Assembly and disassembly of the valves should always be conducted while the
system is cold and not pressurized (fig. A).
Install according to the flow direction indicated by the arrow on the valve body
(fig. B).
Can be installed in any orientation (fig. C).
In order to ensure measuring accuracy, the balancing valve must be installed by
keeping an upstream straight section of at least five diameters, increased to at
least ten diameters if the nearest device upstream is a pump (fig. D).
