Taco 5003-C3 3/4" Sweat Union Thermostatic Mixing Valve 85-175°F

The Taco 5003-C3 is a thermostatic mixing valve designed to automatically blend hot and cold water to deliver a consistent output temperature. This 3/4-inch sweat connection valve features union fittings for easy installation and maintenance without draining the entire system.

Key Features:

• Temperature range: 85°F to 175°F for precise control of mixed water temperature
• 3/4-inch sweat (copper) connections with union fittings for easy service access
• Thermostatic operation automatically adjusts to changes in inlet pressure and temperature
• Ideal for hydronic heating systems, radiant floor heating, and domestic hot water applications
• Prevents temperature shock and protects system components from excessive temperatures
• Durable brass construction for long-lasting performance

This mixing valve is commonly used in hydronic heating systems to protect components like boilers and heat exchangers, ensure proper operating temperatures for radiant floor heating loops, and maintain consistent supply water temperatures regardless of varying load conditions.
