6.3.1 YOKE: Removal/Installation (Fig. 15)
Unbolt the yoke clamp bolting (204 & 233) and remove the yoke clamp (012). (It is advisable to thread the yoke clamp
back together to prevent losing the parts.) The yoke (011) is now free to be lifted directly from the valve, if the
actuator and yoke sleeve have been removed. If the actuator is in place, thread the yoke from the stem by turning the
handwheel or rotating the yoke. Assembly is the reverse of the above procedure.
NOTE: If the valve is to be completely disassembled, unseat the disc slightly before removing the yoke and actuator.
