Model 9000
Series 9000 Control Valves
(for valves with model
9050 reversible actuator)
GENERAL
This manual provides installation, operation and mainte-
nance 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].
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 other-
wise.
> 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.
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.
!
CAUTION
> 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 appropri-
ate. 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.
