In soldering a copper ball valve to a copper pipe, replacing stuck gate valves, I understand I mustn't overheat the valve, so as not to damage the seals, but what sort of flux is best? I know acid flux should not be used, but is flux using ammonium chloride or zinc chloride acceptable, or might they cause corrosion in the long run? I won't really be able to flush the pipes very well, this is part of a hydronic heating system. I suppose resin flux would be acceptable in that it would not cause corrosion, but can one be reasonably sure it will prepare the surfaces well enough for a good joint?
The books and articles one finds don't seem to really address this issue. I'm familiar with soldering electronics, but not yet with soldering pipes.
thanks very much for your help.
