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
