Taco 334-T3 Boiler Feed Valve 1/2" NPT Dual Control Pressure Reducing Valve

The Taco 334-T3 is a dual control boiler feed valve designed to automatically feed and maintain proper water pressure in closed-loop hydronic heating systems. This combination valve integrates both a pressure reducing valve and a backflow preventer in a compact cast iron body.

Key Features:

• 1/2" NPT female threaded connections for easy installation
• Cast iron construction for durability and long service life
• Dual control design combines pressure reducing and backflow prevention
• Automatically maintains system pressure by feeding water as needed
• Adjustable pressure setting to match system requirements
• Bypass valve for manual system filling
• Strainer included to protect internal components from debris

This valve is essential for maintaining optimal pressure in boiler systems, preventing both over-pressurization and low pressure conditions that can lead to system damage or inefficient operation. The integrated backflow preventer protects the potable water supply from contamination.
