Compatibility: Specific Giacomini manual radiator valves

How to use
To use the Giacomini R74 key, align the opening of the tool with the adjustment spindle of the radiator valve. Once securely seated, turn the key slowly in the desired direction to increase or decrease the flow of the heating medium. Ensure that the valve is not forced beyond its natural stop point to prevent damage to the internal components. After the desired adjustment is achieved, remove the key and store it in a safe, dry place for future use.
What to consider before purchase
Verify the compatibility of your existing radiator valve with the Giacomini R74 interface
Ensure the valve is a manual type rather than a thermostatic head model
Confirm that the valve spindle is not damaged or obstructed before attempting adjustment
Usage recommendations
Regularly inspect the valve spindle for signs of corrosion or debris before using the key to ensure smooth operation and to prolong the lifespan of both the tool and the valve.
