Legend Valve 110-213 1/2" T-425 Circulator Valve accessory
1/2" T-425 brass circulator valve controls flow in hydronic heating systems
- 1/2 inch T-425 brass circulator valve for hydronic systems
- Legend Valve brand ensures reliable heating component performance
- New condition guarantees full factory specification compliance
- California Proposition 65 warning indicates chemical safety awareness
- Model 110-213 identifies exact replacement part for maintenance
Application & fit
This brass circulator valve is built for hydronic heating systems that require a 1/2 inch connection. It suits installers and maintenance crews working on residential or light-commercial boiler loops. The component is not intended for potable-water plumbing, high-pressure steam lines or any service outside closed-loop heating circuits.
Thermals, noise & power
The valve body handles the temperatures and pressures normal to forced-hot-water circulation without external power or moving parts that generate noise. Operation is silent because flow control is mechanical and there is no motor or solenoid. No electrical draw is added to the system.
Decisive specification
The 1/2 inch T-425 brass construction determines whether the valve matches the piping and pressure class of the job. California Proposition 65 notices apply because the alloy contains a listed chemical. Verify the connection size and material compatibility before ordering.

Questions about this item
How is the 1/2" T-425 circulator valve installed, and which step is often missed?
Apply thread sealant to the 1/2" male threads, tighten with a wrench on the brass body flats, then verify the flow arrow matches the system direction — skipping the arrow check is the common error.
What maintenance or replacement will the T-425 valve need over time?
Inspect the brass body and seat annually for mineral buildup or corrosion; replace the valve if leakage appears at the stem or seat, as internal parts are not serviceable separately.
What limit appears first on the T-425 circulator valve during sustained hot-water circulation?
The brass construction and seal materials set the practical temperature and pressure ceiling; continuous operation beyond the rated service range will accelerate seat wear and stem packing degradation first.
