Saftety addition
Temperature class
Under standard operating conditions the highest surface
temperature will be comparably as high as the temperature of the
medium plus a safety addition for local temperature increases. The
valve must be completely free to the environment in order to provide
for sufficient heat release.
All data (temperature classes) refer to an ambient temperature
of 0°C to 40°C. If the ambient temperature is above 40°C, the
temperature difference must be adjusted. In all cases, contact your
responsible SPX FLOW representative!
