Bad TRV?

It sounds like your valve is installed backwards.

The TRV should be installed on the supply side of the rad with the arrow on the valve body going towards the rad.

    Little help please

    About three years ago I went to TRV's(Danfoss) on all the rads in my hot water system.All work flawlessly except on my very short under window rad in the dining room. It seems that when the head calls for the TRV to open(or maybe even to close, can't tell) the valve starts to stutter. Ihave replaced the head but the problem continues. Any ideas?

    In checking it out when I got home this evening the valve is plumbed in on the high connection on the rad and the opposite end leaves at the bottom of the opposite end.

    The valve's arrow must be the same direction as the flow or the problem you describe is exactly what will happen. Reverse the direction of the valve so that the arrow points in the other direction and the problem will be solved.
