Actuators ensure automatic opening, closing, and flow regulation of operational substances in HVAC systems and other networks. Actuators with a fail-safe function feature a safety mechanism that ensures, in the event of a power interruption, the safety spring returns the actuator to its default position. This position is adjustable, and thanks to the high variability of actuator control, its position is arbitrary. The use of actuators with a fail-safe function is thus possible even in applications where a high degree of system security and functionality is required.
Actuators with a fail-safe function also allow for manual control and adjustment of the working angle using mechanical stops. Their installation into the system is straightforward.
