While some radiators just have an on and off switch, a thermostatic radiator allows you to control the amount of heat it puts out. If your radiator doesn’t have a thermostatic valve or is a 1-pipe system, you can skip this step.
If you don’t have a thermostatic valve, all you need to do is turn this valve.
Let the radiator cool down for at least an hour before touching it.
Not all lockshield valves will have a screw. Check the valve beforehand to determine if you need a flathead or Phillips head screwdriver.
If your valve cap had a screw, store the cap and screw together.
The metal valve may be hot, so do not touch it with your bare hands.
