3.1. Identification of valves for use in ATEX environment
ATEX identification:
- Equipment group II
- Equipment category
- Explosion subcategroy IIB
Ambient temperature for the operation
0 °C ≤ T ≤ 40 °C
amb
- Temperature classes TX (according to table 3.2)
3.2. Temperature classes and permissible temperatures
Media temperature
Safety addition
Temperature class
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!
