Electric Actuator - FQ Range | Bernard Controls

The Electric Actuator - FQ Range by Bernard Controls is a robust and versatile solution designed for fail-safe applications, offering a torque range of 40 to 500 Nm. It features explosion-proof versions compliant with ATEX and NEC500 standards, ensuring safety in hazardous environments. The actuator supports various control types, including electromechanical switches and integrated control boxes like INTEGRAL/POSIGAM. It is classified for On-Off (Class A), Inching/Positioning (Class B), and Modulating (Class III) operations, adhering to EN15714-2 Class C standards. With an IP67 environmental rating, it is suitable for challenging conditions. The actuator includes a fast spring return mechanism with options for clockwise or counterclockwise action. Its special mechanical design ensures self-locking gears and shock-free operation. The FQ Range is maintenance-free, with a vibration-proof cam-block system and modular design adaptable to specific applications, including low-temperature environments and advanced control functions.

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: fail-safe function is continuously available
  • Full electrical priority even in case of manual operation: a lever for manual operation stops the fail-safe 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)
