1-1/4" Brass Convector Valve

The Legend Valve 110-146 is a 1-1/4 inch T-433 brass convector valve designed for hydronic heating systems. It serves as a control component for hot water radiators or convectors in residential and commercial installations. The valve is supplied new and ships directly from the manufacturer.

T-433 Model Designation

The T-433 model number identifies the specific valve pattern and thread configuration required for correct fitment. Matching this designation to the existing piping or radiator tapping is the critical step before purchase. No other size or thread variant is associated with this part number.

Installers Replacing a T-433 Valve

This valve suits heating engineers or DIY installers replacing a failed T-433 unit on 1-1/4 inch pipework. It is not for systems requiring a different thread standard, a smaller or larger nominal size, or an alternative valve body pattern. Buyers needing a different connection type should look at other valve models.

Questions about this item

What does the 1-1/4 inch size mean when I install this valve in my system?

The 1-1/4 inch measurement indicates the pipe thread size, so the valve connects directly to matching 1-1/4 inch threaded piping without adapters.

How does the T-433 brass construction affect the valve's pressure and temperature limits?

Brass body and trim provide corrosion resistance for hydronic heating water and typical residential boiler pressures within standard convector valve ratings.

What clearances or mounting hardware are required to fit this 110-146 convector valve?

The valve threads onto 1-1/4 inch pipe; allow enough space for the handle to operate fully and ensure pipe alignment supports the brass body weight.
