FAQ
Is this InMax suitable for ATEX areas?
Yes, therefore the actuator complies with the requirements for hazardous explosive zones.
What does the Ex safety circuit do?
This means the actuator shuts down safely in the event of faults; thereby minimizing risks.
Which control do I need?
Compared with on/off, modulating control (0–10 V/4–20 mA) provides more precise regulation.
When should I choose spring return?
In the event of a power failure, the valve automatically returns to a safe position; thereby increasing operational reliability.
Does this fit into my system?
Yes, moreover it connects to common HVAC and process control systems.
