Range of application
AUMA part-turn actuators are designed for the operation of industrial valves, e.g.
butterfly valves and ball valves.
The devices described below are approved for use in the potentially explosive
atmospheres of zones 1, 2, 21, and 22.
If temperatures >40 °C are to be expected at the valve mounting flange or the valve
stem (e.g. due to hot media), please consult AUMA. Temperatures > 40 °C are not
considered with regards to the non-electrical explosion protection.
Other applications require explicit (written) confirmation by the manufacturer.
The following applications are not permitted, e.g.:
●
Industrial trucks according to EN ISO 3691
●
Lifting appliances according to EN 14502
●
Passenger lifts according to DIN 15306 and 15309
●
Service lifts according to EN 81-1/A1
●
Escalators
●
Continuous duty
●
Buried service
●
Continuous submersion (observe enclosure protection)
●
Potentially explosive areas of zones 0 and 20
●
Potentially explosive areas of group I (mining)
●
Radiation exposed areas in nuclear power plants
No liability can be assumed for inappropriate or unintended use.
Observance of these operation instructions is considered as part of the device's
designated use.
Information
These operation instructions are only valid for the "clockwise closing" standard
version, i.e. driven shaft turns clockwise to close the valve.
