The Johnson Controls V47AC-8C is a temperature-actuated, modulating water valve designed to regulate water flow based on temperature changes. It opens proportionally as the sensed temperature increases, delivering precise control in heating systems such as compressors, heat exchangers, and industrial equipment. The V47AC-8C is suitable for systems that require a 3/4-inch valve with an opening temperature range of 75°F to 135°F.
