Johnson Controls V47AB-3C Temperature Actuated Water Valve 1/2" NPT 115-180°F

The Johnson Controls V47AB-3C is a self-contained, temperature-actuated water valve designed for automatic control of hot water flow in hydronic heating systems. This 1/2" NPT valve operates based on water temperature, opening and closing to maintain proper system temperatures without requiring external power or control signals.

Key Features:

• Temperature range: 115°F to 180°F actuation
• 1/2" NPT female threaded connections for easy installation
• Self-contained thermostatic element requires no external power
• Brass body construction for durability and corrosion resistance
• Normally closed valve opens as water temperature increases
• Ideal for hot water heating systems, radiant floor heating, and snow melting applications

This temperature-actuated valve provides reliable, automatic control in applications where water flow needs to be regulated based on temperature. The V47AB-3C is commonly used in bypass circuits, mixing applications, and freeze protection systems where maintaining proper water temperature is critical for system performance and efficiency.
