Turn your central heating on and see which pipe gets hot first, this is the flow pipe into the radiator. This is the end you fit the thermostatic valve with the head vertical. If there is a lack of space then install the valve with the head in a horizontal position but on the return pipe. Failure to do so will give rise to a chattering valve when the head reacts to the temperature and starts to shut down. Multi directional valves mean they can be fitted to either end of the radiator as long as you follow the guidelines above. Fitting the valve horizontally or vertically on the wrong end will only become a noisy nuisance.
Good Luck.

With the new type Thermostatic valves in doesn't make any difference which end you fit the valve. On the older valves the thermostatic one had to be fitted on the Flow to the radiator. Hope this helps.

The valve with the thermostat should be fitted to the flow, the flow is the first pipe which gets the hottest, when the room gets to the required temerature the valve will close off, stopping anymore heat going to your radiator.
Thats what I was told whilst doing my apprenticeship but that was over 20 year ago and the valves are more sophisticated now.
Hope this helps.

The flow (hottest) pipe is the one which the water enters the radiator by, and is the preffered connection, although many modern valves e.g. Danfoss RAS-C2 are suitable for either flow or return pipes, but you have to turn a ring on the body to suit the direction.

The thermostatic valve should always be on the outlet side. It keeps the radiator fully flooded all the time.

It makes no difference which end the valve is on. It will work on either end. It just regulates the temperature of the radiator.

Flush the entire system. Are the radiator hoses in good shape. They could be collapsing under the pressure.
