ANTIFREEZE VALVE-CIMBERIO
The Cimberio Antifreeze Valve is an automatic frost-protection device designed to prevent freezing in hydronic and heat-pump water circuits. When the system water temperature drops to a critical level (typically around 3 °C), the valve opens to discharge water and protect pipes, heat-pump hydraulic kits, and outdoor hydraulic circuits from freeze damage. Built with high-quality brass components, it ensures reliable protection in residential and light-commercial installations.
