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 ispushed 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 Sections12 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 surethat 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 100psig (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 thegage.

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,
ifapplicable.
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 inthe 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 itthrough the stem sleeve and yoke.
5. Remove the stem packing retainer, stem packing, stem packing gland and, if Model550 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.
8 REMOVAL - DISASSEMBLY - REASSEMBLY
