8.  Unscrew the threaded bushing (11) to-

gether with the actuator base (6) from 

the valve bonnet (10) using an 24 mm 

open-end wrench.

9.  Press the threaded bushing (11) out of 

the actuator base (6). Replace the slip 
washers (38) with new ones.

10. Pull the actuator/plug stem (14) down 

out of the valve bonnet (10).

11. Pull all the packing parts out of the pack-

ing chamber using a suitable tool. Clean 
the packing chamber thoroughly. Renew 
the packing.

12. Slide the plug/actuator stem into the 

valve bonnet (10).

13. Carefully slide the packing parts over the 

plug/actuator stem into the packing 
chamber using a suitable tool. Keep the 
correct sequence:

 

Spring (21)

 

Washer (44)

 

V-ring packing (22)

14. Place the top slip washer (38) into the 

actuator base.

15. Push the threaded bushing (11) into the 

actuator base (6). Make sure that the 
O-ring (36) is correctly seated in the 
threaded bushing.

16. Place the bottom slip washer (38) on the 

valve bonnet (10).

17. Screw the threaded bushing (11) togeth-

er with the actuator base (6) over the 
plug/actuator stem (14) onto the valve 
bonnet (10).

Tighten the threaded bushing only to the 
point where the actuator base (6) can 
still rotate on the slip washers (38).

18. Screw tight the retaining screw (60) at 

the side to fix the threaded bushing in 

place.

19. Slide the washer (43) onto the plug/ac-

tuator stem (14).

20. Place the spring (20) together with the 

washer (46) onto the actuator base (6).

21. Slide the piston (3) with piston ring (23) 

over the plug/actuator stem (14).

22. Place on the O-ring (33) and washer 

(43).

23. Tighten the nut (49) intended for fasten-

ing the piston, while holding the plug/

actuator stem (14) stationary at the flat

-

tened part with an 8 mm open-end 

wrench.

24. Put on actuator housing (2) and fasten it 

tight onto the actuator base (5) by tight-
ening the screws (47) gradually in a 
crisscross pattern.

25. Replace the body gasket (31). See sec-

tion 7.1.

26. Screw the valve bonnet (10) with actua-

tor onto the body (1). Observe tightening 
torques.
