Fuelles
The Bellows, can be used reliably in environments ranging from super-high vacuum to high pressure and from extremely low to high temperature, making them ideal for use in valves and elastic joints used in space develpment applications
Bellows Materials
Our standard products are made from SUS316L material. But even in the case of special
materials such as Hastelloy C-22, Inconel 625, titanium, M-Monel, nickel, etc.
Special Features of Bellows
Excellent flexibility, low spring constant, and extremely long life becuase of manufacture
from thin material.
Manufacture of desired dimensions is possible because of free decision of the inside
diameter in case of bellows produced by roll forming.
Use with the same flexibility as with a single layer is possible also for high pressure
because manufacture of two, three, or four layers also is possible.
Various demands can be met because manufacture from special materials also is possible.
Correspondence to customer-furnished metal fittings, small lots, and short delivery times
also is possible.
Correspondence from extremely low to high temperatures, from vacuum to high pressure,
and to various flow media is possible.
Bellows Applications
Absorption of vibrations and thermal expansion, expansion joints with variable installation
angle etc., thermostats, valve seals, bellows pumps, accumulator pressure detectors
(pressure switches, pressure gauges, pressure-operated equipment converting pressure to
electric power), accelerators, vacuum seals, instruments, control, radiators, shaft seals, etc.
