Fisher® 1080 manual actuator

Product Description

Fisher^® manual handwheel actuators are used in applications that require a throttling type of control valve that can be manually operated and set. Capable of giving precise manual throttling control, these actuators can be used on nearly all standard globe-style or angle-style valve body assemblies. A travel indicator on the actuator yoke can provide a visual indication of valve plug position.

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.

Easy to Install and Maintain—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.
Easy to Operate—Regardless of the valve plug action, counterclockwise rotation of the handwheel always opens the valve. In size 40 and larger, two ball bearings are used in the handwheel assembly to facilitate rotation. A spring loaded ball detent in the handwheel prevents it from rotating due to vibration.
Accurate Valve Plug Positioning—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 furnished with a Tejax Model A35 valve position indicator. This indicator enables you to turn the handwheel to the desired position without guesswork. The dial on the indicator is divided into turns and fractions of turns so that you can return to a predetermined valve setting quickly and easily.
