Engineering notes
Preferably mount the valves at the return, as the temperature is lower there and
the strain on the stem sealing gland is lower.
Mount a dirt filter or dirt trap before the valve to ensure proper functioning, and a
long service life of the valve.
Remove dirt, welding beads, etc. from the valves and pipes.
Cavitation can be avoided by limiting the pressure differential across the valve
depending on the medium temperature and the prepressure.
