Description
The Taco Comfort Solutions 329-3 is a 1/2″ Female Pipe Thread (FPT) Fast Fill Pressure Reducing Valve engineered for hydronic heating systems. Designed to simplify system commissioning and routine maintenance, this valve allows technicians to rapidly fill and pressurize a hydronic loop to the desired operating pressure, then automatically transitions to standard pressure-reducing mode to maintain consistent system pressure during normal operation.
Key Features
- 1/2″ FPT connections for straightforward installation into standard hydronic piping
- Fast-fill functionality accelerates system startup and re-pressurization after service
- Automatic pressure-reducing mode maintains steady downstream pressure once the system is filled
- Compact, durable construction built to Taco Comfort Solutions’ quality standards
- Ideal for residential and light commercial hydronic heating applications
Application
The Taco 329-3 is well-suited for use in hot water heating systems, boiler loops, and radiant heating installations where reliable fill and pressure regulation are essential. Its dual fast-fill and pressure-reducing capability reduces commissioning time and helps protect system components from over-pressurization.
