L.
With the yoke assembled to the valve in the required orientation,
place spring barrel (38) on desired yoke location and secure
with capscrews (36) and lockwashers (37), and tighten firmly.
M.
Screw in handwheel powerscrew assembly into the
powerscrew hole of the yoke which is on the opposite side
of the spring diaphragm actuator.
Note: Handwheel action is always the same as air action
and opposes the spring.
N.
Replace handwheel washer (51) and Truarc ring (50) and back
off handwheel so the powerscrew will not interfere with the
operation of the lever.
O.
Replace handwheel thread plug (48).
Note: If the valve is equipped with the optional limit stop
(77) instead of the thread plug, it must now be installed, but
ensure it is backed off as not to interfere with the operation
of the lever at this time.
P.
Proceed to Section 11, on Actuator Stem Adjustment.
14. Manual Actuator Option
The manual type actuator is designed to close the valve by
rotating the handwheel in a clockwise direction. Anti-rotation
of the handwheel is obtained through a detente device located
between handwheel (53) and retainer (87).
14.1 Disassembly Procedure
The disassembly procedure for manual actuator is similar to
the procedure for spring diaphragm actuator see Section 8.1.
14.2 Maintenance
Routine maintenance of the manual actuator requires that a
suitable lubricant be periodically applied to the handwheel
powerscrew.
Bearings may require replacement due to service conditions
or corrosion.
The replacement of the handwheel detent mechanism
should be required.
14.3 Reassembly Procedure
There is no specific adjustment for the reassembly of manual
actuator. For details see Figure 21.
