The VP229E is an automatic balancing and control valve that provide flow limitation with full control authority over hydronic regulation. It provides stable flow regulation regardless of pressure fluctuations in the system and is adjustable flow limitation set point. Applications are temperature control of chillers, airhandling units, heat exchanges and terminal units such as fan coils, induction units and radiant panels. Reduced Energy Consumption, Improved Comfort, Reduced Pumping Costs, Reduced Installation Costs, Easy and quick Comminssioning, and Improved Reliability. Low Flow.
