Description
The Type 1077 manual-only handwheel actuator
(figure 1) is used with rotary-shaft valves such as the
9500 butterfly valve, Type 8532 and 8560 eccentric
disc
valves, Design V150, V200 and V300 Vee-Ball
R
valves, Design V250 valves, and Design CV500 and
V500 eccentric plug valves. In the Type 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
Type 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).
