during the setup. Thanks to the valve block it is possible to dismount
the VEGADIF 65 without interrupting the process. This means higher
plant availability and simpler setup or maintenance.
The 3-fold valve block with flanging on both sides enables a mechani-
cally stable connection between the VEGADIF 65 and e.g. the tapping
points or the flange plate of a pitot tube. With the five-fold valve block,
two additional valves allow blowing out the process lines or checking
the VEGADIF 65 in installed condition.
The following illustration shows the connection of the 3-fold valve
block.
