1 ABOUT THE MANUAL
This manual has been prepared as an aid and
guide for personnel involved in installation or
maintenance. All instructions must be read and
understood thoroughly before attempting any
installation, operation or maintenance.
SAFETY INSTRUCTIONS
Emerson does not have any control over the
manner in which its gagecock set is handled,
installed or used and Emerson cannot and does
not warrant or guarantee that a gagecock set
is suitable or compatible for the user's specific
application.
WARNING
Vessel fluids may be pressurized in the gage and
can exit vessel connections unexpectedly due
to apparatus or material failure. Safety glasses
should be worn when installing a gagecock.
Failure to follow any instruction could result in
a malfunction of the gagecock with resulting
sudden release of pressure, property damage
and/or physical injury.
2 INTRODUCTION
Penberthy armored OS&Y gagecocks are used
to connect gage glass, magnetic gages or other
apparatus to the holding or pressure vessel.
Penberthy Series 500 and 700 OS&Y gagecocks
are supplied in pairs (upper and lower) and are
available with socketweld, flanged and NPT
connections.
These gagecocks are equipped, as a standard
feature, with an outside screw and yoke and
with ball check shut-off to reduce leakage
of contained fluid in case of accidental gage
glass breakage. The outside screw and yoke
gagecock is designed for use where it is
necessary to have external stem threads due to
pressure, temperature or corrosiveness of the
contained fluid. All models have a solid shank
vessel connection.
2.1 System description
Penberthy armored gagecocks comprise seven
basic components. Each component may vary
slightly, depending on the desired physical
and mechanical properties for the gagecock.
Use the exploded parts views in Sections 12
and 13 as additional reference material. The
OS&Y gagecock operation differs from standard
armored process gagecocks in that the threads
are external to gagecock operation. The stem
reciprocates rather than rotates (screws) as it
seats inside the gagecock body.
Body: a pressure retaining structure through
which fluid passes to enter a gage glass or
other apparatus. Provides a rigid connection
to the vessel and seating surfaces for most
gagecock components. Series 500 is straight
pattern body; Series 700 is offset pattern body.
Yoke: seals and supports the stem packing
during gagecock operation. The yoke contains
the stem packing to prevent gagecock leakage.
The yoke is sealed with a gasket as it is
compressed against the gagecock body using
screws. (Series 550 and 750 Fugitive Emission
gagecocks use an O-ring between the yoke and
body to prevent fugitive emissions). Threads in
the yoke provide the torsional base that pushes
and pulls the stem when the gagecock is closed
and opened.
Ball checks: sphere installed loosely within
the body of the gagecock that seats to prevent
significant leakage when a differential pressure
surge occurs (e.g., mechanical failure). Ball
checks for ASME steam service incorporate
a vertically rising lower and leaky horizontal
upper or omit ball checks completely. 'Reverse
acting' ball checks are available for vacuum
service.
Trim: wetted parts that control the fluid path
from the vessel to the gage glass or other
apparatus mechanically. The ball and stem act
to seal and release the liquid. In the event of
mechanical failure, the ball will seat to prevent
large quantities of the contained fluid from
exiting the vessel. Fluids are allowed to exit the
vessel into the gage glass or other apparatus
when the stem is pulled away from its seated
position. The fluids are sealed when the stem
ispushed into its seated position.
The stem packing retainer provides a
compression surface between the process
fluid and the stem packing. A stem packing
gland is used to compress the packing against
the retainer and around the stem to prevent
leakage.
Stem packing: under compression the stem
packing is forced to mold around the stem and
prevent leakage of media during operation.
(Series 550 and 750 Fugitive Emission
gagecocks use specific packing materials
of construction to prevent vapor or gaseous
leakage).
Gage connection: provides connection between
the gagecock and the gage glass or other
apparatus. A union, spherical union or rigid
connection may be used. A union connection
can move in a plane parallel to the vessel
connection. The connection can be threaded,
flanged or welded. (Series 550 and 750 Fugitive
Emission gagecocks require rigid gage
connections only).
Handwheel/lever: rotated to engage threads
and provide reciprocating action of stem.

3 AVAILABLE MODELS
Armored gagecock standard features are listed in the table below. The model 522 and 722 are
provided with a gasketed union gage connection. The gasket is a spiral wound style, stainless
steel/graphite, which is inserted into the body at the union connection to provide a gasketed
seal between the body and tailpipe as opposed to the standard metal-to-metal joint. The gasket
provides a seal even with small angular misalignment and with less closure force than the
standard metal-to-metal seal.

3.2 Steam application
Penberthy series 780 gagecocks are designed
for steam/water flat glass gages. The stuffing
box attaches to the gagecock body with a
coupling nut. A special nipple extends from the
gage glass to the stuffing box where packing is
compression fit around the nipple like tubular
glass. The gage rests on the bottom gagecock
while the coupling nuts are tightened.
4 INSPECTION
On receipt of a gagecock set, check all
components carefully for damage incurred
during shipping. If damage is evident or
suspected, do not attempt any installation.
Notify the carrier immediately and request a
damage inspection. Refer to exploded view
drawings in Sections12 and 13 to inventory
parts.
4.1 User’s rating inspection
The user should confirm that:
1. The gagecock set model number and
pressure/temperature rating stamped on
the nameplate conforms to the description
on the user's purchase order.
2. The operating conditions described in
the purchase order agree with the actual
operating conditions at the installation site.
3. The actual operating conditions at the
installation site are within the application
data shown on the relevant technical data
sheet or product proposal referred to
previously.
4. The materials of construction of the
gagecock set are compatible with both
the contained fluid and the surrounding
atmosphere in the specific application.
SAFETY INSTRUCTIONS
If the size, model or performance data of the
gagecocks as received does not conform with
any of the criteria above, do not proceed with
installation. Contact an authorized Penberthy
distributor for assistance. The incorrect gagecock
can result in unacceptable performance and
potential damage to the gage.
5 INSTALLATION
Installation should only be undertaken by
qualified personnel who are familiar with this
equipment.
They should have read and understood all
of the instructions in this manual. The user
should refer to relevant technical data sheets
or product proposal to obtain dimensional
information for specific size and model
gagecock.
Recommendations on gagecock installations
are not necessarily related to the installation
of flat glass liquid level gages. The number
of different types of gage and gagecock
installations is too great to explain adequately
in an installation manual. Therefore, it is
the user's responsibility to assure that
knowledgeable installation personnel plan and
carry out the installation in a safe manner.
The following are some of the guidelines that
should be employed:
5.1 Piping strain
The gagecock should be mounted and
connected so that it can support the gage
without binding. Torsional stresses can make
it difficult or impossible to seal tailpipes.
Although union connections will allow marginal
errors in piping alignment, misalignment can
still create unusual strain on connectors. Gages
not properly supported by brackets may subject
the gagecock to stresses that can cause leaks
or mechanical failure. Typical gage load should
NOT exceed 50 lbs (22.7 kg) per gagecock.
5.2 Differential thermal expansion
High mechanical loading may be imposed on a
gagecock by expanding and contracting gages
due to hot or cold service. Such mechanical
loads on the gagecock must be minimized by
controlling process conditions in the system
or by using expansion loops or stuffing boxes
(Model 780).

5.3 Mounting
1 Prior to installation, turn the handwheel
of each gagecock clockwise until the stem
closes against the seat.
2. Mount upper and lower gagecocks to the
vessel using PTFE tape, or equivalent, on
all male tapered pipe thread connections
as shown in Figure 1. If the gagecock is
flanged or weld mount, use proper industry
standard procedures.
3. If installing with a flat glass gage, follow
all installation instructions for the specific
liquid level gage as there are many points to
consider on gage installation; among them,
piping strain, differential thermal expansion,
weight and bolt torque.
4. Install gage tailpipes to union gage
connections, where applicable, making
surethat coupling nuts are in place.
5.4 Stuffing box
1. Install tubular packing nut, tubular packing
gland and tubular packing to each end of the
gage connection.
2 Turn the upper gagecock counterclockwise
approximately ⅛ turn.
3. Insert the end connection of the gage into
the upper gagecock stuffing box connection
as far as it will go.
4. Tighten the upper gagecock to the original
position while holding the gage in position
with upward force to insure it clears the
lower stuffing box location.
Check vertical alignment of the gagecocks.
5. Slide the gage assembly down into the
lower gagecock stuffing box connection to
a positive stop. Tighten the upper and lower
gagecock tubular packing nuts.
6 OPERATION
Before initializing gagecock operation, check
that all installation procedures have been
completed. Use only qualified, experienced
personnel who are familiar with gagecock
equipment and thoroughly understand
the implications of the tables and all the
instructions. Check to determine that all
connections are pressure tight.
WARNING
Gagecock installations should be brought into
service slowly. Gagecocks should be opened
slightly and the gagecock assembly temperature
and pressure allowed to equalize slowly. If the
gagecocks are equipped with ball checks, the
gagecocks must be opened all the way after
the pressure and temperature have equalized
to permit operation of the automatic ball check
in the event of gage glass failure. Failure to
follow the recommended operating procedures
can result in severe personal injury or property
damage.
6.1 Hydrostatic test
Take all precautions necessary to handle the
possibility of leakage during the test.
Hydrostatic pressure test all installations to
100psig (690 kPa) and correct any leakage
before proceeding.
7 MAINTENANCE
WARNING
Use only qualified, experienced personnel who are
familiar with gagecock equipment and thoroughly
understand the implications of the tables and
all the instructions. DO NOT proceed with any
maintenance unless the gagecock assembly has
been relieved of all pressure or vacuum, has been
allowed to reach ambient temperature and has
been drained or purged of all fluids. Failure to do
so can cause serious personal injury and property
damage.
The user must create maintenance schedules,
safety manuals and inspection details for each
gagecock. These will be based upon the users
own operating experience with their specific
application. Realistic maintenance schedules
can only be determined with full knowledge of
the services and application situations involved.
During system shutdown, the gagecocks should
be left open to permit the gage to lose pressure
and cool with the rest of the system. Failure
to leave the gagecock open during system
shutdown may trap high-pressure fluid in
thegage.

7.1 Preventative maintenance
On all installations, the following items should
be evaluated regularly by the user for purposes
of maintenance:
1. Leakage between the body and the yoke.
2. Leakage around stem area.
3. Internal stem leak.
4. Leakage around union connection.
5. Leakage around stuffing box connection,
ifapplicable.
6. Internal or external corrosion.
The user must determine an appropriate
maintenance schedule necessary for his or
her specific application, upon evaluation of
their own operating experience. Realistic
maintenance schedules can only be determined
with full knowledge of the services and
application situation involved.
7.2 Re-certification program (FE gagecocks)
Stem packing material may wear with extensive
operation of the gagecock. Over time leak
paths may develop that cause the emission
rate to exceed 5 ppm. Including gagecock
re-certification in gagecock maintenance
schedules is recommended. For a nominal
service charge, gagecocks can be returned
to the factory for testing. In most instances,
if leaks above 5 ppm are found, Emerson can
replace the packing, retest the gagecock and
return the gagecock for service.
Contact your distributor for price information.
7.3 Ball check shut-off
SAFETY INSTRUCTIONS
Ball checks, when installed, may fail to seat due
to corrosion of the ball or seat, foreign material
in ball chamber or viscous material in the ball
chamber. A routine operational test of the ball
check can prevent significant seepage of liquid
inthe event of glass breakage.
An operational check can be performed on the
gagecock ball check by closing both the upper
and lower gagecock stems completely. Drain
contents from and relieve pressure on liquid
gage to an appropriate safe container/area.
Note: some loss of process fluid to the drain
line is expected with this test procedure.
WARNING
Use only qualified, experienced personnel who are
familiar with gagecock equipment and thoroughly
understand the implications of the tables and
all the instructions. DO NOT proceed with any
maintenance unless the gagecock assembly has
been relieved of all pressure or vacuum, has been
allowed to reach ambient temperature, and has
been drained or purged of all fluids. Failure to do
so can cause serious personal injury and property
damage.
With the drain line in place, open the BOTTOM
gagecock as rapidly as possible. Listen for
'click' sound, which will indicate that the ball
has seated. If possible, observe the quantity
of flow from the drain line. Flow should either
stop completely or be no greater than single
drips (no solid stream). Close lower gagecock.
Repeat above procedure for UPPER gagecock.
There must be a pressure differential of at least
5 psig (35 kPa) for the above procedure to work
properly.
If the above procedure is not successful, the
only alternative is to isolate the gage and
gagecock assembly from the vessel or to shut
the process down completely. Disassemble the
gagecock as outlined in Section 8.1 using the
exploded parts drawings in Sections 12 and 13
as a reference. Visibly inspect ball check and
ball seats in the gagecock body. Remove any
foreign matter and/or replace with new ball
checks if inspection indicates this is required.
If the ball seat is damaged, consider replacing
the gagecock or the seat. Reassemble
gagecocks as outlined in Section 8.2.
7.4 Troubleshooting
Leakage between the body and yoke can often
be stopped by tightening the yoke and screws.
If leakage persists, the yoke gasket should be
replaced by following steps 1) and 2) of the
Disassembly and 4) and 5) of the Reassembly
instructions. The Models 550 and 750 Fugitive
Emission gagecock use an O-ring to seal the
yoke to the body. Follow steps 1) and 2) of the
Disassembly and 4) and 5) of the Reassembly
instruction to replace O-ring.
Stem packing leakage can often be stopped by
tightening the stem packing follower screws.
If leakage persists, the stem packing should
be replaced by following steps 1) through 5)
of the Disassembly and 1) through 6) of the
Reassembly instructions. If the gagecock set is
equipped with Grafoil
may be stopped by adding an additional ring
of packing in the packing stuffing box. Turn
the handwheel counterclockwise until it seats
against the stem packing retainer. Remove
the stem packing follower screws. Slide the
stem packing follower and gland away from the
packing stuffing box. Insert an additional ring
of packing in the stuffing box. Slide the stem
packing gland and follower down against the
packing and tighten the stem packing follower
screws.

Internal seat leakage is an indication of a worn
or damaged stem or seat. To replace the stem
follow steps 1) through 5) of the Disassembly
and 1) through 6) of the Reassembly
instructions. To replace the seat, follow steps 1)
and 2) of the Disassembly instructions.
Remove the seat by inserting a ¼" square driver
in the seat and turning it counterclockwise.
Replace the new seat by turning it clockwise
using a ¼" square driver, making sure that
the ball check, if used, is replaced in the body.
Tighten the seat in place. Follow steps 4) and 5)
of the Reassembly instructions.
Leakage around union connections can often
be stopped by tightening union coupling nut or
remaking the connection using PTFE tape, or
equivalent, on all male pipe threads as shown
in Figure 1. For small angular misalignment an
accessory sealing gasket is available - contact
your purchasing source.
Leakage around the stuffing box connection
indicates worn out tubular packing or improper
compression of the packing. To replace the
packing, follow step 7) of the Disassembly and
step 8) of the Reassembly instructions. In the
event of improper compression, leakage can be
stopped by tightening the tubular packing nut.
2. Remove the yoke gasket and, if Model 550 or
750 FE gagecock, yoke O-ring.
3. Remove the handwheel nut, washer,
nameplate and handwheel.
4. Remove the stem from the yoke by pulling
itthrough the stem sleeve and yoke.
5. Remove the stem packing retainer, stem
packing, stem packing gland and, if
Model550 or 750 FE gagecock, Belleville
washers from stem.
6. For gagecocks equipped with a union
connection, remove the coupling nut and
tailpipe.
7. For gagecocks equipped with a stuffing box
connection:
a. Loosen the tubular packing nut on both
the upper and lower gagecocks.
b. Slide the gage assembly into the upper
gagecock as far as it permits.
c. While holding the gage in this upward
position, rotate the upper gagecock
counterclockwise approximately ⅛ turn
to allow clearance to remove the gage
from the lower gagecock.
d. Remove the gage from the upper
gagecock.
e. Remove the tubular packing nut, tubular
packing gland and tubular packing from
both the upper and lower gagecock.
Internal or external corrosion could be an
indication of a misapplication. An investigation
should be carried out immediately to
determine the cause of the problem. It
is the user's responsibility to choose a
material of construction compatible with
both the contained fluid and the surrounding
atmosphere.

individually serialized and tested to meet EPA
emission test requirements. Each gagecock
is shipped with its individual test report that
certifies less than 5 ppm leak rates, using
®
Kalrez
and PTFE as the packing material.
Refer to product proposal information for
packing materials other than Kalrez
®
and PTFE.
10 DISPOSAL AT END OF USEFUL LIFE
Penberthy gagecocks are used in a variety of
fluid applications. By following the appropriate
federal and industry regulations, the user
must determine the extent of preparation and
treatment the gagecock must incur before its
disposal. A Material Safety Data Sheet (MSDS)
may be required before disposal services
accept certain components.
There is a minimum charge for evaluation
of non-warranty units. You will be contacted
before any repairs are initiated should the cost
exceed the minimum charge. If you return a
unit under warranty, but it is not defective, the
minimum charge will apply.
