Maintenance of the actuator  

packing box

The  actuator  packing  box  requires  minimum  maintenance. 

The PTFE - Kevlar packing rings have a square section and 

a  skive  cut  allowing  easy  replacement.  The  packing  may  be 

added to or completely replaced without disassembling either 

the actuator or regulator body S/A. Be sure to tighten packing 

nut  (20)  lightly.  Overtightening  will  cause  excessive  friction 

resulting in sluggish performance.

 ●  Recommended spare parts
 *  Complete subassembly includes: Plug-stem (183), Retaining ring (182), Seat ring (3e) and Spacer (3f). (See figure 2)
 +  Non-existent on Cv 3.8
