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.
