Selection of the drain valve behind the radiator
Thread Content
With steam heating at 3 bar/170°C in the factory building, is it necessary to install a drain valve behind each group of radiators? Is it set on the main pipe or at each segment?
It is best to install one on each radiator, or install a steam trap in several sections. If there is a certain height difference in the pipes, it is also possible to install only one on the main pipe (the effect is not very good)
If it can be packaged separately, do so; moreover, it’s best to use better-quality steam traps, as some steam traps are completely ineffective and cause serious waste of steam
It is usually packaged in slices. . . . . . . . . . . . . . .

A steam trap should be installed at the lowest point of the pipeline, in order to prevent water hammer caused by an excess amount of cooling water, as well as to avoid pipe freezing and cracking after the supply of gas is interrupted (this often happens in northern regions)
