Can anyone identify these TRVs that we have in service, fitted by previous owner(s). Better still can anyone say if these are compatible with Honeywell HR80 actuators? We have two different sorts in service, most are this sort, branded "Reglo" ...


But there are also two Danfoss both of the type shown here ...

Thanks in advance, I'm looking forward to getting some decent controls in place now that the pipework is sorted out (you wouldn't believe the system the previous owner left us with!).
