InstallatIon and MaIntenance InstructIons
2.3 Main valve assembly
refer to Figure 2 for parts description and
location.
2.3.1
Clean all components and inspect for any
damage. replace components if damaged.
2.3.2
Lubricate nozzle (3) threads and nozzle-
to-body mating surfaces with pure Nickel
'Never-Seez' or equivalent and then screw into
the body (1) and tighten with the appropriate
nozzle wrench.
2.3.3
install the retaining clip (9) onto the groove
in the disc insert (8). Lubricate disc insert and
disc holder (4) mating bearing surfaces with
pure Nickel 'Never-Seez' or equivalent and
then place the disc insert into the disc holder
and push on the disc insert until it snaps into
the disc holder.
2.3.4
Slide the guide (5) over the disc holder.
2.3.5
install guide-disc holder sub-assembly
(2.3.4 above) into body using the stainless steel
lower guide gasket (10) and organic fiber upper
guide gasket (18).
note:
Take care when installing the guide-disc
holder sub-assembly to avoid damaging the
sealing surfaces of the disc or nozzle
2.3.6
A soft goods kit will have a new liner
O-ring, piston O-ring, upper and lower guide
gasket, wedge ring and body drain fitting
gasket. if the original wedge ring and lower
guide gasket are not damaged, they can be
cleaned and reused.
2.3.7
Place the wedge ring (13) on the upper end
of the piston (6). Coat piston O-ring (12) with
Dow Corning Molykote 33 and then slide it in
place above the wedge ring.
2.3.8
Lubricate disc holder-piston bearing
surface with pure Nickel 'Never-Seez' or
equivalent.
2.3.9
Slide piston sub-assembly (2.3.7 above)
inside the liner (7). Then place piston-liner
sub-assembly onto disc holder and upper guide
gasket.
2.3.10
Lubricate cap stud (15) threads with pure
Nickel “Never-Seez” or equivalent and then
install into the body (1) until they tighten against
bottom of the body threaded hole. There should
be at least two threads exposed above the nut
when the valve is fully assembled. Wipe off
excess lubricant.
2.3.11
Coat liner O-ring (11) with Dow Corning
Molykote 33 and then slide it in place on the
liner.
2.3.12
Slide cap (2) over the liner and studs until
it rests on the upper guide gasket.
2.3.13
Place bracket (16) onto cap studs at
opposite side of the main valve outlet.
2.3.14
With the cap and bracket in place,
lubricate cap stud threads, nut threads and
nut face with pure Nickel 'Never-Seez' or
equivalent. Then install nuts on the studs
finger-tight. Verify that at least 2 stud threads
are exposed above the nut. readjust stud height
as required to achieve thread protrusion.

2.3.15
Tighten the nuts (14) in the sequence
shown in Figure 6 to approximately one-half
the minimum torque value shown in Table 5.
repeat the same sequence of tightening to the
minimum torque value shown in Table 5. Then,
starting with the number 1 nut, tighten each
nut in order in a clockwise or counterclockwise
direction to a value no greater than the
maximum torque value shown in Table 5. Wipe
off excess lubricant.
2.3.16
Lubricate body drain fitting (17) threads
with pure Nickel 'Never-Seez' or equivalent.
install one gasket (22) onto the body drain
fitting and then tighten the fitting into the body.
The drain fitting must be oriented so the drain
port will point downwards and the drain port
piping will clear the inlet flange. if necessary,
use a second gasket to orient the drain port
properly while also providing a tight seal.
2.3.17
if applicable, lubricate body plug threads
with pure Nickel 'Never-Seez' or equivalent.
install the gasket (22) onto the plug and then
screw the plug into the body.
