how to shut off the radiator valve

[Farooko]

Hi All

Could you please have a look at the attached picture of the radiator valve and let me know how to shut it? I want to take the radiator off the wall for decoration.

many thanks

It's a TRV that has had the head removed. To shut it off the centre pin needs to be depressed. Plastic caps are available that screw on in place of the TRV head to do just that.

If you have the TRV head, putting it back on and turning it down to the frost setting, should also achieve the same thing, but it can be risky if the temperature drops low enough for the TRV to open.

Stem, many thanks. You made it crystal clear for me now .

Hi, would you know the make of the valve in your photo as mine looks the same but has the wrong head. I was told it’s a Peglar which I purchased but the new one has a hexagonal shoulder as opposed to my original that’s square like yours?

I think yours is an older version ,not been produced for many years. Change the whole valve time !!

@stem that pic is a wheel head and wont fit a TRV, the caps you are referring too are called decorator caps, they come as spares with most TRVs but everyone throws them away

Well I had nothing to loose so I trimmed some of the plastic on the underside of the new head and it’s fitted perfectly and I working fine too. Result

Sorry @ianmcd I don't understand that. When I take off a TRV head, I then screw the plastic cap on in its place and it closes the valve and lets me remove the radiator for decorating without any water escaping from the valve, which is what the OP wanted to do.

my apologies @stem , I have just googled and it seems that you can indeed get decorators caps with +/- on them, never seen them only ones I have seen are blank and completely closed or removed
