Categories or Zones
The various ATEX regulations boil down to three different areas:
||Also called Zone 2 for Gas or Zone 22 for Dust. This is an area where an explosive atmosphere is unlikely to occur. We can supply Valves certified to this area.|
||Also called Zone 1 for Gas or Zone 21 for Dust. This is an area where an explosive atmosphere is likely to occur. We can supply Valves certified to this area.|
||Also called Zone 0 for Gas or Zone 20 for Dust. This is an area where an explosive atmosphere is highly likely to occur. We cannot supply Valves certified to this area.|
More applicable to solenoid valves and limit switches fitted to the valves rather than the Knife Valves themselves these indicate the maximum surface temperature that the equipment can reach and therefore restricts the equipment to which ignition temperatures it can work with.
We can supply Knife valves Certified to any of the Temperature Classes. For reference, here are the temperatures:
T1 450 °C
T2 300 °C
T3 200 °C
T4 135 °C
T5 100 °C
T6 85 °C
We can supply ATEX Certified Knife Gate Valves fitted with double acting and spring return pneumatic actuators.
We can supply ATEX Certified Knife Gate Valves actuated by Handwheel, Lever or Square top.
It is our understanding that manually operated valves are excluded from the scope of ATEX Directive 94/9/EC but we do have customers insisting on ATEX Certificates for these.
