Johnson Controls V47AB-2 Temperature Regulating Valve 1/2 Inch 75-135°F

The Johnson Controls V47AB-2 is a 1/2-inch temperature regulating valve designed for precise control of water temperature in hydronic heating and cooling systems. This thermostatic valve automatically modulates flow to maintain consistent water temperature within the 75°F to 135°F range, making it ideal for applications requiring moderate temperature control.

Key Features:

• 1/2-inch NPT connection size for standard piping systems
• Temperature control range: 75°F to 135°F (24°C to 57°C)
• Self-contained thermostatic operation requires no external power
• Brass construction for durability and corrosion resistance
• Direct-acting valve design for reliable temperature regulation

This valve is commonly used in domestic hot water systems, radiant heating applications, and process temperature control where maintaining consistent water temperature is critical. The V47AB-2 provides automatic temperature regulation through thermal expansion of the internal element, adjusting flow as temperatures fluctuate to protect equipment and ensure optimal system performance.
