How It Works:

Installed at the end of each supply branch, CircuitSolver® valves with ProPress ends automatically balance a domestic hot water  recirculation system by continuously adjusting flow to maintain a set temperature at the end of each supply branch or riser.

The valves eliminate manual balancing while ensuring immediate hot water delivery to each fixture and accommodating flow to meet demand variations.

For ease of integration into ProPress systems, ProPress ends can be added to any CircuitSolver® thermostatic balancing valve configuration. Featuring Viega® Smart Connect Technology, CircuitSolver® with ProPress easily identifies unpressed ends, expediting installation and system startup time.

Typical Applications:
