WHEN ASSEMBLING THE ACTUATOR,
THE UPPER CASING AND ADAPTOR
SHOULD BE POSITIONED SO THAT TWO
HOLES IN THE 5.25 in. / 133 mm BOLT HOLE
CIRCLE ARE EQUALLY SPACED OVER THE
CONTROL CONNECTION

Figure 9. Diaphragm Casing Assembly
1. With the Type 133HP completely disassembled,
start the reassembly by applying Multi-Purpose
PTFE lubricant or an equivalent to the stem threads
(key 18) and diaphragm washer O-ring (key 61).
Place the sealing diaphragm plate (key 16) on the
stem followed by the O-ring (key 61), diaphragm
(key 15), diaphragm plate (key 14), spring seat
(key 13), lock washer (key 58) and hex nut (key 20)
as shown in Figure 7. To prevent diaphragm damage,
torque the hex nut (key 20) to 25 to 30 ft-lbs / 34 to
41 N•m, while using 3/4 in. / 19 mm wrench ats on
the stem.
2. If the street elbow (key 51) was removed, it
must be reassembled before mounting the
casing adaptor (key 60). Apply PTFE sealant
or equivalent around the external threads of
the street elbow and tighten to a torque of 20 to
35 ft-lbs / 27 to 47 N•m. Position the control line
connection (street elbow) so that it points away
from the casing adaptor.
3. Lubricate the O-rings (keys 19, 32 and 54) and
install as shown in Figure 8. Install the casing
adaptor (key 60) to the lower casing (key 7) and
tighten the cap screws (key 53) to 20 to 30 ft-lbs /
27 to 41 N•m of torque.
4. Insert the stem bearing (key 6) and carefully insert
the stem (key 18) into the lower casing (key 7) and
casing adaptor (key 60) assembly.
5. Assemble the upper diaphragm casing (key 52),
mounting plate adaptor (key 56) and mounting
plate gasket (key 57) as shown in Figure 9.
Tighten the cap screws (key 55) to 20 to 30 ft-lbs /
27 to 41 N•m of torque.
6. Assemble the upper and lower casings, noting that
two of the holes in the 5-1/4 in. / 133 mm diameter
