Danfoss ras c2

[Mikeyward]

I'm looking at fitting the Danfoss RAS-C2 ive got 8mm microbore pipe but the exsiting ones have been fitted with 15mm trv with reducers would it be ok to use the 15mm danfoss ras c2 and keep the reducer to save cutting the olives or would it be better to fit the 8/10mm danfoss ras c2 any help much appreciated

It will depend on how deep the reducer goes into the new valve or the compression ring will not seat in properly. I've met this problem before and ended up making a small tight hemp gromet to compensate as the ring would not budge due to previous overtightening. Rather than struggle, why not go for the correct smaller valve. and save yourself a headache.

Thanks for the reply i will do that just use a hacksaw to cut the olives off would it affect the performance or anything if I did use the 15mm ones with the reducer

Careful well controlled cutting with a junior saw will not affect anything and nor will a reduced 15mm valve. It that was me I'd also use a smear of a good jointing compound just to ensure a good seal against leaking.

Thanks for the reply and help smear the jointing compound around the threads and over the olive

Yes, just on the area around where the olive will compress and not around the end of the pipe opening.
