The company says a good example of this is its range of valves available in a bellows seal
design, such as its Type 808 bellows sealed
These non-vented bellows seal
from two sides, aiding in dual sealing and preventing in the accumulation of contaminants inside the leaflet.
Designed for steam, hot-water and heat-transfer fluid applications, the BE3L bellows seal
glove valve features forged steel construction and stainless steel bellows to with-J, stand 10,000 cycles.
feature bellows seal
design that replaces the throat packings and throat seal lubricant in traditional piston pumps.
Unlike a bolted seal, which pushes against the sealing material hardest under the bolts, a bellows seal
exerts the same force around the entire circumference.
In addition, the enhanced sealing and thermal absorption of the flexible bellows seal
component works well with lasers of various sizes.
The unit's smooth, crevice-free surface eliminates the risk of food or foreign matter being trapped, whilst the bellows seal
, used at the valve's stem, produces an hermetic seal that prevents product contamination.
