Actuators without fail-safe function

Actuators ensure automatic opening, closing, and flow regulation of operational substances in HVAC and other systems. Actuators without a fail-safe function lack a method of securing in case of a fault and do not reset to the initial position in the event of a power failure. This can lead to undesirable movement or system state, hence actuators without a fail-safe function are used in applications where high safety is not required. Actuators without a fail-safe function allow manual control and in normal operation are protected against overload and over-rotation. Their installation into the system is straightforward.
