Rotary Damper Drives & Actuators

Beck damper drives and valve actuators are capable of continuous modulation and precision control without thermal duty-cycle or motor burnout concerns. Beck damper drives and actuators are specifically designed for harsh indoor and outdoor industrial environments and perform consistently over time. Group 11 damper drives and rotary actuators eliminate the performance problems typical of pneumatic and conventional electric actuators and are virtually maintenance-free.
