I. GENERAL INFORMATION
A. Description and Features
The FLS-TC gate valve is a forged, full-bore, through-conduit valve available in standard double flange and special block body configurations. The
following are features of the FLS-TC gate valve:
1. Bi-directional design provides flow direction versatility and increased
service life.
2. Positive metal-to-metal sealing (gate-to-seat and seat-to-body).
3. Simple, reliable gate and seat design promotes ease of field service
and minimal spare parts inventory.
4. Two spring-loaded, pressure energized, non-elastomeric lip-seals between each seat and body assist in low pressure sealing. They also protect against intrusion of particle contaminants into the body cavity
and seal areas.
5. Stem seal design covers full range of pressures, temperatures, and fluids encountered in wellhead and manifold service.
6. Metal-to-metal bonnet seal, (pressure energized 10,000 psi WP and
above).
7. Stem can be backseated to allow stem seal replacement with the valve
under pressure.
8. Grease injection fitting located downstream of stem backseat for
safety. Fitting located in bonnet, eliminating body penetration.
9. Bearing cap grease fitting allows positive bearing lubrication.
10. An optional add-on torque multiplier is available to provide easier operation.
11. Bearing Cap incorporates a eutectic ring which, upon melting in a fire,
allows the stem to automatically move to the backseat sealing position against the bonnet.
a. Stem cross-sectional area is sized to provide adequate force from
valve pressure to backseat the stem, overcoming gate drag friction.
b. Springs within the bearing cap move the stem to the backseat position in the event there is minimal pressure in the valve.

12. See the valve assembly bill of material for component part numbers
and description.
B. Operating Instructions
A gate valve should always be in either the full-open or full closed position. Leaving the gate partially open or throttling through the valve could
cause damage to the gate.
The valve is opened by turning the handwheel counterclockwise (to the
left) until it stops (when the top of the gate contacts the bonnet). Then
turn the handwheel back to the right ¼ turn to relieve any stress in the
stem. Initial torque required to open the valve is shown in Table I.
The valve is closed by turning the handwheel clockwise (to the right) until
it stops and then backing off (counterclockwise) ½ to ¾ turn. The number
of turns required to move the valve from full open to full closed is shown
in Table II.

2. Recommended thrust bearing lubricant
a. For normal operation, use Cameron standard valve lubricant, which
is not affected by water or temperatures ranging from -20º to
+250ºF.
b. For continuous service below 0ºF, use one of the two available low
temperature greases.
3. Recommended anti-seize compound where specified, use High
Nickel/High Temperature anti-seize compound, P/N 711227.
B. Body Cavity Lubrication
1. Normal Operating Conditions
Cameron lubricates gate valves on assembly. Lubricate the body cavity
after ten operating cycles.* If the valve is removed from service, lubricate the body cavity before returning it to the line.
a. Remove the grease fitting cap. Refer to Figures 5 and 6.
b. Using either a bucket type gun, P/N 19873-03, or hand-held type,
P/N 19873-01, connect the grease gun coupler to the grease fitting.
c. Pump the appropriate amount of lubricant into the body cavity.
Refer to Table IV.
* One cycle opening and closing the valve one time. The service interval can vary
according to application, fluids used, and well conditions. If pressure is equalized
across the valve before the valve is opened, the service interval can be extended.
2. Unusual Temporary Operating Conditions
If it becomes necessary to cement through, acidize through, or subject
the valve to any other unusual service:
a. Lubricate the valve body cavity before it is put into operation.
b. Flush the valve with appropriate neutralizing fluid after it is removed from service.
c. Operate the valve with fresh water or appropriate neutralizing
fluid in the line.
d. Lubricate the valve body cavity.

IV. ORDERING REPLACEMENT PARTS
The only information needed for ordering replacement parts for a Cameron
gate valve is the original valve assembly part number and the description of
the part. The valve assembly part number is stamped on the valve body nameplate. It is recommended that a description of the valve assembly (size, pressure, trim) be included as a check on the assembly number, but this is not
necessary if the assembly number is clearly readable.
It is not recommended to order replacement parts by using the part number
off the old part or by referring to a file copy of the valve assembly bill-ofmaterial. If an engineering change has been implemented to the valve assembly to replace one component part number with another, the only way to ensure getting the updated component is to reference the valve assembly
number and to reference the part by description (gate, seat, stem, etc). Part
descriptions are shown in the parts lists, Part ID Cameron personnel can then
check the latest revision of the assembly bill-of-material to obtain the appropriate and current replacement part number.

V. STEM SHEAR PIN REPLACEMENT
A. Procedure for design with shear pin retained by set screws as shown in
Figure 2. Item numbers in parentheses refer to Figure 2.
The two shear pins (item 2) can be replaced with pressure in the valve,
with the gate in any position (open to closed), and without engaging the
stem backseat. The pin through the stem adapter (1) and stem (21) is subjected to operating torque only. The pin through the bearing mount (9)
and stem (21) locks the bearing mount position on the stem.
1. Remove the handwheel (34).
2. Remove the two set screws (8) from the stem adapter (1).
3. Remove the stem adapter-to-stem pin using a small hammer and
punch. If the pin has sheared, it probably will not come out - do not
try to force it. Pull the stem adapter (1) off the stem and remove
sheared pieces of the pin from both parts.
4. Remove the bearing mount-to-stem pin using a small hammer and
punch. Maintain the rotational position of the bearing mount (9) with
respect to the stem.
Caution: The two shear pins are made from a specific material, heat treated to a
closely controlled strength. Therefore, do not substitute different pins.
This could result in premature shearing of a pin during valve operation, or
damage to valve components. Use only replacement pins per the part
number on the Cameron bill of material for the specific valve being serviced.
5. Reinstall both pins if in good condition, or replace with new pins as
needed per the Cameron part number for the specific valve.
6. Replace the two stem adapter set screws (8).
7. Replace the handwheel (34).
B. Procedure for design with shear pins retained by a collar as shown in Figure 3. Item numbers in parentheses refer to Figure 3.
The two shear pins (item 2) can be replaced with pressure in the valve,
with the gate in any position (open to closed), and without engaging the
stem backseat. The pin through the stem adapter (1) and stem (26) is subjected to operating torque only. The pin through the bearing mount (6)
and stem (26) locks the bearing mount position on the stem.
1. Remove the handwheel (40).
TC1354
24
2. Remove the retainer ring (8).
3. Remove the collar (3), held only by friction of O-ring, lip seal, etc.
4 Remove the stem adapter-to-stem pin using a small hammer and
punch. If the pin has sheared, it probably will not come out - do not
try to force it. Pull the stem adapter (1) off the stem and remove
sheared pieces of the pin from both parts.
5. Remove the bearing mount-to-stem pin using a small hammer and
punch. Maintain the rotational position of the bearing mount (6) with
respect to the stem.
Caution: The two shear pins are made from a specific material, heat treated to a
closely controlled strength. Therefore, do not substitute different pins.
This could result in premature shearing of a pin during valve operation, or
damage to valve components. Use only replacement pins per the part
number on the Cameron bill of material for the specific valve being serviced.
6. Reinstall both pins if in good condition, or replace with new pins as
needed per the Cameron part number for the specific valve.
7. Clean and grease surfaces of the collar (3) that contact the bearing
cap lip seal (10) and the stem adapter O-ring (9). Replace the collar.
8. Replace the retainer ring (8).
9. Replace the handwheel (40).

6. Prevent stem rotation with a high strength rod through the stem
adapter shear pin hole in the stem. Then use the wrenching flats to
turn the bearing mount (9) clockwise (to the right) to move the stem
and gate (28) until the stem backseat shoulder firmly contacts the
bonnet.
B. Procedure for Designs with Shear Pins Retained by Collar as Shown in Figure 3. Item numbers in parentheses refer to Figure 3.
1. Remove the handwheel (40).
2. Remove the collar retainer ring (8).
3. Remove the collar (3).
4. Remove the bearing mount (9)-to-stem shear pin (2), but do not remove the stem adapter (1)-to-stem shear pin (2).
5. Prevent stem rotation with a wrench on the stem adapter (1). Then
use the wrenching flats to turn the bearing mount (9) clockwise (to
the right) to move the stem and gate (28) until the stem backseat
shoulder firmly contacts the bonnet.
C. Alternates: Using ‘Conventional’ Backseating Procedures.
The following ‘standard’, more familiar backseating procedures used for
most Cameron gate valve models may also be used. The previously described procedures, A or B, require considerably less effort (torque) to
backseat an FLS-TC valve.
1. Procedure for Conventional Threaded Bearing Cap Designs as Shown
in Figure 2. Item numbers in parentheses refer to Figure 2.
a. Close the valve fully.
b. Loosen the bearing cap (10) – turn counterclockwise (to the left)
four complete turns.
c. Turn the handwheel clockwise (in the closing direction) until the
gate firmly contacts the bottom of the body cavity and the stem
moves outward until the backseat shoulder contacts the bonnet.
d. ‘Bump’ the handwheel in the closing direction for firm backseat
contact.
TC1354

2. Procedure for Designs with Bearing Cap Retained by a Threaded
Retainer as Shown in Figure 3. Item numbers in parentheses refer to
Figure 3.
a. Close the valve fully.
b. Loosen the bearing cap retainer (17) – turn counterclockwise (to
the left) four complete turns.
c. Turn the handwheel clockwise (in the closing direction) until the
gate firmly contacts the bottom of the body cavity and the stem
moves outward until the backseat shoulder contacts the bonnet.
d. ‘Bump’ the handwheel in the closing direction for firm backseat
contact.
VII. BACKSEAT SEAL VERIFICATION
A. For Valves Rated 10,000 psi (69 Mpa) WP and Below
Refer to Figure 2 and Figure 5.
Note: As an option, the high pressure fitting (Refer to Section VII.B.) may be utilized
in a valve rated at 10,000
psi (69 Mpa) and below.

3. Replace the cap slowly until the check valve ball in the fitting is unseated, and the pressure trapped by the backseating process is vented.
4. If pressure escapes quickly and then stops, valve body pressure is being
held either by the backseat, or possibly by a “buried” check valve (23)
in the grease fitting flow port (located as shown in Figure 2 or perhaps deeper into the port, particularly for a clad valve).
TC1354
27
Note: Standard FLS-TC gate valves do not have a “buried” check valve in the
grease fitting flow port. However, an extra check valve may be present in a
‘special’ valve bonnet. Therefore it is important to review the bill of material
for the specific valve being serviced, and the assembly drawing referenced
on the bill, to determine if there is a buried check valve in the grease port.
a) Remove the grease fitting cap.
b) Remove the grease fitting from the bonnet.
c) Remove the .125” (3.1mm) diameter pin from the grease fitting.
5. Determine whether or not a “buried” check valve is installed in the
grease fitting flow port. If no buried check valve exists, the backseat
seal has been verified in previous step 4. If the bonnet grease port
contains a buried check valve, proceed to Paragraph C on page 29.
B. For Valves Rated 15,000 psi (103.5 Mpa) WP and Above
Refer to Figure 6.
Note: The standard high pressure grease fitting is a
special metal sealing fitting containing a check
valve. The bonnet port is
a special configuration
with a straight thread,
rather than a pipe thread,
which accepts only this fitting design. As an option,
the high pressure fitting
may be incorporated in a
valve rated at less than
15,000 psi. Do not use
PTFE tape or thread sealant on these fittings.

3. If pressure escapes quickly and then stops, valve body pressure is being
held either by the backseat, or possibly by a “buried” check valve (23)
in the grease fitting flow port (located as shown in Figure 2, or perhaps deeper into the port, particularly for a clad valve).
Note: Standard FLS-TC gate valves do not have a “buried” check valve in the
grease fitting flow port. However, an extra check valve may be present in a
‘special’ valve bonnet. Therefore it is important to review the bill of material
for the specific valve being serviced, and the assembly drawing referenced
on the bill, to determine if there is a buried check valve in the grease port.
a) Remove the grease fitting cap.
b) Remove the grease fitting from the bonnet.
4. Determine whether or not a “buried” check valve is installed in the
grease fitting flow port. If no buried check valve exists, the backseat
seal has been verified in previous step 3. If the bonnet grease port
contains a buried check valve, proceed to Paragraph C below.
C. For Valves with Special “Buried” Check Valve Below Grease Fitting
If the bonnet grease port contains a buried check valve, then valve body
pressure must be vented through the buried check valve to determine if
the backseat seal is effective. Unseat the ball in the buried check valve using a special Cameron unseating tool. Refer to the valve bill of material
for the tool part number.
1. Using the unseating tool, unseat the buried check valve to vent pressure trapped by the backseating process.
2. If pressure escapes quickly and then stops, valve body pressure is being
held by the backseat. The backseat seal and the buried check valve
seal have been verified to be effective.
a) Replace the bonnet grease fitting (with cap removed).
b) Install the grease fitting cap.
3. If no pressure escapes, valve body pressure is being held by the backseat. However, the buried check valve is apparently defective (leaking).
a) Remove the buried check valve unseating tool and replace the buried check valve.
b) Replace the bonnet grease fitting (with cap removed).
c) Install the grease fitting cap.
TC1354
29
4. If pressure continues to escape, the backseat seal is ineffective.
a) Remove the buried check valve unseating tool.
b) Replace the bonnet grease fitting (with cap removed).
c) Install the grease fitting cap.
d) Repeat the Backseat Seal Engagement procedure per Section VI.
e) Repeat Step VII: Backseat Seal Verification.

a. For Standard Flat or Ring Type Gasket Designs
Remove by hand, being careful not to scratch or otherwise damage
gasket sealing surfaces in the body or bonnet.
b. For Special SRL Straight Bore Sealing Gasket Designs
Note: Item numbers in parentheses refer to Figure 4.
It is recommended that a new SRL gasket (23) be installed any time
the bonnet has been removed. However, if necessary, the SRL gasket can normally be reused if it has not been scratched or otherwise damaged. An SRL gasket is most likely to be reused in
circumstances such as lack of a new gasket, lack of the special installation and removal tool kit.
If the SRL gasket is going to be reused, it should not be removed
from the body (or bonnet if it remained in the bonnet upon disassembly). Also, the O.D. sealing surface of the gasket that is exposed
beyond the body (or bonnet) face should be protected from damage by a thin wrap with duct tape or similar means.
Normally, the SRL gasket will remain in the valve body when the
bonnet is removed. In the event the gasket remains in the bonnet
upon disassembly, the installation and removal tool kit can be used
to remove the gasket from the bonnet. The following instructions
are for removal of the SRL gasket from the valve body.
Note: Item numbers in parentheses refer to Figure 7.
1) Attach the removal tool (1) to the SRL gasket ‘flange’ with cap
screws (5). Lubricate the threads with valve assembly grease to
prevent galling.
2) Install the all-thread rod (3) into the removal tool (1) to approximately one rod diameter depth. Lock in position with a hex nut
(4) as shown.
TC1354
42
3) Place the load plate (2) over the threaded rod (3), contacting at
least four bonnet studs, 90 degrees apart, that are installed to
full normal depth in the valve body (so that the plate will be
parallel to the body bonnet face).
4) Apply grease to all the all-thread rod threads that extend beyond the load plate. Apply grease to the hex nut threads and
bottom face. Tighten the nut clockwise against the load plate to
pull the SRL gasket out of the body.

Note: Item numbers in parentheses refer to figure 2.
Caution: For a valve oriented with the flow bore vertical, such as in Christmas tree
applications, do not remove the gate (28) until the upper seat (29) has
been secured in position by special tooling. The heavy seat is free to fall
when the gate is removed if not held in the seat pocket by special tooling.
Refer to the bill of material for the specific valve being serviced for part
numbers of seat installation/removal tooling (normally in the ‘Optional
Items’ category of the bill of material).
8. Pull the gate (28) from between the seats (29).
Caution: For T-slot type gates with separate gate neck, the gate neck is not mechanically fixed to the gate. A “T-head” on one end of the gate neck fits
into a “T” shaped slot in the top of the gate. This loose connection allows
free side to side movement of the gate neck with respect to the gate.
9. Remove the seats from the body. If necessary, pry the seats loose with
a large screwdriver engaging the seat OD groove.
10. Remove the retainer plate (27) from the bottom of the body cavity.
B. Parts Cleaning and Inspection
1. Clean the body cavity and body cavity parts. Be careful not to scratch
or otherwise damage sealing surfaces. Sealing surfaces are identified
in the following inspection instructions.
2. Inspect sealing surfaces for scratches, galling, corrosion, coating flaws,
or other damage.
3. Inspect flat faces in both seat pockets in the body (32).
4. Inspect bonnet seal ring surfaces of the body (32) and bonnet (22).
5. Inspect front and back faces of both seats (29).
6. Inspect sealing lips of the seat lip seals (30 and 31).
7. Inspect both sides of the gate (28), and internal gate neck threads.
8. Inspect stem threads that engage the gate neck threads.
9. Inspect the retainer plate (27) for distortion, build-up of solid materials, etc.
10. Replace any damaged parts.

C. Gate and Seat Installation
1. Install the Bonnet Gasket
A. For Standard Flat or Ring Type Designs
Standard bonnet gaskets should be installed just prior to bonnet
installation as described later in this procedure.
B. For Special SRL Straight Bore Sealing Gasket Designs
Note: Item numbers in parentheses refer to Figure 8.
1) If the bonnet studs had been removed from the body, install the
bonnet studs in the body.
Apply anti-seize to the threads in the body and to the ‘short
thread end’ of each stud. Thread the short thread end of each
stud into the body until it ‘bottoms out’ with full thread engagement (engagement length equivalent to stud diameter).
2) Apply a light coating of valve assembly grease to the sealing surfaces on one end of the gasket, and to the sealing bore and
lead-in chamfer in the body.
3) Place the gasket in the body counterbore, resting on the lead-in
chamfer. Place the installation tool (1) over the gasket, contacting the gasket O.D. flange. Place the load plate (2) over the bonnet studs as shown, contacting the installation tool.
For valves mounted horizontally, such as in a Christmas tree, it
may be necessary to hold the SRL gasket in place by attaching
the removal tool (1) to the SRL gasket flange with cap screws (5).
4) Apply anti-seize to the stud and bonnet nut threads. Install four
bonnet nuts 90 degrees apart, hand tight, aligning the load
plate (2) parallel with the bonnet face of the body.
5) Tighten the four bonnet nuts evenly in a criss-cross sequence
(1,3,2,4), keeping the load plate parallel to the bonnet face, to
press the gasket into the body counterbore. Continue until all
four nuts are tight, indicating that the gasket flange has bottomed out in the body counterbore.
6) Remove the four bonnet nuts, load plate (2), and installation
tool (1).

Figure 8 - SRL Gasket Installation: using 4 Studs, 90° Apart, tighten Nuts Evenly.
2. Apply a coat of grease to the retainer plate (27) and place it in the
bottom of the body cavity, oriented as shown in Figure 2.
3. Apply a very thin film of grease to the body seat pockets (22).
4. Apply a light coat of grease to the lip seals (30 and 31) and install in
the seat grooves.
5. Apply a very thin film of grease to the back face of the seat (29), (lip
seal side).
TC1354
46
Caution: A heavy coat of grease between the OD and ID lip seals (30 and 31) may
cause damage or prevent installation of the gate into the valve.
6. Install the seats with lip seals into the body seat pockets, oriented
with the lip seals contacting the body.
7. Pack the stem threads in the gate neck (28) with grease.
8. Apply a coating of grease to both faces and bottom lead-in chamfers
of the gate, and to the faces of both seats.
9. Align the gate’s bottom edge lead-in chamfers with the seats and
push the gate between the seats.
Caution: For T-slot type gates with separate gate neck, the gate neck is not mechanically fixed to the gate. This loose connection allows free side to side
movement of the gate neck with respect to the gate. Therefore, the gate
neck must be held in place until the gate is moved far enough into the
body that the seats retain the gate neck in the gate.
10. Apply a very light coating of grease to a new flat type or ring type
bonnet gasket (24) and place on the bonnet face of the body. For special SRL gasket, refer to step C.1.
11. Using appropriate lifting equipment, lift the relatively heavy bonnet
assembly and position adjacent to the bonnet face of the body. Orient
the bonnet grease fitting toward the front side of the body, 90 degrees away from the valve bore.
12. Apply a coating of grease to the stem threads.
13. Engage the stem threads into the gate neck threads, rotating the stem
counterclockwise (left hand thread). Thread the stem into the gate
neck while moving the bonnet toward the body (guiding the bonnet
stud holes over the studs) until the bonnet is in contact with the bonnet gasket, and the gate is pulled close to the bonnet.
14. Install the bonnet nuts and tighten in an even pattern. Refer to Table
VI for torque requirements.
TC1354
47
Table VI: Recommended Bonnet Nut Torque
The torque values shown in these tables are extracted from API 6A 17th Edition,
Appendix D. The values are for user convenience only. They were calculated for
two different bolt yield strengths: 105 KSI (i.e. B7) and 80KSI (i.e. B7M); and also
for different coatings used on the bolts: ¦ = 0.13 (zinc/cadium plated) and ¦ = .07
(fluoropolymer such as Xylan 1052). All values shown assume that both the threads
and nut face are well lubricated with thread dope or a suitable grease. Choose the
bolt torque based on bolt size, material yield strength, and coating.
