The FlowCon Green series is a range of pressure independent control valves that are two-way, modulating to accept digital or analog input signals. The valves accept 0(2)-10V, 3-point floating or ON/OFF input signals. Each valve has an adjustable maximum flow rate setting maintaining a full stroke to enable flow limitation and balancing to the coil or zone that the valve is controlling.
For use in fan-coil units, VAV applications and cooling ceilings for activation of heating or cooling. They are available in three different valve housings, i.e. FlowCon A, AB or ABV.
