1" x 1/2" Monoflow Tee Valve
The Legend Valve 302-204NL is a no-lead cast brass fitting designed for hydronic heating systems. It connects a 1-inch main line to a 1/2-inch branch circuit using Monoflow tee principles. This component suits installers balancing flow in radiant panel or baseboard loop layouts.
No-Lead Brass Construction
The valve body uses cast brass certified for no-lead compliance, addressing potable water safety requirements. Its T-570 Monoflow geometry creates a pressure differential that diverts flow through the branch without a separate circulator. The 1-inch by 1/2-inch sizing matches common residential manifold connections.
Replaces Standard Tees
This fitting replaces a plain tee when automatic flow diversion to a terminal unit is needed. The jump is worth it on retrofit jobs where adding a dedicated pump or zone valve is impractical. California Proposition 65 warnings apply regarding chemical content.

Questions about this item
What does the 1" x 1/2" sizing on the T-570 Monoflow Tee mean for pipe compatibility?
The tee accepts a 1-inch main line and a 1/2-inch branch connection for hydronic heating loops.
What are the physical requirements to install this cast brass tee in a manifold?
It needs a 1-inch female thread on the run and a 1/2-inch female thread on the branch, with clearance for the tee body.
How is the T-570 Monoflow Tee installed and what step is often missed?
Thread the tee into the manifold using pipe sealant on the 1-inch and 1/2-inch connections; the step often missed is orienting the branch outlet in the correct flow direction for the Monoflow design.
