2.
For Mark HPX2D and HPAX2:
2.1.
New piston rings will be delivered in one
piece. The piston ring can be broken in
half by scoring and breaking over a hard
surface such as a table edge. The other
recommended method is to break the
ring with the use of a smooth or
taped jawed vise. Install
the new ring in the vise and apply
pressure until the ring becomes an oval.
Continue applying pressure until the ring
on both sides. If just one side snaps
do not try to rip off the other side.
Apply pressure until the second
side
breaks.
2.2.
Remove the protective covering from the
valve plug and stem assembly.
2.3.
Insert the piston rings into the piston ring
grooves matching the broken ends.
3.
For Mark HPX5T and HPAX5:
3.1.
Install for flow-down applications (see
Figure 4, view A), install the ring with the
open side facing the seat ring end of the
valve
plug.
3.2.
Install the back-up ring (key 28) on the
valve plug (key 22) and secure with the
retaining ring (key 27).
4.
Install the valve plug (key 22) in the cage (key 12)
and place the bonnet gasket (key 19) on
the cage.
5.
After lubricating the bonnet stud threads (key 7)
and the faces of the bonnet hex nuts (key 8),
tighten the hex nuts finger tight.
Note:
If pre-lubricated hex nuts are used, lubrication will
not be necessary. Jordan Valve recommends Never-Seez
Pure Nickel special lubricant or equivalent for lubricating.
6.
Tighten the bolts in a three-step process:
6.1.
Begin by tightening the bolts to 1/4
of the specified normal torque (Table
2) using the standard crisscross
bolting
pattern.
6.2.
Using the same method tighten the
bolts to an additional 1/4 of
the specified normal torque value
(Table
2)
6.3.
Continue tightening bolts to the
nominal torque value from Table 2.
7.
Test the nuts by applying the final torque
value. If the nuts still rotate, tighten all the
nuts again.
8.
Install the packing and the packing box
components following the instructions from
“Replacing Packing”.
9.
Using the actuator instructions mount the
actuator.
10.
If leakage occurs in the packing when the
valve is put back into service, it may be nec-
essary to retighten the packing flange nuts.
