Why Choose the Johnson Controls V47AS-2?
The V47 Series from Johnson Controls is a trusted solution for self-contained temperature regulation in hydronic systems. The direct acting design responds immediately to temperature changes at the sensing bulb, opening or closing the valve to maintain the desired setpoint within the 160–205°F range. The cast iron body and ASME flange connections ensure long-term durability and leak-free performance in high-demand commercial environments. The included 6-foot capillary and Style 4 bulb provide installation flexibility, while the 1/2″ NPT external fitting simplifies integration into a wide range of piping configurations.
