Brass boiler drain valve

The Legend Valve 107-144 is a 3/4 inch T-521 brass boiler drain valve designed for plumbing professionals and maintenance technicians who need a reliable drain point on hydronic heating systems or water heaters. It provides a standard connection for attaching a hose during system draining or flushing.

3/4 inch T-521 brass construction

The single specification that determines fit is the 3/4 inch T-521 brass body, which sets the thread size and material compatibility for the installation. Buyers must verify that their piping matches this exact thread designation and that brass is suitable for the fluid type and system pressure in use.

Sustained exposure to heated water

Under sustained load the brass body resists deformation and corrosion from continuous contact with hot water in boiler applications. The valve is not intended for use as a primary flow control or throttling device over long periods, and buyers needing precise flow regulation should select a dedicated balancing or globe valve instead.

Questions about this item

What does the 521 model designation indicate when the valve is installed?

The 521 designation identifies this specific boiler drain valve design from Legend Valve, built with a brass body for standard boiler drain applications.

How does the 3/4 inch connection standard limit what piping can be used?

The 3/4 inch thread size requires matching 3/4 inch pipe fittings or adapters; it cannot connect directly to larger or smaller pipe diameters without additional components.

What physical space is needed to mount the 107-144 valve on a boiler?

The valve body and handle require enough clearance around the 3/4 inch boiler tapping to operate the drain handle fully after installation.
