The Fisher® 1080 manual actuator is a Declutchable Actuator for manual operation of A41 double D shaft control valves that use a 1035/El-O-Matic power actuator. The 1080 manual actuator mounts directly on the 1035 actuator. It can be engaged to allow manual operation of the valve when the power actuator is not in use or disengaged to allow automatic operation of the valve by the power actuator.

Features & Benefits
Direct Attachment to the Power Actuator— Direct mounting to the actuator housing simplifies installation and eliminates the need for additional mounting parts.
Engage Manual Actuator At Any Point of Rotation— A lever-operated eccentric bearing support on the input shaft allows engagement of the worm gear with the sector at any point of rotation.
Simplified Selection— Each size of the Type 1080 corresponds to the capabilities of a size of the Type 1035. So you need only calculate the size of the Type 1035, when ordering both a Type 1035 and Type 1080.
Positive Operation— The disengagement lever is held in both the engaged and disengaged positions by a spring-loaded pin, which must be released before the lever can be moved. This reduces the possibility of inadvertent or accidental operation. In addition, stop-pins at the fully engaged and fully disengaged positions provide positive limits for lever travel.
