Description
The Johnson Controls V47AA-1C 3/8″ Actuated Modulating Valve is a fluid control component used to regulate the flow of water with temperature changes in HVAC systems. Its main operation is to keep the valve opening in the range of 115°F to 180°F to ensure that water or glycol temperatures are desired. The internal temperature sensing system uses an adjustment of the valve position in reaction to a thermal expansion of the actuator, permitting equal circulation. It helps in the regulation of fluid flow and helps in the control of stable temperature.
