The Leonard Valve TM-26-LF-RF is a 3/4″ lead-free thermostatic mixing valve engineered for precise hot water temperature control in commercial and residential plumbing and hydronic systems. Featuring sweat (solder) end connections and a maximum working pressure of 125 PSI, this valve is built to deliver consistent, safe outlet water temperatures by blending hot and cold supply lines — protecting end users from scalding while maintaining system efficiency.
Constructed to lead-free (LF) standards in compliance with NSF/ANSI 61 and 372 requirements, the TM-26-LF-RF is well-suited for potable water applications where regulatory compliance is essential. The thermostatic element automatically compensates for fluctuations in supply pressure and temperature, maintaining a stable mixed outlet temperature without manual adjustment.
