TIGRON TR-M SIL

The TIGRON in SIL version is a powerful, explosion-proof actuator for highest safety requirements up to SIL 3. It allows flexible configuration and even provides solutions for very complex demands in safety-related applications.

Up to four different safety functions can be configured and their priority freely defined.

Further parameters such as type of seating, tripping torque and overload protection of the safety function can also be set in compliance with the customer’s needs. A timer function protects against pressure surges within the pipeline. The safety functions are controlled and monitored by a safety-related software.

Torque range

10 Nm to 1000 Nm

Explosion-proof for open-close and modulating duty

Service conditions

  • Wide temperature range
  • Highest enclosure protection
  • High quality corrosion protection

Functional safety - SIL
