Ambient temperature
3)
SAN
–20 °C to +80 °C during regular operation
SARN
–20 °C to +60 °C during regular operation
under DBE conditions up to +120 °C for a short period (up to 30 min. max)
The max. available torque under DBE conditions (see technical data sheets SAN/SARN),
must be considered when sizing multi-turn actuator to valve.
