DIN or ANSI	Compatible only with DIN/EN flanges; not interchangeable with JIS
Sealing Face Type	Mostly RF (Raised Face)	RF, FF (Flat Face), RTJ depending on DIN/EN standard
Typical Regions Used	Japan, Taiwan, parts of Southeast Asia	Europe, China, Russia, Middle East, and regions using EN/DIN systems
