Removing a radiator with a daisy wheel valve

chateauneufdupape

Hi, I want to remove a radiator, but am not sure how to turn the supply off. The locking shield nut just seems to keep turning. I think it is called a daisy wheel. It seems to work on a wedge shape arrangement. You can turn it clockwise forever, but you can only turn it anticlokwise once as it hits a stop. How do you know when it is turned off? i.e. in what position is it off?

Take the plastic cover off the spindle as the plastic is probably strained and so wont turn the valve, and then get some pliers and turn the spindle fully clockwise to isolate the water supply.

Hi
Thanks for the reply. However it is not this type of spindle.

Maybe someone else can help then, or maybe you could ppost a picture of it?

There are a couple of images here and here. As I turn the spindle clockwise, it gets a bit stiffer until it reaches the ledge. Once passed this ledge, it turns freely again until it reaches it again. If I turn it anticlockwise it will turn freely until it hits the base of the ledge.

It does say "shut" on the valve ? maybe it is shut when you hit your "ledge"?

Is there a screwdriver slot in the centre of the valve when looking into the threaded part? If so then turning that clockwise will close off.

You will be able to tell if/when it is shut off by opening the bleed valve, water pressure will stop as soon as the pressure is relieved, obviously you will need to close the inlet valve as well
