Our genius is valves ®

The key is to keep water hot, and keep water moving.

The Thermal Circulation Valve responds to changes in system temperature and automatically adjusts to allow more flow (if temperature falls) or less flow (if temperature rises), and maintain the set temperature. During thermal disinfection, the Thermal Circulation Valve opens automatically to a secondary position to allow increased flow at the higher temperature.
