Description of PBCOmpac
The groove designed for holding the sealing element (O-ring) is dimensioned
in such a way that the erection bolts can be tightened to the point of full-
surface contact with the contact areas.

COMPAC
flange connections with flat gaskets and do not need to be attached as
tightly. A complete sealing is achieved using weaker screw tightening forces.
With the establishment of the full-surface contact of the contact areas, a no-
ticeable resistance can be felt which signals the proper assembly and suffi-
cient screw tightening forces.
During the assembly of the COMPAC
danger that the screws will be overstrained when being assembled.
Furthermore, the sealing element is automatically subjected to the correct
conditions (forming and compression) with the establishment of the full-
surface contact of the contact areas, whereby unintended damage to or
overloading of the sealing element is impossible.
The groove for holding the sealing element is extensively protected during
storage, transportation and assembly.
Light scratches on the flange contact areas, even in the area of the groove,
can be borne by the COMPAC
effect because there is an enormous compressive force pressing against the
sealing element on the flange surface lying opposite the groove and the
sealing element can thus fill up scratches or depressions with the sealing
material.
Principle of the COMPAC
This new flange generation is indispensable for the interaction between me-
chanical engineering and measuring technology. The COMPAC
the joining element to the measuring technology and fulfils all requirements
for recording an accurate reading.
With a lighter design and smaller installed size, the new flanges offer more
sealing efficiency and security against leakage.

- Previous DIN flange DN 250, PN 100, weight 81.40 kg
