Description
The Watts F344116 is a 1-1/2″ 340-3 Series thermostatic mixing valve engineered for reliable hot water temperature regulation in commercial and residential hydronic plumbing systems. Designed to blend hot and cold water supplies to a consistent, safe outlet temperature, this valve helps protect against scalding while maintaining system efficiency and occupant comfort.
The 340-3 Series is a trusted Watts platform built for demanding applications where precise mixed water temperature control is critical. The 125/210 designation reflects the valve’s operating temperature parameters — a maximum inlet temperature of 210°F and a mixed outlet setting up to 125°F — making it well suited for domestic hot water distribution, hydronic heating systems, and process water applications.
