TRV Head Identification

[tompparker]

Hi all,

Would be grateful for your help in identifying the TRV head in the photos.

Have tried fitting a Drayton RT212 (M30 x 1.5), but while it almost fit, the new head seemed slightly too small to gain purchase on the valves's thread.

Thank you!

I have used energenie, eQ-3, and Kasa all of which seem to work out the stroke without needing any help. It needs setting, so the pin is retracted, but they came with all that was needed to fit a whole range of valves, at £15 for the eQ-3 seems pointless using the old non-programmable wax type, may as well fit a programmable one.

Hard to tell exactly, could be an old Siemens could be Honeywell could be an other.

I think that is a Wickes 'own brand' one about 20 yrs ago. I've just replaced one on my own system that was leaking around the pin.
