Fisher® 1080 Declutchable Manual Actuator

nnnn

The Fisher 1080 manual actuator is a Declutchable

nnnn

Actuator for manual operation of A41 double D shaft

nnnn

control valves that use a 1035/El-O-Matic power

nnnn

actuator. As shown in the following figure, the 1080

nnnn

manual actuator mounts directly on the 1035

nnnn

actuator. It can be engaged to allow manual operation

nnnn

of the valve when the power actuator is not in use or

nnnn

disengaged to allow automatic operation of the valve

nnnn

by the power actuator.

nnnn

Features

nnnn

Direct Attachment to the Power Actuator— Direct

nnnn

mounting to the actuator housing simplifies

nnnn

installation and eliminates the need for additional

nnnn

mounting parts.

nnnn

Engage Manual Actuator At Any Point of Rotation—

nnnn

A lever-operated eccentric bearing support on the

nnnn

input shaft allows engagement of the worm gear

nnnn

with the sector at any point of rotation.

nnnn

Simplified Selection— Each size of the 1080

nnnn

corresponds to the capabilities of a size of the 1035.

nnnn

So you need only calculate the size of the 1035,

nnnn

when ordering both a 1035 and 1080 (see table 1).

nnnn

Fisher 1080 Manual Actuator Mounted on a

nnnn

1035/EI-O-Matic Actuator

nnnn

Positive Operation— The disengagement lever is

nnnn

held in both the engaged and disengaged positions

nnnn

by a spring-loaded pin, which must be released

nnnn

before the lever can be moved. This reduces the

nnnn

possibility of inadvertent or accidental operation. In

nnnn

addition, stop-pins at the fully engaged and fully

nnnn

disengaged positions provide positive limits for

nnnn

lever travel.
