Description
The 1077 manual-only handwheel actuator (figure 1) is used with rotary-shaft valves such as the Fisher 9500 butterfly
valve, 8532, 8560, and 8580 eccentric disc valves, V150, V200 and V300 Vee-Ball™ valves, V250 valves, and CV500
and V500 eccentric plug valves. In the 1077 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.
Specifications
1077 actuator specifications are given in table 1. Some specifications for a given actuator as it comes from the factory
are stamped on a metal nameplate attached to the actuator mounting yoke (key 7, figure 6).
