Minimal Thermal Expansion
Using one-size-up and double the amount of body bolts reduces linear thermal expansion
and dramatically decreases the likelihood of leakage to the atmosphere.
Efficient Heat Transfer
The Habonim standard bonnet length design complies with BS6364 for non-cold-box
applications. The long neck bonnet insulates the stem seal from the low temperatures of
cryogenic fluids, thus enabling safe and long lasting seal service. A small gap between the
bonnet ID and the stem OD, ensurs a thick layer between the media and the stem seal.

The Habonim bonnet design comes in two optional versions. Both are designed to prevent
cryogenic liquids from reaching the stem seal. Habonim recommends installation in the
vertical position, but allows installation at an angle. The 12" bonnet can be installed up to 45°
from the vertical axis to maintain fully BS6364 compliant. The 6" bonnet can be installed up to
15° from the vertical axis.
