Application
The PIQCV zone valves with its pressure independent technology are suited
for large commercial buildings where higher close-off and dynamic balancing
is required. Common applications include unit ventilators, fan coil units, VAV
reheat coils, fin tube casing, radiant panels and duct coils. The valve fits in
space restricted areas and can be assembled without the use of tools.
