Product benefits

Special Mechanical Design

  • BC has specially designed a quarter-turn actuator dedicated to fail safe applications and with self-locking gears
  • Fast and shock-free operation, several speeds available

Top level reliability

  • No need for external power supply: the FQ works with an automatic spring-return
  • No resetting of the spring is required after emergency operation: failsafe function is continuously available
  • Full electrical priority even in case of manual operation: a lever for manual operation stops the failsafe function of the actuator but not the actuator operation. Moreover, manual operation can be inhibited with a padlock
  • Maintenance-free product: lubricated for product lifetime, no periodic check-up or maintenance to perform
  • Vibration proof cam-block system

Modular design adaptable to specific applications

  • Explosion proof versions: ATEX & NEMA 7
  • Low temperature version: -40°C
  • Separated control box available for advanced integrated control functions and fieldbus communication
  • Suitable for Modulating applications
    (BC Class III complying with EN15714-2 Class C)
