If the valve on your radiator is not a thermostatic one, you can replace the old hydraulic valve and then install the Smart Valve.
IRSAP offers a full range of thermostatic valves, suitable for all hydraulic heating systems. However, we recommend the replacement work to be carried out by a professional: to replace the hydraulic valves or request a simple advice on those most suitable for your system, you can contact one of our technical experts in your area.
