bolt circle in the mounting plate adaptor (key 56)
must be spaced (aligned) an equal distance over
the downstream control line connection. Install cap
screws and hex nuts (keys 35 and 36) with a torque
of 20 to 30 ft-lbs / 27 to 41 N•m.
7. Place the balancing plate washer (key 23),

(key 22), be certain the side marked
PISTON SIDE is facing the spring case.
Carefully tuck the slack diaphragm
material into the space between the
diaphragm plate (key 21) and lower
casing (key 7) until the diaphragm
ts smoothly over the diaphragm
plate without wrinkles and the bead
ts snugly and evenly in the groove
provided in the lower casing. This can
be done with a small screw screwdriver,
but be careful not to puncture the
diaphragm (see Figure 6).

to the sealing washer (key 17) and carefully slide
over the threaded end of the stem (key 18).

(key 29), washer (key 30) and hex nut (key 31)
onto the stem. The registration disk (key 29) is

positioned correctly on the stem (key 18). Tighten
the hex nut (key 31) using the 1/2 in. / 13 mm
wrench ats on the stem sleeve.

connection (key 51) so it is pointing directly
over the body outlet.
14. Screw the studs (key 33) into the body (key 1).
Install and tighten the hex nuts (key 34) to
20 to 35 ft-lbs / 27 to 47 N•m of torque.
