Since its founding in 1916, Itoseiko Corporation has specialized in manufacturing air conditioner valves, valve seats, and valve retainers for supply to air conditioner, refrigerator, and car cooler manufacturers.

We constantly undertake quality improvements and reforms, perform all processes internally as one continuous operation until completion, and set quality stability between each process as our highest manufacturing goal.

In particular, we have a special patent for heat processing which requires valve plate toughness, and have been enhancing our product lineup until today.

In recent years, we have installed various processing machines and enhanced our lineup of inspection equipment to comprehensively respond to demand for precision parts processing including surface grinding.
