Moving Towards the Future and Ensured Technological Progress
~We provide valves through environmentally-friendly bellows technology that fits the new industrial age~
About Us
A combination of history and evolution
"Seamless Bellows"
It all began with the successful domestic manufacture of bellows.
February 1927.
On that day, the director of Ohno Bellows' predecessor "Ohno Kogyosho Limited Partnership," Keijiro Ohno, was the first person in Japan to successfully produce bellows, receiving a patent for them.
Now, close to 1 century has passed. The history of bellows and their evolution is the history of Ohno Bellows.
Quality
Quality/Technology
01
Bellows and Valves Produced In-house
The high-quality bellow seal valves from Ohno Bellows are stamped with a seal of quality assurance, and they are used in various "no leaks allowed" fields.
02
The Production of Original Bellows Valves
Production and customization to fit your use cases are available. We respond to customer needs through the cutting-edge technology used by our veteran technical team.
03
Perfect Customer Support
Each valve comes with a unique identification number that allows us to confirm when it was made and provide repairs even to valves that are several decades old.
04
Delivering Consistent Products
All important processing steps are performed domestically (at our Iwaki Factory). We have also developed an immediate search system for manufacturing history that allows for repeat creation.

Product Features
A safe future through "no leaks allowed."
For semiconductors, liquid crystals, food processing, vacuums, and other industries that require cleanliness, no impurities must be allowed into products. For nuclear power, petroleum oil, heavy machinery, and other fields that must always consider the environmental effects, leaks must be prevented.
Through the daily fulfillment of "no leaks allowed" by using both innovative ideas and traditional technology, we continue to manufacture bellows valves that contribute to a safe future.
