ATEX certification for pneumatic actuators for ball valves

[Jaivishnu]

Hi , I would like to know , if ATEX certification is required for pneumatic actuators for ball valves since these are mechanical items and no electrical circuit is involved. These actuators are for zone 1/0 hazardous areas

Yes if you've got solenoid valves that control the flow of air. They tend to be electric powered.

Also position switches?



Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Atex certified pneumatic actuators are available. The need for Atex certification depends upon where the actuator is being used.

ATEX is also for mechanical parts. Generally speaking zone 2 and 1 are not that different and zone 0 are much more expensive - but that general not necessary for actuators.
