ADV 9 Presettable thermostatic valves, self-closing in case of vandalism on the thermostat

For manual hydronic balancing at the radiator in central heating and cooling system with closed circuits. Installation in the supply pipe.
The integrated ADV 9 valve insert allows for infinitely adjustable presetting to adapt the volume flow to the required heat demand. The ADV 9 thermostatic valves are available in angle and straight versions.
The body of the valve is made of brass and the surface is nickel plated. The spindle is made of stainless steel.
The double function of these valves causes the valve to close automatically to 5% of the nominal flow rate if the thermostat is dismantled or destroyed (vandalism). This provides the frost protection function and prevents an uncontrolled rise in room temperature.
