Installations
Generally locate the valve five pipe diameters downstream from a
fitting; with two diameters downstream from the balancing valve
free from fittings. If a balancing valve is located downstream from
a circulation pump, allow a distance of ten (10) diameters between
the pump and balancing valves (as illustrated below).
