The Japanese standard flanged ball valve standard is Japan's original JIS standard (Japanese Industrial Standard). The pressure of the Japanese standard flanged ball valve is divided into 10K, 20K, etc., many of which are made of bronze. Compared with the national standard, the requirements are more high.

     Japanese flanged ball valves are not only imported products, but are actually more domestically produced, that is, the Japanese Industrial Standards (JIS) are used for valve production and inspection during domestic production. In addition to domestic use, qualified products will also be exported.
