Key selection criteria include:
- connection class JIS 16K
- brass compatibility with process media
- operating pressure and temperature
- leak-tightness in closed position
- access for operation and maintainability

Specification Note
This product is listed as F7388 / 16K / cock type S. In JIS technical catalogs, F7388 may also refer to bronze globe valve S & U type, JIS 20K. For procurement or technical submittals, always confirm execution, DN, pressure class, and end connections from drawing or datasheet.
Maintenance
Periodic inspection should include smooth handle rotation, leakage in closed position, sealing surface wear, and scale deposits. For seawater lines, verify material compatibility and perform more frequent functional testing.
