This valve is typically used in air handling units on heating or cooling coils, and fan coil unit heating or cooling coils. Some other common applications include Unit Ventilators, VAV Box reheat coils and bypass loops. This valve is suitable for use in a hydronic system with variable flow. This valve is designed for modulating control using 2...10VDC or 4...20mA. (for 4...20mA control input a 500 ohm resistor is required). The valve is designed to fit in compact areas where proportional control is required using 24 VAC/VDC.
