Standard JIS 10K cast iron gate valves from domestic manufacturers are available from approximately 500 CNY per unit for standard configurations .
Premium brand configurations such as KITZ 10K cast iron gate valves are available from approximately 355 CNY for threaded models .
Japanese domestic market pricing for JIS 10K cast iron gate valves ranges from approximately $600 to $1,100 USD depending on configuration .
International wholesale pricing from Chinese suppliers for DN80 JIS 10K cast iron gate valves is available at approximately $24 to $25 USD per unit in bulk quantities (50+ pieces) .
For marine grade JIS F7364 cast iron gate valves with bronze seats and CCS/BV certification, prices reflect the enhanced material specifications and certification requirements .
Key factors affecting price include valve design (rising vs non-rising stem), seat material (integral cast iron vs bronze rings), certification requirements (JIS F7364 marine standard, CCS/BV/DNV), and brand positioning .
Technical Specifications
DN80 JIS 10K cast iron gate valves typically feature a cast iron body (FC200 or HT200) with a bronze seat (ZCuSn5Pb5Zn5 or BC6) for corrosion resistance and extended service life . The wedge is cast iron, and the stem is brass (C3771BD) or SUS403 stainless steel .
Key dimensions for JIS F7364 10K DN80: flange diameter 185mm, bolt pitch circle 150mm, 8 x 19mm holes, face-to-face length 230mm, height 400mm, and weight approximately 33kg . Design standards include JIS F7364 for design and JIS F7400 for inspection .
JIS 10K vs PN16 Important Note
JIS 10K and PN16 flange standards are not interchangeable. JIS 10K flanges have different bolt hole diameters, bolt circle dimensions, and flange thickness compared to PN16 . Verify your existing piping system uses JIS B2220 10K flanges before ordering.
Applications and Selection Considerations
DN80 JIS 10K cast iron gate valves serve critical functions in water distribution and pumping stations, marine piping systems (ballast, cooling, firefighting), HVAC and industrial process lines, and oil and gas systems requiring JIS standard connections . When specifying a JIS 10K cast iron gate valve, confirm the valve design matches your application. For marine service, specify JIS F7364 with bronze seat and classification society certification . Rising stem (OS&Y) designs provide visual position indication; non-rising stem designs save space for confined installations.
Summary
DN80 JIS 10K cast iron gate valves provide reliable isolation for JIS standard piping systems, with prices ranging from approximately 500 CNY for standard configurations to $24-25 USD for bulk wholesale. The JIS 10K rating ensures compatibility with Japanese-standard flanges. Selection requires careful evaluation of stem design, seat material, and certification based on specific application requirements.
