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.

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.
