Fisher Manual Actuators Fisher 1077 manual-only handwheel actuator

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 closes the valve in all applications.
• Accurate Valve Disc or Ball Positioning—Travel stops can be adjusted and locked in place to provide accurate disc or ball positioning at closed (0-degree) and open (90-degree) positions. Travel stops for 60-degree operation may be used to establish a disc or ball closing stop at any angle between 0 and 30 degrees and/or to establish a disc or ball opening stop at any angle between 60 and 90 degrees. This option is available on sizes 2-KE and 7-KE as a set screw change. For sizes 0-KE, 6-KE, 9-KE, and 10-KE:6, a different actuator is required when changing from 90-degree to 60-degree ball rotation.
