Function / performance characteristics

The rotary drives are used in technical building services, chemistry, pharmaceuticals, industry and offshore systems.

All rotary drives can be parameterised and adjusted locally without the use of additional electronic equipment. The motor run time and potentially the spring return periods can be selected locally.

The modular design enables upgrades with adjustable auxiliary switches and other accessories.

All rotary drives are distinguished by the following performance characteristics:

• 100 % blocking resistance
• Drives made from stainless steel and sintered steel
• Integrated heating to −40 °C ambient temperature
• Integrated safety temperature limiter
• Concealed controls for parameter setting (button, LED, switch)
• Preparation for upgrades and adjustable external auxiliary switches
• Comprehensive accessories concept

Special versions (label -F) are equipped with integrated spring-return function to implement safety settings.
