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)
