Notes
Safety
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
● Observe national provisions and comply with the appropriate safety regulations.
Engineering
Mounting location
Preferably mount the valves at the return, as the temperature is lower there and the strain on
the stem sealing gland is lower.
Dirt trap
Mount a dirt filter or dirt trap before the valve to ensure the proper functioning and long
service life of the valve. 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 prepressure.
Mounting
Mounting positions
Indoors Outdoors
Mounting positions apply to both 2- and 3-port valves.
