The Johnson Controls V47BD-3 is a 1-inch temperature-actuated modulating water valve designed to perform reliably in heating systems. As the temperature rises, this valve opens, acting directly to modulate water flow. End connections are NPT threaded, ensuring secure installation within piping systems.

The valve’s functionality is optimal within an opening point temperature range of 46 to 82°C. Accompanying the valve is an 11/16 x 6 inches bulb size that plays a crucial role in detecting temperature changes. Its robust capillary is 10 feet long, made from durable nylon armor, providing effective protection and flexibility.

The maximum allowable bulb temperature is -6.6°C above its rated range, allowing for safe operation under various conditions. Moreover, the valve can manage a maximum water temperature of 77°C while withstanding supply pressures of up to 150 psig. Designed for use in heat exchangers, the V47BD-3 efficiently regulates water flow to maintain desired operating temperatures, making it an essential component for effective thermal management.
