FAQ
Is the JIS 20K designation enough to approve this valve for my project?
Provide the design, flange and inspection requirements in the project specification together with the operating conditions. Request the selected valve rating, drawing and material documents for approval; the JIS 20K label alone does not confirm every requirement of the offered assembly.

The page identifies a flanged bonnet and SCPH2, SCS13 and SCS14 material references. Identify the required material grade and ask for the exact body, closure and seat schedule for the quoted assembly. Confirm the selected materials for the actual medium and operating conditions.
What installation information should I send for this JIS 20K valve?
Send the piping flow direction and orientation, mating flange details and available installation space. Include the operating medium, pressure and temperature, and any existing valve identification. Use the selected assembly drawing to check face-to-face fit and access before accepting the installation arrangement.
