Antifreeze valves, specifically designed to be used on heat pumps systems, are safety devices, with the aim to prevent ice forming<\/strong> of the fluid in the system circuit.<\/p>\n

These valves are particularly suitable to be used on monoblock heat pumps<\/strong>, meaning the ones equipped with an external unit directly connected to the hydronic circuit, through a supply and return pipe.<\/p>\n

The functioning of the valve takes place through the action of a sensitive element which detect the temperature of the fluid. In the event the temperature goes lower a pre-set temperature level (3\u00b0C<\/strong>), the valve automatically open, avoiding ice formation.<\/p>\n

The functioning of the valve takes place with the mechanical movement of the obturator led by the sensitive element, avoiding the need of electrical devices<\/strong> and making the valve functioning even during power outage.<\/p>\n
