5.5 Valve and body HON HSVS
(see figures 7a and 7b)
The following parts should be replaced in this component during maintenance:
 2x O-ring retainer set 21 (no seal, must be replaced during fitting, however)
 O-ring rod 22
 O-ring guide 23
 4x socket screw 24
 O-ring cover 26
 O-ring valve 30
 12x socket screw 31
 O-ring valve seat 32
 O-ring guide 39
 O-ring 40 (only fig. 7b)
 O-ring guide of valve stem guide 41
 O-ring guide of valve stem seat 42
 O-ring bottom cover 48
 Filler block 01 (no seal, must be replaced during fitting)
Work as follows to replace these parts:
 The valve should be closed.
 Disconnect impulse line of the pressure converter (pos. 21 in fig. 6).
 Remove protective cap 25 (see figure 7a).
 Unscrew screw connection 47 and dismount the complete SVC086.
 Unscrew screw connections 38, 40 (figure 7a) and dismount the complete second
stage.
 Detach connection rod 04 (figure 7a) from top coupling section 07a.
 Unscrew screw couplings 38, 53, 28.
 Lift cover 09 from body 16 by load frame 37 provided for this purpose (not shown
in figure 7a). To simplify detachment of the cover 09 from body 16 you may use
lock screws 55 (having released plug 56).
 When you have used the lock screws 55, you should tighten them again and fit
plug 56.
 Valve 12 is now underneath cover 09.
 Place cover 09 with valve 12 on a surface which guarantees that valve rod below
19 sticks through the surface and that valve 12 with cover 09 lies horizontally
(when putting it down on the surface, cover 09 slides over the valve rod top 14).
 Loosen the connections between coupling top 07a and coupling bottom 07b and
disconnect coupling top.
 Disconnect retainer set 02 from connection rod 04.
 Replace O-ring retainer set 21.
 Slowly lift cover 09 with guide of valve rod top 08 by the load frame 37 provided for
this purpose (not shown in figure 7a) and lift over connection rod 04.
 Place cover 09 on a similar surface as the valve.
 Remove lock ring 40
