Johnson Controls V47AC-39 3/4 Inch Temperature Actuated Regulating Valve 160-230°F

The Johnson Controls V47AC-39 is a 3/4-inch temperature-actuated self-regulating valve designed for automatic temperature control in hydronic heating and cooling systems. This thermostatic valve operates within a temperature range of 160°F to 230°F, making it ideal for hot water and steam applications.

Key Features:

• 3/4-inch NPT threaded connections for standard piping integration
• Temperature operating range: 160°F to 230°F
• Self-actuating design requires no external power source
• Proportional control maintains consistent system temperatures
• Brass construction for durability and corrosion resistance
• Direct-acting thermal element for responsive temperature regulation

This valve automatically modulates flow based on sensed water temperature, providing reliable temperature control for boilers, heat exchangers, unit heaters, and other hydronic equipment. The self-contained design eliminates the need for electric or pneumatic actuators, reducing installation costs and maintenance requirements.
