Make sure that the valve is fully open so that the radiator can reach its maximum temperature. As others have said, the valve is stuck and that's why the knob not there What is a lock shield valve

Can i balance the heating system by just adjusting the thermostatic radiator valves
My valve is not working and so on
In this video i will try to explain all. Turn the valve counterclockwise to add heat, and clockwise to close off the heat The 0 setting means no heat, though the radiator remains powered Turn the radiator dial counterclockwise to turn it on
The control valve is located near the bottom of most radiators. Turning the valve counterclockwise will increase the heat, and turning it clockwise will reduce the heat Note that this will not turn off the water or electrical flow to the radiator. Seems a simple thing to do, but if you get confused over which way to turn them, here is how to do it
Jan asked me to put this one up, as she always gets in a muddle which way they should.
Most modern radiators come with valves that have temperature gauges, which can be controlled by simply turning a knob You should check that your valves are open by turning the knob at the bottom corners of your radiator in an anticlockwise direction, and then back again. Once the water is on, slowly turn the first knob to the left until you hear water running through the radiator Then, turn the second knob to the left until the desired heat is reached.
If the radiator is off, it shouldn’t make any banging sounds. If you have a traditional radiator, you will need to turn the knob on the valve to the right to turn on the heat If you have a more modern type of radiator, you will need to use the thermostat to set the temperature you want the room to be.
