Application
The V47AE-2 is ideal for use in hot water heating systems where automatic, temperature-driven flow regulation is required. The self-contained sensing system uses the 6-foot capillary and immersion bulb to detect water temperature and modulate flow accordingly, helping maintain consistent system temperatures and improving overall hydronic system efficiency. The 1/2″ NPT external fitting allows the sensing bulb to be installed in a thermowell or pipe fitting for accurate in-line temperature measurement.
