Technical Specifications
Production and Manufacturing Standards
JIS F7306, JIS F7308, JIS F7310, etc. : These are standards related to marine spherical angle valves and Japanese - standard angle - type globe valves. They specify requirements for applicable media (such as fresh water, air, other gases, oil, and steam with a temperature \(t \leq 205^{\circ}C\)), types (such as AJ and BJ types), and other aspects.
JIS F7324 : This standard stipulates the technical requirements and dimensions for marine ductile iron angle valves (including angle - type globe valves), covering materials (such as the valve body being made of ductile iron), nominal diameter, pressure, design, manufacturing, testing, marking, and other requirements.
Structural Length Standards
JIS B2002 : It is used to standardize the structural length dimensions of Japanese - standard flanged globe valves.
Flange Standards
JIS B 2210 : Applicable to the flange connection of some marine Japanese - standard angle - type globe valves.
JIS B 2212, JIS B 2214 : Commonly used as the flange connection size standards for Japanese - standard flanged globe valves.
JIS B 2239 : Involves the flange connection standard in marine Japanese - standard flanged cast - iron 1.0K globe valves and other products.
