4.4.4 Installation with Varec’s UNI flange
Varec’s UNI flanges are designed for non-pressurized operation respectively max. 1 bar
absolute pressure. The number of bolts has sometimes been reduced. The bolt-holes have been
enlarged for adaption of dimensions, therefore, the flange needs to be properly aligned to the
counter flange before the bolts are tightened.
