Considering a multi-zoning office with separate constant volume systems and zone control on every solar exposure, private office & special occupancies; can modulation of HVAC system in response to space demand be controlled on chilled water side through 2-way modulating valves with a contant or Air supply modulation through VAV is a must.

I'm not sure I understand the question, but I'll take a shot at answering. To my knowledge the fan system is what is required to modulate. So controlling the chilled water valve would not achieve this.

Fluorotherm did a wonderful job, I am happy to recommend their products. Heat Exchangers replaced our old tank(s) heating system. We are saving money with the new products.
