Abstract: A valve (1), which has heat-sensitive parts, has at least one connecting tube (3, 4, 5) to which a pipe is arranged to be soldered using local heating. The connecting tube (3, 4, 5) consists of a material of such low thermal conductivity that the heat-sensitive parts remain below the limit temperature as the heat required for soldering is applied. No cooling measures are therefore needed while the pipe is being joined by soldering.
