Description

Antifreeze Valve 1 inch

The Antifreeze Valve is a reliable safety component designed to protect heating and solar systems from freezing damage. When system temperatures drop to a critical level, the valve automatically opens to discharge cold water and allow warmer fluid to circulate, preventing costly pipe and component damage. Made from durable brass, it offers long-lasting performance in demanding environments.

Ideal for hydronic heating systems, solar thermal setups, and outdoor installations exposed to freezing risk.

The antifreeze valve allows the circuit medium to be drained when its temperature reaches an average value of 3 °C.

This prevents ice forming in the circuit of a system, generally with a heat pump, avoiding potential damage to the

machine and to the pipes.The version with the air sensor allows the system to work in cooling mode, even when the

water temperature is approaching 3 °C. In these conditions the air sensor cuts in to prevent water drainage.
