2. Attach a hoist or some means to support the valve.
3. Remove the line bolting. Do not attempt to pry line
flanges apart by pushing or pulling on valve actuator.
4. Slide the valve carefully from the line. To avoid
damage to gasket surfaces, do not twist the valve.
5. After the valve is completely removed from the line,
slowly relieve air pressure from the actuator.
Removing Actuator From Body
In most cases, both the body assembly and the actuator
are easier to disassemble with the actuator removed
from the body. To do so, proceed as follows:
1. Support actuator assembly by the lifting ring before
disconnecting it from the body assembly.
2. Remove the transfer case cover bolts. Carefully
pry or slide the cover plate from the end of the shaft.
3. On Valtek actuators with a clamping lever arm
design, loosen the linkage bolt.
4. Loosen the actuator adjusting screw to release
spring pressure.
5. Remove the bolts connecting yoke to the actuator
subassembly.
6. Slide entire actuator assembly off the shaft. For
Valtek actuators with a clamping lever-arm design,
it may be necessary to wedge the halves of splined
lever arm apart to loosen it from the shaft splines.
Disassembling the Body
To disassemble the body, refer to Figures 1, 2 and 5
and proceed as follows:
1. On Valdisk valves supplied with seat retainer
screws, remove the seat retainer screws and re-
tainer clips. Lift the seat retainer out of the valve
body. (Refer to Figures 1A, B, C).
2. On valves supplied with retainer snap-ring configu-
ration, carefully insert a screwdriver in the key slot
provided in the retainer; pry the retainer and snap
ring out of the valve body. (Refer to Figure 1D).
3. Remove the gland flange by removing both packing
nuts. It is not necessary to remove the studs.
4. Drive the taper pins out of the disc by tapping on the
small end of the pins using a punch and hammer.
5. Remove the end plug (optional bolted flange and
seal if applicable).
6. Remove shaft by inserting a press or a nylon rod (or
similar material) into body’s blind end, and using a
hammer, carefully tap the shaft through the body.
CAUTION: Take special care not to damage the
splined end of the shaft during disassembly.
To prevent scratching the sealing surface of the
disc while removing the shaft, place supports under-
neath the disc. This also prevents the shaft from
binding in the body as the shaft comes off the
bearing surfaces.
