Taco 329-T3 Cast Iron Pressure Reducing Valve 1/2-Inch FPT

The Taco 329-T3 is a cast iron pressure reducing valve designed for residential and light commercial hydronic heating systems. This valve automatically reduces incoming water pressure to a preset level, protecting boilers, water heaters, and system components from excessive pressure damage.

Key Features:

• Durable cast iron construction for long-lasting performance
• 1/2-inch female pipe thread (FPT) connections on both inlet and outlet
• Factory preset to reduce pressure for fast-fill applications
• Ideal for use in boiler feed systems and closed-loop heating applications
• Compact design for easy installation in tight spaces
• Helps maintain safe operating pressures in hydronic systems

This pressure reducing valve is commonly used to automatically fill and maintain proper pressure in closed hydronic heating systems while preventing over-pressurization. The 1/2-inch FPT connections allow for straightforward integration into standard piping configurations.
