Since our company was founded in Tokyo in 1951, we have specialized in manufacturing cylinder valves for nearly 75 years. Cylinder valves have various characteristics depending on the type of gas they handle, some of which can be hazardous and potentially lead to disasters or endanger human lives if leaked. In particular, our stainless steel products are commonly used for toxic and corrosive gases.
Our primary principle is to ensure safety and security. To achieve this, we strive to provide superior technology from a fresh perspective, leveraging the expertise and experience we've developed over the years. Our commitment to innovation is evidenced by the several patents we hold.
Recently, as the global landscape has changed rapidly, the manufacturing industry has increasingly recognized the value of Japanese technology and quality.
To respond quickly and effectively to market demands, we continuously adopt the latest technologies and tools. However, we also emphasize to our employees that the foundation of our work is to "create products that our customers can use with peace of mind." We have been and will continue to be, dedicated to offering valuable products that prioritize safety and peace of mind.
