The Johnson Controls V47AR-2 is a temperature-actuated, modulating water valve designed to regulate water flow based on temperature. This valve is ideal for heating applications and opens gradually as the temperature at the sensing bulb increases. It provides proportional water flow control to maintain stable operating temperatures in heat exchangers, compressors, and other industrial systems.
