Explosion-proof actuators SQEx and SQREx
Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as ignition source.
Their constructive measures prevent the occurrence of ignition sparks or hot surfaces.Certification is performed in close collaboration with national and international certification bodies.
Design features SQEx:
- Torque rang from 50 Nm to 2,400 Nm
- Swing angles from 75° to 105°
- Operating time ranges for 90° from 4 s to 100 s
- Limit and torque seating 3-ph AC motors
- Handwheel for manual operation
- Mechanical Position indicator
Design features SQREx:
- Torque rang from 50 Nm to 2,400 Nm
- Modulating torque from 75 Nm to 1,200 Nm
- Max. number of starts 1,500 c/h
- Swing angles from 75° to 105°
- Operating time ranges for 90° from 8 s to 100 s
- Limit and torque seating
- 3-ph AC motors
- Handwheel for manual operation
- Mechanical
- Position indicator
