3.5 Limits for application
The actuators are designed to be used in ambient temperatures between -30°C and +80°C. The temperature
limit is due to the material of the membranes and seals.
The pressure springs as well as the membranes are designed for 2 million strokes.
The maximum operating pressure of the actuators is 6.0 bar.

Danger !
Before beginning any work, please observe:
• Switch electrical components voltage-free and secure against unintentional restart!
• Work properly and following the EC safety regulations as well as the warnings and
information in this operating manual.
• Ensure that the pipe section where the valve is located is pressure-free.
• Allow the valve to cool down to about room temperature.
