514
SERIES MULTI-PORT BALL VALVES
HIGH
CYCLE TYPE
¼” – 2”
Thank
you for purchasing an Inline Industries 514 Series Multi-Port Ball Valve. This product has been constructed for
maximum performance and system design flexibility. The 514 can be used for manual operation with a standard lockout
device or easily adapted for electric or pneumatic automation. Our unique dual pattern ISO 5211 Direct
Mount actuation system enhances actuator performance, improves safety and eliminates
the need for costly brackets. Available
in 3- and 4-way “L” or “T” flow patterns, with Schedule 40 threaded end
connections and full or standard port construction, the 514 product line offers
a number of solutions for your fluid processing needs.
Installation
and Operation
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
514 is available lever operated with our standard lockout device and
incorporates an integrally cast dual pattern ISO 5211 mounting pad for electric
or pneumatic actuation. 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
is released before removing from piping system.
B.
Remove
all add-on components such as actuators and set aside.
C.
Disassemble
valve. Remove old seats and seals and
discard them. Clean and dry metal
components in preparation for reassembly.
Arrange
cleaned valve parts on workbench.
Position body with the single large bore hole facing up.
A.
Stem
Assembly
1.
Place
thrust washer on stem sliding over threaded end and seating on shoulder at
base.
2.
Place
Viton o-ring on stem sliding over threaded end and seating into groove notched
at mid-point of stem.
3.
Insert
stem into body cavity through side, threaded end first, and glide through the
hole in the top of the body until seated.
4.
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 over stem, concave piece first,
until seated.
5.
Place
stem packing follower bushing over threaded end of the stem and lower over stem
packing.
6.
Position
two spring (Belleville) washers with concave sides facing each other and lower
set over stem bringing them to rest upon stem packing bushing.
1.
Thread
stem nut down stem and hand tighten until stem and packing assembly are
properly seated, aligned and in a fixed 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.
7.
B.
End
Caps/Ball (3-Way Configuration)
1.
Your
3-Way valve has three end caps, two small end caps and one large end cap (with
a larger sized gasket). Place new
seats, curved side up, in all three end caps.
Lower the remaining seat into the body cavity, again with curved side
up, until it fits securely into the seat retainer in back of body.
2.
Make
sure seat is properly positioned.
Orient the axis of the key at base of stem vertically so as to
facilitate ball entry. Position the
orifices on the ball to match the pattern stamped into the top of the
stem. Carefully lower the ball into the
body cavity top end first, gliding the ball key way over the stem key until
cradled on the exposed seat. Please
note that the 514 has a specially mounted retaining pin fixed perpendicular to
the key way. The mating slot on the
top of the ball must engage this pin when sliding over stem key for proper
valve function.
3.
Select
the large end cap.
4.
Gently
slide the large gasket over the threaded end of the large end cap until coming
to rest on the shoulder.
5.
Invert
and gently insert the large end cap into large bore hole (facing upward) and
thread into place until it rests against gasket. Ball should now be loosely secure.
6.
Turn
valve body upright and inspect to see that the stem is straight and ball
orifice is aligned with end cap bore hole.
Use of a cylindrical dowel to properly align the axis of the ball with
the end cap is highly recommended.
Continue hand tightening until proper alignment is secured. Once positioned, tighten large end cap to
the torque specified in Table 2.
7.
Repeat
Steps 3-5 above for the two small end caps.
8.
Once
small end caps are on and proper alignment is achieved, alternately tighten
each small end cap one quarter turn with a torque wrench until reaching the
torque specified in Table 2. This
should ensure proper seating and alignment.
C. Final Assembly and Test
1.
Your
514 ball valve is now ready for final assembly, adjustment and testing. Remove top stem nut. Some models have a separate stop plate for
handle positioning. If available, place
stop plate over stem. Next, slide
handle over stem in the orientation desired for clearance of proximate piping
or as an indication of flow. (Eight
positions are possible.) 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 514 ball valve is now ready for installation and service.
