Under standard operating conditions the highest surface
temperature will be comparably as high as the temperature of the
medium (product and cleaning liquid) 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!
