TempFlow thermostatic balancing valves automatically adjust to maintain domestic hot water temperatures, helping deliver fast, consistent hot water throughout a recirculation system. Installed after the last hot water device in each recirculating loop, the valves self-adjust to balance recirculated flow and heat loss in each controlled zone. The result is easier system balancing, reduced installation and maintenance costs, and more consistent hot water performance.
