Description
The Johnson Controls V47AR-1 is a direct acting, temperature actuated water regulating valve engineered for precise hydronic and HVAC system water flow control. Built with a durable cast iron body and a 1-1/2″ ASME flange connection, this valve is designed to handle demanding commercial and industrial applications where reliable temperature-based water regulation is essential.
The V47AR-1 responds directly to sensed temperature changes via its remote bulb and capillary assembly, modulating water flow to maintain system setpoints without the need for an external power source — making it a dependable, self-contained solution for a wide range of heating and cooling water circuits.
