now be installed, but insure 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.
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 § 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.
