6.0 DISASSEMBLY
(Continued)
6.1.2 Gear Actuators (continued)
Later model valves (Fig. 11) are supplied with self-contained units that can be separated from the yoke
(011) by removing the actuator capscrews (218). If a stem protector (334) is provided it should be removed.
With the actuator properly supported, it may be raised off the yoke either by turning the handwheel or
rotating the entire unit.
6.1.3 Electric Motor Actuators
Although various types of electric motor actuators (Fig. 12) are supplied, all follow the same pattern for their
removal from the valve. Prior to removal, all power and control wiring should be disconnected from the
actuator. With the stem protector (334) and capscrews (218) removed, and the actuator properly
supported, it can be raised in the same manner as the gear unit.
