Notes
Engineering
Mounting location
Preferably mount the valves at the return, as the temperature is lower there and the stain on
the steam sealing gland is lower.
Dirt trap
Mount a dirt filter or dirt trap before the valve to ensure proper functioning, and a long service
life of the valves.
Remove dirt, welding beads, etc. from the valves and pipes.
Cavitation
Cavitation can be avoided by limiting the pressure differential across the valve depending on
the medium temperature and the pre-pressure.
Mounting
Mounting position
Mounting positions apply to both 2- and 3-port valves.
