Danfos HSV3 valves

[handyspanner]

Hi,

First post of many, I am sure now that I have found this site. It looks very supportive.

Happy New Year (belated now) to all.

I have a problem (leaking gland) with my Danfoss HSV3 valve for my CH system. I have purchased a replacement (off the internet from the UK) and when it arrived it is an HSV3B and not an HSV3. Different body and different Valve (plug) in that it is a paddle instead of a shoe (according to the Danfoss info).

My question, having looked through the Danfoss literature, there is no specific guidance I can see. So what is the difference between the two and could I use this different valve (HSV3B in the place of the old HSV3).

Many thanks,

HS

Yes, straight swap.

I'd replace with Honeywell as I think it's motor open, and spring close. I may be wrong though.

Mr W,

Thanks for the reply. Do you know what is the difference between the two valves. I would like to understand why the two are different and if it is a straight swap why one is a padddle and one a shoe.

Thanks,

HS
