PINTOSSI antifreeze valve 1 1/2" - 1 1/4"

PINTOSSI antifreeze valve 1 1/2" - 1 1/4"

The anti-freeze valve is a key safety component designed to protect heat pump systems, especially those of the monobloc type, from damage caused by freezing of the heat transfer fluid. This valve automatically activates the drain of part of the liquid from the heating system in the event that its temperature drops below the critical limit of 3 °C, thereby effectively preventing the formation of ice. Its unique mechanical design includes a damper controlled by an integrated sensor, which eliminates the need for electrical power and ensures continuous functionality even during power outages. In addition, thanks to the practical double thread, this valve offers the possibility of easy connection both from the outside and from the inside, which facilitates installation and increases the versatility of use.
