Method 2: Points G-2 / H-2 / I-2 / J-2 / K-2
G-2.
Apply coating of Neoprene glue (or similar) on the bead and
on the inner face of the diaphragm (40), on the piston (43)
and in the spring barrel lip (38).
Note: The inner face of the diaphragm in contact with
the piston is marked with the inscription "piston side";
be careful to keep coating of the Neoprene with limits
corresponding to the flat part of the piston (Figure 7-
Method 2, Step A).
H-2.
Center and adhere the diaphragm (40) on the piston (43)
(Figure 7- Method 2, Step A).
I-2.
Roll the diaphragm (40) carefully inside the spring barrel
(38) until the bead engages the spring barrel groove (38).
Press lightly and evenly the bead so as to get with the two
Neoprene-coated part stuck together. Check there is no
twisting of diaphragm inside the spring barrel (Figure 7-
Method 2, Step B).
J-2.
Adjust diaphragm case (42) to the spring barrel (38) after
checking that air connection is on the correct side and the
threaded holes of diaphragm case (42) and the holes of the
spring barrel (38) line up.
Note: Tapped air connection should be in line with the
vent hole in spring barrel (38).
K-2.
Clamp the bead of the diaphragm (40) between lips of
diaphragm case (42) and spring barrel (Figure 7- Method 2,
Step C).
For next step, go to point L.
L.
Ensure that the diaphragm case (42) is evenly seated on the
spring barrel (38), insert the four capscrews (41) and tighten
evenly.
I-1.
Center and adhere diaphragm (40) to the top of the piston
(43) (see Figure 7-Method 1, Step A).
J-1.
Roll the diaphragm (40) inside the spring barrel (38) until
the diaphragm is partially engaged in the spring barrel (see
Figure 7-Method 1, Step B).
Ensure that the capscrew holes in the diaphragm case
and spring barrel are aligned to prevent twisting of
the diaphragm in aligning the holes. The diaphragm
case (42) is normally assembled with the air inlet port
placed on the bottom side of the actuator. Depending
on the desired location, it can be placed in any desired
position around the spring barrel which allows the
capscrew holes to line up. However, the drain hole
in the spring barrel must always be facing down to
allow for draining of any moisture which may enter
the spring barrel cylinder (38). If the valve is equipped
with the optional purge line, that line is inserted into
the drain hole.
K-1.
Place the bead of the diaphragm (40) over the diaphragm
case lip (42) and carefully slide the diaphragm case (42)
down over the piston (43) until it seats on spring barrel (38).
(see Figure 7-Method 1, Step C).
For next step, go to Point L.
