Fisher® 1079 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® 1079 manual actuator is a declutchable actuator for manual operation of keyed or square shaft control valves and equipment that use a 1032 power actuator. The 1079 manual actuator mounts directly on the 1032 actuator and 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.

Direct Attachment to the Power Actuator--Direct mounting to the actuator housing simplifies installation and eliminates the need for yokes and other brackets.
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.
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.
