    i thought you normally wound it all the way out and then back in the 4 and a bit turns to factory setting? I'd have to get a box to check though. I would imagine if it was knackered it wouldn't turn and stop but rather keep moving?

    I've done a couple of TES5 danfoss valves which i think work the same way, with these you had to adjust the orifice to a set measurment before fitting, then install it in the valve, the adjustment was only used to tweek the superheat if needed.

    This was a two piece valve, with a brass block for the pipe connections, into which the orifice went and the chrome bellows adjuster assembly goes on top.

    Re: knackered ex valve ?

    Yes it one of those with a 90 degree brass block with the solder fitting and 4 allen screws Jon and Al I tried to get some details from danfoss tech but no luck, thing is I thought that these had a limit as to how far in or out they went
    initially I thought it went in and stopped at a 1/4 turn in and thought well I will take it out 2 turns things improved but I run out of time as I had the heating of, so I shut it down and put the heat back on so I decided to check out the valve again but I can turn it in or out 10 full without hitting a stop so are these on a cam type affair that lifts or drops the orifice needle,if so I can see what meant by setting it prior to fitting, help me out here guys

    The "cage" or orafice has to be measured to determine factory settings. The length/ height in mm should be available through refrig. wholesalers. Vernier calipers are the best way i find to set them.. Mike.

    Re: knackered ex valve ?

    So it has to be assembled with the proper setting prior to to fitting?

    Yep. What orifice size do you have, and refrigerant are you using?

    Also you have to use the lifting tool when assembling components , to dis-engage the adjusting stem/ cog to the orifice assembly. Other wise everything gets bent.
