Admissible forces and bending moments
Forces from evacuating the system, from the weight of other components or
from baking can lead to deformation of the valve body and to malfunction of
the valve. The stress has to be relieved by suitable means, e.g. bellows
sections.
The following forces or moments are admissible:
DN (nom. I. D.)
Axial tensile or com-
pressive force «FA»
Bending moment
«M»
