5. Gasket installation
5.1 2 In Body – Slip the gasket (key 12)
over the guide post (key 13) and
hold the wave spring, if used, between
the ball and the body. Insert
the guidepost assembly into the
body, wave spring, and ball valve.
5.3 3, thru 8 inch bodies - Slide both the
gasket (key 12) and the spring retainer
washer (if required) over the guide post
(key 13) and hold the wave spring, if
used, between the V-ball and the body.
Insert the guidepost assembly into the
body, wave spring, and ball valve.
6. Insert the retainer for the guidepost and secure
with retainer nuts; for body sizes 2-through
8 inch. Tighten nuts to the recommended
torque from table 1.
7. Insert groove pin (key 10) to lock the drive shaft
and V-ball connection. The pin should enter
from the large hole and go towards the
smaller diameter hole. The pin
should be flush with both ends.
8. Replace the packing box ring (key 18) and
install the new packing (key 6).
9. Install the packing follower (key 15) and replace
the packing flange if used. Replace and tighten
the packing flange nuts until they are finger
tight. When under actual flow conditions the
nuts will need additional tightening to
control leaking.
10. Following the instructions under ‘Ball Seal or
Flow Ring Maintenance”, replace the ball seal or
flow ring.
11. Reconnect the actuator using the actuator orien-
tation that was noted previously. The cap
screws (key 4) and hex nuts (key 5) should be
torqued to the values listed in Table 1.
12. Install the lever using orientation that was noted
previously and the identifying marks from figure
3.
13. Use the appropriate actuator instructions for
remaining mounting instructions and the travel
adjustment.
Bushing Replacement
Jordan Valve does not recommend replacing bushings
in the field. The procedure is difficult and may cause
permanent damage to the V-ball. If replacement of the
bushing in the field is necessary, follow the instructions
that follow and the dimensions in Figure 5.
Note:
Do not heat the valve in an attempt to ease the
replacement procedure of the body bushing. Heat-
ing the valve will cause the plastic-lined material to
release fluorine gas, which is extremely hazardous,
causing; poisoning, suffocation, and burns.
