5.3.2 Spring kit - How to fit:
Note:
Items
9
and
28
do not apply to the PN9400 actuator.
-
Remove actuator from valve as described in Section 5.1.
-
Lubricate the threads of the three long hex. head screws with a PTFE based grease
before releasing the tension in the springs.
-
Loosen and remove the short housing screws and nuts (
22
,
23
and
24
).
-
Holding each nut with a spanner, rotate the three long hex. head screws a few turns at
a time. Remove the screws and upper housing (
2
).
Note 1:
On certain spring ranges 3 off longer housing screws are fitted to safely allow
spring decompression (
23
). These should be removed last after all other bolts are
removed and should be loosened evenly to prevent distortion of the housing.
-
Taking care not to damage the 'O' ring (
9
) fitted between the diaphragm support plate
(
3
) and spacer (
8
), remove the washer (
28
) and the diaphragm (
4
).
-
Using a spanner to hold the actuator spindle (
6
), loosen and withdraw the bolt (
21
).
Remove the washer (
7
), the diaphragm (
4
) and the diaphragm plate (
3
). Remove the
springs (
5
) taking note of their location.
-
Replace the new springs (
5
) locating them in the same position as the previous set.
-
Refit all other items in reverse order. Using a spanner, to hold the actuator spindle so
that the diaphragm sits evenly in the lower housing, refit the top housing (
2
) and securing
nuts and screws (
22
,
23
and
24
).
Note 2:
Tighten the housing securing bolts evenly to avoid distortion. 3 off longer
housing screws (
23
) are provided on some spring ranges to cater for longer springs.
If supplied, these should be positioned 120
°
apart and tightened evenly prior to fitting
the remaining screws.
Refer to Table 1, for the recommended tightening torques.
