d. If the inside surfaces are clear of hydraulic fluid,
clean the bonnet assembly and be sure to remove all
hydraulic fluid from the inside and outside of the
actuator mounting curb. This is the "cup-like" area
around the valve stem. Avoid using a cleaning solu-
tion as it may damage the rubber seals used in the
valve.
7. If the valve bonnet assembly is in good condition and is
not replaced, replace the bonnet seal. Do not reuse the
old bonnet seal. See Table 4 below for the seal number.
8. Coat seals with grease provided and position in valve
body/bonnet assembly.
9. Carefully seat the bonnet assembly on the valve body.
Be sure the seals are in their proper position. On those
valves with a spring below the disc, be sure the spring is
centered in the indentation on the inside of the valve
body.
10. After positioning the bonnet assembly, replace the
screws removed earlier.
NOTE: When replacing the bonnet assembly on the 4-
inch valve, draw it evenly into the valve body.
Finger-tighten the eight bolts. Draw the bonnet
assembly into the valve by tightening, in order,
bolts 1, 5, 7 and 3 (two turns each). Repeat until
the bonnet assembly is seated. Tighten the
remaining bolts. Torque the bolts as
follows:
Valve Size
3/4 in. (19 mm) to 1-1/2 in. (38 mm)
2 in. (51 mm) to 4 in. (102 mm)
11. Remount the actuator on the bonnet assembly. Tighten
the two set screws (50-60 inch pounds.
12. Replace the damper crank arm assembly.
13. Re-attach the wires removed from the actuator terminals
and turn on the electrical power.
14. With the gas still off, cycle the actuator to check for
proper mechanical operation.
CAUTION
Be sure to perform a bonnet seal and seat leak
check after installation.
Be sure to read and follow all instructions that come
with the actuators, valves, seal and bonnet kits.
