Water-side control of heating and cooling systems for AHUs and water coils. Equal Percentage/ Linear: heating and cooling applications.
Operation
The Electronic Pressure Independent Control Valve is a two-way valve that maintains constant flow regardless of pressure variations in the system.
Product Features
Provides constant flow regardless of pressure variations in the system. Maximizes chiller ΔP, preventing energizing additional chillers due to low ΔT. Simplified valve sizing and selection, no Cv calculations required.
