Quality, technique

Speak in-house production; Rose and Valve

It is the bellows seal valve of the high quality which incorporated the bellows for exclusive use of the valve which we which developed the domestic first metal seamless bellows in 1927 produce based on the technique that accumulated for many years. I am used in the wide "fields where it must not leak" such as atomic energy, electricity, a semiconductor, chemistry and the vacuum, and superior features are evaluated.

Lineup to the wide field

The bellows valve product is currently used in various condition bottoms (high pressure, vacuum, very-low temperature). I will have a diameter at 300A from a miniature in future while further innovation advances to cope with various demands of the user.
