FOREWORD
Flowserve Corporation, Flow Control Division, has established this Installation, Operating and
maintenance Manual to facilitate field installation, operation and repair of Flowserve TX2 Triple
Offset Butterfly Valves
It is recommended that questions or concerns involving the processes described in this manual be
directed to the local Sales Representative of Flowserve Corporation. Only Flowserve
replacement repair parts should be used. Part numbers referenced in the following sections are
available from Flowserve Corporation, Flow Control Division.

SECTION I
THEORY OF OPERATION
The valve design is based on a double eccentric geometry of the disc rotating center, utilizing a floating
radius machined seal ring, in conjunction with an inclined cone seating surface of body. This design
makes the disc cam back and away from body seat, eliminating wear between the seat and seal ring. It
also compensates for deviations of the geometry caused by temperature or tolerance changes. (Fig. 1)
The disc seal of valve deflects from its regularly circular shape to an elliptic form when it reaches the
closed position. This matches the inclined cone of body seat geometry, creating the sealing between disc
seal and body seat. Dimension changes due to temperature fluctuations cause the seal ring to adjust its
seating position within the inclined cone geometry, thus maintaining a positive seal as usual.
Due to the unique conical surface of the valve, there is a “preferred” and “non-preferred” flow direction.
The preferred flow direction would be with the shaft upstream and the direction is marked on the body
with a directional arrow. The shaft side is referred to as the high pressure side of the valve.
SECTION II
PRELIMINARY PRECAUTIONS
FOR SAFETY, FOLLOW THESE CAUTIONS BEFORE INSTALLING, REMOVING OR
DISASSEMBLING YOUR VALVE.
1. MUST KNOW WHAT MEDIA IS IN THE PIPELINE.
2. MAKE SURE THE LINE IS DEPRESSURIZED.
3. USE PROTECTIVE CLOTHING AND EQUIPMENT TO AVOID INJURY. KEEP HANDS AND
OTHER BODY PARTS OUT OF THE VALVE.
4. ALWAYS ENSURE THE VALVE IS IN THE FULLY CLOSED POSITION BEFORE
INSTALLATION, REMOVAL OR DISASSEMBLY.
5. ENSURE THAT FLANGE FACES ARE CLEAN BEFORE INSTALLATION IN PIPELINE.

Page 4
Fig. 2
SECTION III
INSPECTION
1. Before installation of the valve into the piping system, visually inspect the valve to determine
if any damage has occurred during shipping. Particularly, inspect the actuator, shaft, valve
interior, valve body and flanges. For proper operation of the valves, the seat and disc seal
must be undamaged and free of foreign material. If other than superficial damage is
discovered, contact Flowserve immediately, indicating the location and extent of the damage
found.
2. If it is necessary to clean the valve, use a soft cloth and mineral spirits, or an equivalent
solvent. All rust preventive should be removed before installing your valve.
SECTION IV
TOOL REQUIREMENT
Flow Control Division
There are no special tools required for installation and maintenance that are not commercially available.
Any lifting devices used to move the valve into a desired position shall be of sufficient size to support the
weight of the valve and actuator assembly. Nylon slings secured around the valve bearing areas are
recommended to reduce the possibility of mechanical damage occurring to the valve body and actuator.
The assembly should never be lifted by the actuator. (Fig.2)
WARNING
NEVER pass a lifting device through the valve port or severe damage may
occur.

SECTION V
STORAGE
When the valve is not put into immediate service, it is required that the valve be stored in a heated building that is
fire resistant, weather tight and well ventilated. Storage area shall be situated and constructed so that it will not be
subject to flooding or the presence of any corrosive chemicals. Flowserve recommends that all valve actuators be
cycled approximately every 60 days or as required by the manufacturer of the actuation system. Any spare parts for
the valve shall be stored in the original packaging and under the same conditions as the valve will be stored. For
storage greater than 4 months, the storage container should be inspected every four (4) months to ensure it is in good
condition, and any additional protective coverings or materials are in working order. Ensure all parts are plugged,
and bare metal is covered with a suitable rust inhibitor.
SECTION VI
INSTALLATION
The valve must be installed so that pipeline stresses are not transmitted to the valve body. Despite its solid
manufacture, such stress may affect valve operation. If pipeline stresses are severe, they should be cushioned by
expansion joints or compensators. If supports are necessary for the valve, they should only support the dead weight
of the valve and should not serve as base points for the pipeline.
SECTION VII
STEPS OF INSTALLATION
7.1. All valve s must be in full closed position during installation or removal. It is not necessary to torque
seat the valve, but the disc travel must be restricted to prevent damage.
7.2. Please be sure there is no foreign material and that it is clean inside of the pipe and valve.
7.3. The shaft side of the disc is considered the high-pressure side of the valve, (as indicated on the
drawings by a flow arrow) meaning the best closure performance is obtained on this side of the valve, and a
determination as to the best installation should be made, to utilize this feature. This may not necessarily be
the normal flow direction of the system. (Fig.3).
7.4. Please install the valve stem horizontally as (Fig.4), thus could prevent sand and some chips from
collecting around bottom bushing and seat. Such reside could damage the valve.

4.5. Install valve and gaskets into pipeline as (Fig.5).
Flow Control Division
Fig 5
4.6. Make sure that the valve is installed concentrically between the flanges in order to could
prevent the disc from being damaged by interference with the flange and pipeline (Fig.6)
4.7. The typical installation for a butterfly valve connected to an elbow would be to align the
shaft axis to allow equal flow on each side of the shaft, minimizing dynamic torque requirements
for the valve. (Fig.7)

FLANGE CONNECTING & BOLTING
8.1. Keep valve protection boards until installation.
8.2. Make sure the material and size of gaskets could be suitable for the service. Ensure that the faces of flange and
valve are smooth and flat. Sandpaper the faces if there are any defects.
8.3. Check that all the bolts and nuts are in good condition.
8.4. Apply lubricant such as Molybdenum to all the bolts and nuts before fixing them.
8.5. The pipe support(s) may now be required to be partially disengaged. A determination as to pipe flange
alignment and space between the pipe flange and the valve face must be made at this time. The optimum spacing
would be such as to only allow the flange gasket to be installed, at the maximum, and the flange bolt holes would be
concentric.
8.6. The opposite connecting pipe flange face may not be more than 1/4 inch away from the valve flange face.
Alternate methods of alignment, other than using the flange bolts, must be utilized to conform with this requirement.
8.7. Install all studs, maintaining uniform clearance between the studs and the mating bolt holes. Additionally the
studs spanning the valve assembly should not contact the valve body.
8.8. Seat the flange by alternate tightening of four equally-spaced flange bolts no more than 1/4 turn per bolt, until
the flange faces seat. During this operation, it is advisable to continually check the relative distance between the
flange faces. Torque the bolts to approximately 25% of the final torque value (see table 1).
8.9. Inspect the remaining bolts and assure correct alignment. Tighten to the same level as the first four bolts.
8.10. Complete the tightening of all flange bolting in a minimum of four increments to the final determined torque
value.
8.11. Test cycle the valve to be sure that there is no interference or binding.

REMOVAL PROCEDURE
To remove your valve from the pipeline, please follow these simple steps:
Ensure that the valve is in the closed position.
Ensure that the line is depressurized.
Use protective clothing and equipment to prevent injury.
If your valve is equipped with a fail-open actuator, manually close the valve or disconnect the actuator then close
the valve before removal.
Attach nylon slings to the body shoulders of the valve and around the body of the actuator.
Remove the bolts holding the valve to the pipeline flanges.
SECTION X
LUBRICATION SCHEDULE
Flowserverecommends that your valve be inspected at least every three months to determine lubrication and other
maintenance requirements dependign upon your specific service conditions.
SECTION XI
STUFFING BOX MAINTENANCE PROCEDURE
Routine maintenance of the stuffing box consists of tightening the packing gland periodically. If leakage around the
stuffing box is discovered, first tighten the hex-nuts on the gland follower (more than 2/3 compression) as this may
reduce packing life. If the leakage still persists, replace the packing according to the following procedure. (For
clarity, the actuator and bracket are not shown in the following diagrams. It is not necessary to remove the actuator
or bracket before performing this procedure).
11.1 In order to gain access to the packing, remove the gland follower and slide it up to the actuator. See the diagram
below:

Page 9
Flow Control Division
11.2 Remove all of the packing in the stuffing box using a flexible screw hook. For stuffing boxes that
contain a lantern ring, use a puller with 10-32 threads to remove the lantern ring. Save the lantern ring for
reuse, but discard the other packing material. Please replace all the gland packing no matter the gland
packing is made of Graphite. (Fig.11)
Fig.11
11.3 Inspect the drive shaft, bore of the stuffing box, and the gland follower. These surfaces should be relatively
scratch free. If there is any damage, polish the surface to 32 rms finish (Fig.13). If any part has severe damage,
contact your Flowserve representative..

11.4 Install each new ring of packing, use the gland
follower to push each ring of packing evenly into
position after starting it in the stuffing box bore.
Stagger the splice-joints of each packing ring so they
are as far as possible from each other (see example
above). Usually, rotating each ring until the splice is
at 90° from the previous splice is sufficient. (Fig.14)
Fig 14
11.5 Install the gland follower and tighten it to firmly seat the packing. DO NOT compress the gland follower too
much. Over-tightening may dramatically reduce the life of the packing and may make it more difficult to operate the
valve. The maximum torque of the gland screw as below,

TROUBLESHOOTING GUIDE
In the event of valve difficulties you may try the following procedures before contacting Flowserve. If your
valve doesn’t operate properly before or after trying these trouble- shooting ideas, you may contact your
Flowserve representative for assistance
.
16.1 LEAKAGE FROM STUFFING BOX
If leakage around the stuffing box is discovered, first tighten the nuts on the gland follower to stop the
leakage. Do not over tighten the gland follower (more than 2/3 compression) as this may reduce packing
life. If the leakage still persists, replace the packing according to the procedure in the “ Stuffing Box
Maintenance Procedure” section.
16.2 LEAKAGE BETWEEN SEAL RING AND SEAT
Inspect Seal Ring for damage or excessive wear. If necessary, the Seal Ring may be lightly hand
polished using wet 400grit sandpaper. If leakage persists, or if not damage is evident, open and close the
valve 4 to 5 times, shutting it TIGHTLY each time. Re-check for leakage. If the valve still leaks in this
area, strike the back of the disc near the perimeter with a lead bar (or similar soft headed instrument to
prevent damaging the disc) to firmly seat the disc. Be sure to apply the force in a direction that will assist
in closing, not opening the disc. If leakage in this area persists, check the Seal Ring for roundness. If the
Seal Ring is out of round greater than its diameter times 1.00 x 10-3 (D x 0.001), orient the seal ring with
the longest dimension perpendicular to the valve shaft, and re-test for leakage. If leakage still preexists,
contact Flowserve for repair. (Fig.22)
16.3. LEAKAGE BETWEEN SEAL RING RETAINER AND SEAL RING (19) OR DISC
Firstly, ensure the bolts of retainer (20) were tightened in a diagonal sequence. If leakage persists, please
disassemble the retainer (19) and inspect the gasket (17). If found to be damaged, please replace the
gasket. (Fig. 22)
Fig.22
16.4. LEAKAGE BETWEEN BODY SEAT AND BODY (LOCKED DESIGN).
Firstly, ensure the bolts of body seat (22) were tightened in a diagonal sequence. If leakage persists, please
disassemble the body seat (23) and inspect the gasket (21). If found the damage, please replace the gasket. (Fig. 22)
