Fisher™ 1008 Manual Handwheel Actuator
The Fisher 1008 manual handwheel actuator is used in applications that require a throttling type of control valve that can be manually operated and set. This actuator can be used on nearly all standard globe style or angle style control valve body assemblies. No special valve body adaptor is required for use with the 1008 actuator, so that future conversion from manual to automatic control can be accomplished at minimum cost. The 1008 actuator is capable of giving precise manual throttling control. A travel indicator mounted on the actuator yoke provides a visual indication of valve plug position at all times. A dial-type valve plug position indicator is also available as optional equipment.
The Fisher™ 1008 Manual Handwheel Actuator is a robust, manually operated actuator designed for precise and dependable positioning of sliding-stem control valves. Manufactured by Emerson, the 1008 actuator offers smooth, accurate control for both throttling and on/off service, making it ideal for applications where manual operation or mechanical override is required. The 1008 handwheel actuator provides direct mechanical motion to the valve stem, ensuring consistent valve performance without reliance on pneumatic or electric power sources. Its rising-stem design allows for precise stem travel indication, while the self-locking screw mechanism holds the valve securely in the desired position under process pressure. Built from heavy-duty cast iron or steel, the Fisher 1008 is engineered to withstand demanding industrial environments, providing long service life and reliable performance in manual control or emergency override scenarios. It is available in multiple sizes and configurations to suit a wide range of Fisher globe and angle control valves. Ideal for remote installations, power-restricted sites, or backup control systems, the Fisher 1008 combines simplicity, strength, and accuracy—ensuring dependable valve control even under the toughest process conditions.

Feature of Fisher™ 1008 Manual Handwheel Actuator
- For sizes 30, 40, and 50, the yoke is attached to the valve body with a forged steel hammer locknut. For the size 80, the yoke is bolted to the valve body. The handwheel mechanism on all sizes is totally enclosed.
- Regardless of the valve plug action, counterclockwise rotation of the handwheel always opens the valve. A spring-loaded ball detent in the handwheel prevents it from rotating due to vibration.
- The valve stem does not revolve, assuring the same seating surface with each full stroke. Also, the yoke construction ensures that the force required to turn the handwheel cannot be transmitted to the valve body. Sizes 30, 40, and 50 actuators can be fur
