Hydronic Valves: 

All hydronic radiators are installed with a lock shield and a hand wheel. The lock shield is used to accurately set and ensure the correct water flow through each radiator. The hand wheel, otherwise known as an on/off valve, allows you to individually control the functionality of each radiator.

Thermostatic Valve Controls: 

Thermostatic controls can be added to the Giacomini valves to thermostatically control the desired room temperature at each radiator. Thermostatic valves further reduce the running costs of the hydronic system by restricting flow to individual radiators once they have reached the desired room temperature.
