operating parameters
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). To save space, the valve may be used
in the angled configuration as an elbow.
