Available
with threaded end connections, the 202F/204F is an outstanding choice for your
general purpose and automated fluid processing needs.
Always
install your valve according to accepted industry standards and practices and
operate only within stated pressure, temperature and fluid media limits. Do not open or disassemble valve unless you
intend to replace resilient seat and gasket materials. Repair kits are available from your local
Inline representative or call 1-800-568-8998.
Your
202F/204F valve is available lever operated with our standard lockout device
Product specification sheets and technical drawings are available for
dimensional information required for proper installation and automation.
Resilient
seated valve products may wear over time resulting in loosening at component
boundaries. If leakage is detected,
tighten according to the steps and torque values outlined below. If tightening does not correct the problem,
it is time to replace your seats and seals.
A.
If valve is in line, make
sure system is purged and line, ball and cavity pressure are released before
unbolting from piping system.
B.
Remove all add-on components
such as actuators, stem extensions, etc. and set aside.
C.
Disassemble valve by
loosening end cap counterclockwise.
Remove old seats and seals and discard them. Clean and dry metal components in preparation
for reassembly.
Arrange
cleaned valve parts on workbench.
A. Stem
Assembly
1.
Place Thrust Washer on Stem sliding over threaded end and seating on
shoulder at base.
2.
Insert Stem into Body cavity
through side, threaded end first, and glide through the hole in the top of the
Body until seated.
3.
While holding Stem in place,
slide Stem Packing set over threaded end.
Stem Packing should be stacked with mating concave/convex sides facing
each other. Slide Stem Packing set over Stem, concave piece first, until
seated.
4.
Place Stem Packing Bushing
over threaded end of the Stem and lower over Stem Packing set.
5.
Position Spring Washers with
concave sides facing each other and lower set over Stem bringing them to rest
upon Stem Packing Bushing.
6.
Thread Stem Nut down Stem
and hand tighten until Stem and Packing Assembly are properly seated aligned
and fixed in position. Tighten Stem Nut
to the minimum torque specified in Table 1 and rotate slightly more until Stem
Nut flats are perpendicular to Stem flats. This will allow you to slide the Lock Washer
down Stem and into position over Stem Nut.
(Please note: torque should not exceed maximum indicated in Table 1.) Thread second Stem Nut down over Stem until
resting on Lock Washer to keep Stem Assembly locked in place for further valve
assembly and adjustments.
B.
Ball/End Cap
1.
Position the valve body with
the female threaded end resting on the workbench. The open body cavity should be facing toward
the ceiling. Place one (1) new seat into
the pocket machined into the bottom of the body cavity with the curved side
facing up.
2.
Make sure seat is properly
positioned in body cavity. Turn handle
to the normally closed position to orient the axis of the key at the base of
the stem vertically so as to facilitate ball entry. Carefully lower ball into the body cavity
gliding ball key way over stem key until cradled on seat. Rotate ball 90Ί to prevent ball from moving.
3.
Select the body seal
provided. Gently insert the body seal
into the step machined into the open end of the body.
4.
Lay valve body down on its
side on the workbench.
5.
Position the end cap with
female threaded end resting on the workbench.
Place one (1) new seat in end cap.
6.
Carefully insert the end
cap, male threaded end first, into the body cavity and rotate clockwise until
you feel resistance. Make sure that both seats are securely positioned into
their respective machined pockets before continuing. Continue hand tightening until end cap has
secured ball into position.
7.
Ball should now be loosely
secure. Turn the valve upright and
inspect to see that the stem is straight and ball orifice is aligned with the
end cap bore hole.
8.
Tighten end cap with a
torque wrench to the force values specified in Table 2.
C. Final Assembly and Test
1.
Your 202F/204F ball valve is
now ready for final assembly, adjustment, and testing. Remove top stem nut. Next, slide handle over stem. Hand-tighten stem nut until handle is fixed
in place. Secure with wrench.
2.
Submit valve to qualified valve
test facility for pressure test.
Your
repaired 202F/204F ball valve is now ready for installation and service.
