Fisher™ 1080 Declutchable Manual Actuator
The Fisher 1080 manual actuator is a declutchable actuator for manual operation of control valves that use a 1035/El-O-Matic™ power actuator. The 1080 actuator mounts directly on the 1035 actuator and can be engaged to allow for manual operation of the valve when the power actuator is not in use or disengaged.
The Fisher™ 1080 Declutchable Manual Actuator, designed by Emerson, is a robust and reliable handwheel actuator engineered to provide manual override control for rotary valves and other actuators. It enables operators to manually position valves during power loss, system failure, or maintenance activities—ensuring continuous process control and operational safety.
This declutchable design allows the actuator to be engaged or disengaged from the valve drive mechanism without removing power or pressure from the system. The Fisher 1080 provides smooth and precise manual control, offering a direct mechanical link to the valve stem for accurate positioning.
Built from durable, corrosion-resistant materials, the Fisher 1080 actuator is designed for harsh industrial environments, including oil and gas, refining, chemical, and power generation. Its compact, field-serviceable design makes it ideal for valve automation systems where manual intervention is critical for safety and reliability

Feature of Fisher™ 1080 Declutchable Manual Actuator
- Direct mounting to the actuator housing simplifies installation and eliminates the need for additional mounting parts.
- A lever-operated eccentric bearing support on the input shaft allows engagement of the worm gear with the sector at any point of rotation.
- Each size of the 1080 actuator corresponds to the capabilities of a size of the 1035. So you need only calculate the size of the 1035, when ordering both a 1035 and 1080.
- 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
