V47AR-2
The Johnson Controls V47AR-2 Temperature Actuated Modulating Valve is a device element that delivers precise temperature sensing in HVAC systems. It is most suitable where temperature stability is desirable because the valve operates in the range of between 115°F and 180°F. This modulating valve has a unique characteristic of changing flow rates so that it can only maintain a constant thermal control on the medium that it regulates by its temperature. It is usually installed into heating and cooling systems since comfort and efficiency depend on stability and temperature control.
