Instruction

Manual

GENERAL

This manual provides installation, operation and mainte­nance instructions for the Model 9000 control valve. To
insure operator safety and optimum performance, these
instructions should be read, understood and followed. The
Model 9000 technical brochure or appropriate engineering
drawings, should be used in conduction with this manual.

UNPACKING

To minimize damage during transit, most Badger® products
are shipped in heavy double wall boxes and packed in high
density Insta-Pak foam.
> If the container is damaged, the carrier should be
notified immediately and appropriate claims filed by your
company.
> Inspect each item for possible damage and verify item
quantity with the packing list.
> Leave all products in their protective packaging until
ready for installation.
> Leave flange surface protectors in place until ready for
installation.

INSTALLATION

> Clear pipeline of debris before installing the valve.
> Remove protective plugs or coverings from the body and
instrument air connections. Note: Leave the black “vent
plug” in place [in spring case opposite the air connection].

!

CAUTION

Do Not use the “cork” flange face protector as a gasket.
Use only gaskets approved by your company.
> The standard “flangeless/NPT” body can be piped with
NPT fittings or clamped between companion flanges.
Note: The 2" size valve cannot be clamped between Class
300 flanges due to the flange having eight [8] bolts.
> When installing with NPT fittings, use a thread sealant to
preclude galling and decrease leakage.
> Be sure to install the valve [with] the flow direction arrow
on the body unless instructed by the factory to do other­wise.
> If clamping between flanges, make sure the I.D. of the
gasket does not restrict the inlet or outlet openings of the
valve.
> Flange bolts or studs, should be applied in accordance
with ASME or your company standards.

> If vibration or shock is anticipated, a support bracket
should be attached to the actuator rim screws and attached
to a strong support structure. [Brackets are available from
the factory]

AIR CONNECTION

> The air signal to the diaphragm should not exceed the
pressure range stamped on the nameplate.
If used in conjunction with a positioner, the positioner supply
pressure should be set at no more than 60 psig, although the
diaphragm is capable of withstanding 90 psig.
> All instrument and supply air should be: clean, dry and
free of oil and debris. Any deviation can cause malfunction
or shorten the life of the valve.
> The standard air connection is 1/4" NPT.
Note: If the unit has been special ordered with a BSP Gl/4
fitting, it will be marked accordingly.
> Although conditions can vary, normally 1/4" O.D. tubing is
appropriate for air signal lines of 30' or less. If the distance
is longer, or if response is slow, larger air lines may be
required.

UNITS WITH POSITIONERS

> Connect instrument signal and supply air line to the
positoner input and supply port using a small amount of
paste type thread sealant. Do Not use TFE tape.
NOTE: Normally 25-35 psi supply air pressure is appropri­ate. If the valve does not achieve the required travel, the
supply pressure can be raised until the travel is achieved.

TESTING

> The test tag [attached to the yoke] indicates the types of
tests that were performed on the valve by the factory.
> Should the packing require adjustment, do so by turning
the gland in a clockwise direction, until the leakage stops.
DO NOT overtighten the packing as it can unnecessarily
increase stem drag and reduce performance.
> DO NOT re-orient the actuator without raising the
innervalve off the seat. Rotation of the innervalve while
under spring or air tension, will damage the seating surface.

NOTE: Although the valve will operate in any orientation,
vertical is normally recommended.
NOTE: If the valve is used in a particularly hot or cold
service, do not insulate the bonnet area. The length of
bonnet material provides protection from hot and cold, for
the stem packing.

ADJUSTMENTS

[Stem Packing]
> Standard stem packing is PTFE chevron rings, which are
designed to energize under pressure.
If adjustments are necessary, tighten the gland 1/8th turn
and check for leaks. Repeat if necessary.
> If equipped with graphite packing, the gland should be
tightened only enough to stop the leak. Overtightening can
cause excess stem drag. Note: Graphite packing normally
requires a “break-in” period.

[Body-Bonnet Gasket]
> The bonnet flange bolts should not need re-tightening.
However, if leakage does occur, tighten [in a criss-cross
pattern] to the following values:
1” Valve: (5/16” bolt thread] = 17-20 ft-lbs

1.5" Valve: (3/8" bolt thread] = 30-35 ft-lbs
2" Valve: [7/16" bolt thread] = 50-55 ft-lbs.

[Bench Setting] [ATO-Without Positioner]
> Best done on a workbench with an air station and
guages. If attempting to adjust spring loading while the
valve is in line, it is recommended to shut off the upstream
pressure to the valve while making adjustments.
> The point at which the instrument signal lifts the
innervalve off the seat is pre-adjusted at the factory. If the
incoming pressure is higher than the unit is adjusted to
handle, additional spring loading can be attained by
adjusting the stem length with the stem connector.
> To increase spring tension [bench setting], stroke the
valve off the seat, using a manually operated air signal, to
the desired bench setting. (Positioners must be by-passed.)

NOTE: The 3-15psi [3 spring] version, can be adjusted to
8-20 psi. The 6-30psi [6 spring] version, can be adjusted to
16-40psi.
> Loosen the jam nut on the stem connector [against the
bottom of the actuator stem].
> Turn the stem connector [unscrewing it out of the
actuator stem] until the innervalve touches the seat.
DO NOT attempt to increase spring tension only by turning
the innervalve. Turning the innervalve while seated will
damage the innervalve, causing galling and/or seat
leakage.
> Re-Tighten the jam nut and reduce the air signal
pressure to see if the valve now shuts off. If the anticipated
[psi air] increase is not enough, repeat the above until the
proper setting is achieved.
> Once the proper setting is achieved, the valve can be
put back into service.

ZERO ADJUSTMENT [Positioner]
Details of the positioner are not included in this manual.
However, zero adjustment is a simple matter.
Most positioners have the zero adjustment clearly marked
or indicated in the manual accompanying the positioner. >
Simply set the instrument signal to the positioner at
aproximately 3.1 psi [if 3-15psi signal].
> Adjust the zero adjusting mechanism until the valve
touches the seat [going closed].
> Check the zero point by raising and lowering the air
signal to verify the setting.

DISASSEMBLY [Valve body assembly from actuator]
Although adjustments or some repairs can be performed
with the valve in line, they are best done in a properly
equipped workshop.

!

CAUTION

DO NOT attempt any repairs or disassembly, other than
packing adjustment, while the valve is under pressure.

> If the unit is Air to open, using a manual air station, raise
the innervalve to a position between 3/4 and full open.
> While holding the stem connector with a wrench, loosen
the innervalve stem jam nut and unscrew the innervalve
completely, from the stem connector.
> Using a wrench or a hammer and punch, loosen and
unscrew the yoke lock nut.
> Lift the actuator off the bonnet.
> If the actuator is not to be disassembled, you may want
to leave the air line connected and air on the diaphragm so
that it will not be forgotten during re-assembly.

DISASSEMBLY [Body/Bonnet assembly]
> Remove the innervalve jam nut
> Remove the bonnet flange screws [or studs]
NOTE: Keep these 4 screws apart from other hex screws,
as they are high strength screws and other types of screws
should not be substituted.
> Remove the bonnet from the body by slowly twisting and
pulling, by hand, until it pulls free. DO NOT pry the bonnet
out.
> Extract the seat (if so equipped] from inside the body.
> Loosen the packing gland 2-3 turns.
> Pull the innervalve out the bottom of the bonnet.
> Remove the packing gland.
> Insert a wood, plastic or soft metal [copper or brass] rod
[aprx. 0.4-0.5"ø into the bottom of the bonnet and push the
packing cavity components out the top of the bonnet.
> Carefully remove the graphite body-bonnet gasket from
both the body and bonnet. Clean both surfaces of graphite.
> Clean out the body with an appropriate solvent or soap
and water. Use a brush as necessary.

REASSEMBLY [Body/Bonnet assembly]
[Described as if installing a new innervalve, packing kit and
gasket]
> Carefully thread the new seat into the body [if so
equipped]
> Tighten the seat (with appropriate socket] to the torque
levels below:
1" Valve = 35-40 ft-lbs

1.5" Valve = 40-50 ft-lbs
2" Valve = 45-55 ft-lbs
> Lubricate innervalve stem and guide with Silicone
grease, Krytox® or other suitable lubricant. Do Not use
lubricants that contain metal particles.
> [Holding the bonnet upright] in the packing cavity end of
the bonnet, place [over the stem].

1. the SST metal ring [packing floor adapter), making sure
it reaches the bottom of the cavity.

2. the lower TFE packing adapter [flat side down]

3. 3 rings of chevron packing.

4. the upper TFE packing follower [flat side up].

5. the packing gland [tighten only hand tight for now].
