Fisher Manual Actuators
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.
Fisher® 1077 manual-only handwheel actuator is for use with rotary-shaft valves such as the 9500 butterfly valve; 8532, 8560, and 8580 eccentric disc valves; V150, V200 and V300 Vee-Ball™ valves; V250 valves; and CV500 and V500 valves. In this actuator, torque is transmitted from the handwheel through the handwheel input shaft to a worm and drive sleeve gear (sector) with splined bore. The worm and drive sleeve gear multiply the torque and transmit it to a splined valve shaft or splined stub shaft. The size 10-KE:6 actuator additionally has a spur gear reduction drive for increased torque capability.
Easy to Install and Maintain—Splined valve shaft mates directly with the drive gear sleeve, reducing the number of parts required and simplifying installation and maintenance.
Easy to Operate—Handwheel rotation direction required to open the valve disc or ball is marked on the handwheel; the rotation indicator is marked in bold print at the open and closed positions and with bold incremental lines to indicate the valve disc or ball position.
Consistency of Operation—When installed according to instructions, clockwise handwheel rotation clos
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.
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 dete
Fisher® 1078 manual actuators are declutchable actuators for manual operation of control valves and equipment that use power actuators. The 1078 manual actuator mounts directly to Fisher 1051 sizes 33, 40, and 60; 1052 sizes 33, 40, 60, and 70; 1061 sizes 30, 40, 60, 68, 80, and 100; and to all sizes of 1066 and 1066SR actuators.
For 1051 size 33, 1052 size 33, 1066, and 1066SR actuators, coupling to the power actuator is via a flatted shaft installed in the lever or hub. The dimensions of these shafts are the same as those used with H mounting adaptations. The stub shaft fits into a square broach in the manual actuator sector, and spacers secure the shaft in the appropriate position.
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. Because the travel indicator components are mounted on a through shaft, accurate travel indication is maintained during manual actuator disengagement
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.
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.
Direct Attachment to the Power Actuator— Direct mounting to the actuator housing simplifies installation and eliminates the need for additional mounting parts.
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.
Simplified Selection— Each size of the Type 1080 corresponds to the capabilities of a size of the Type 1035. So you need only calculate the size of the Type 1035, when ordering both a Type 1035 and Type 1080.
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 inadve
Fisher® M Series handwheel gear actuators are totally enclosed, weatherproof, worm gear actuators for reliable manual operation with Fisher A11, A31A and A41 High Performance Butterfly Valves. The M actuator consists of a body housing, cover, worm gear, input shaft, and handwheel. The housing is grease packed.
Long Service Life—Rugged construction provides stability and corrosion resistance. The unit is totally enclosed for weatherproof operation.
Accurate Valve Disc Positioning—Two adjustable stops are located in the housing for correct adjustment of disc position. The actuator is inherently self-locking, unless subjected to high vibration.
Overtravel Capability—Provides for five degrees of overtravel in both directions for precise positioning of the valve disc.
