I am looking for a simple manual cap that will fit the kind of radiator valve shown in the picture, which has a small spindle. Like the simple white plastic non-sensor caps here at these british sites:

Can't seem to find them in the U.S. Anyone know where they can be bought?

    Heads

    Oventrop and Danfoss make heads for the valve body. Try www.pexsupply.com

    can find sensors only

    Thanks. They seem to have only sensor-type. I'm looking for decorative white knobs without a sensor.

    Why would you want to do that?

    The whole idea behind the use of a TRV is to provide accurate and automatic control. The knob is only as good as the person operating it, and it will most probably be a 2 position valve (Open or Closed).



    The manufacturers usually ship the valve with them when they are new for construction/temporary use.

    got a lead ...

    Danfoss seems to make a manual handle, part #013G5002. Checking now with local marketing rep to find a supplier.

    why a manual handle on the valve

    There are threads on the valve -- I can control the depth of the spindle with the ugly (i.e. non-decorative) thread-protector cap, so I think its more than an on/off option when you use a manual valve. There are decorative versions.



    Why would I do this? Well, for one thing, a manual handle is about $150 cheaper for two radiators. It seems US prices for these components are much higher than they are in Europe.



    I also want to guarantee my wife that she won't get burnt if she accidentally bumps into the towel radiator. (She has a scar where she got burnt on a radiator when she was a kid and she is somewhat worried about the wall-mounted radiator.) I can control a manual valve to the point where it's almost off and the radiator is tepid. But I don't know how cool the sensor would let it go.
