4. Installation instructions
4.1) Preparation
Remove any material remains of the valve wrapping.
Serious problems may arise with the installation of a valve in a dirty pipe.
Make sure the pipe is not dirty and doesn’t have welding particles, for example, before
installing it. This may cause irreparable damages in the valve when the equipment is
started → prepare a clean working area.
Plan beforehand enough space for future maintenance operations.
Control correct operation of the valve by turning the handle clockwise and making sure
the ball closes the fluid flow. If this is not the case, check if there are foreign particles
inside the valve and repeat the whole operation.
In case of vibrations in the pipe it is strongly recommended to mount anti-vibration
elements to absorb them. Otherwise, the life of the product could be drastically reduced.
4.2) Assembling
- Art. 2040 / 2041 (valve with threaded ends)
Make sure the valve's pipe and thread end are clean and are compatible one with
another (type of thread end) Apply an appropriate sealing in the pipes' thread ends and
thread the valve being careful not to excessively tighten the conical threaded ends.
Do not use valve's handle as a lever to thread the valve into the pipe.
To tighten the valve it is recommended to use a spanner or monkey wrench only on the
hexagonal area of the valves edges, the torque applied being less than 30 Nm.
- 2540 (E) / 2541 (E) / 2544 / 2545 (valve with threaded ends)
Do not disassemble the valves for their installation.
Make sure the pipe's and edges flanges of the valve are clean.
Use the corresponding screws in all of the flanges drill holes.
Place an adequate joint in each end and align it in the center of the flanges.
Tighten screws evenly and cross-shaped to avoid deformations. To do so, you must not
force in any case the pipe to center the valve; it should take its position smoothly. Last,
verify that screws are tightened with the recommended torque for each type of screw.
Make sure the flanges' joints are well situated.
After assembling, check the tightness and performance of the valve.

IMPORTANT INFORMATION:
The design of this type of 3-way ball valves with four seats allows us to install
them in any position as the fluid entrance can be any of the three.
If possible, it is recommended to install the valve in horizontal position and the
stem (handle) upwards.
Valves do not have to support pipe's efforts so it is advisable to anticipate a good
alignment and parallelism of such pipe.
Once installed, it is recommended to open and close it a couple of times to verify
its good knowledge and to check if there is any obstruction in the ball that
prevents it from closing.
It is also recommended to use filters in the pipes to extend lifecycle of the valve.
5. Operating instructions
5.1) Usage
Ball valves provide a leakproof lock when used adjusted to the pressure and temperature
values for which they have been designed.
Avoid by all means leaving the valves in partially open position if you are not aware of the
pressure drop and flow rate in that position, as the service life of the seat can be reduced
and/or it can be damaged due to the ball bore valve.
Seats for the valve, joints, body, ball, stem and ends have to be fully compatible with the
fluid circulating through the valve. Otherwise, the valve could be seriously damaged.
Torques required to operate valves are listed in the table Torques to activate the valves
(see Section 8.1).
5.2) Manual operation
When operating the valve you must avoid excessive lateral efforts with the handle.
In case you need to remove the handle to automate the valve, the stem (part 5) has a
mechanized linear mark at the front part (“L”or “T”shape) that allows us to know its
current position.

5.3) Remote operation
When automation of the valves is required, GENEBRE S.A. can provide a great variety of
pneumatic actuators, electric actuators, electropneumatic and electronical positioners to
caps a large range of operations.
6. Maintenance instructions
Frequency, place and process of maintenance will be determined by the user by taking
into account usage of the product. However, periodical checks explained below will be
useful to extend the service life of the valve and reduce installation problems.
Valves must not remain in the same position for a long period of time. It is recommended,
if the process allows for it, to operate it for control purposes every six months.
6.1) Stem leaks
Remove the handle or actuator, the lock nut washer (part 14-Threaded / part 1-Flanged)
and tighten the nut (part 13-Threaded / part 12 Flanged) of the stem packing (see Section
8.2). If the leakage persists, valve should be disassembled to replace the stem washers
(parts 7,8,9,10-Threaded / parts 6, 7, 8, 9-Flanged).
See reparation instructions.
6.2) Body/Cap gasket leakage
- Art. 2040 / 2041 (valve with threaded ends)
Check if the caps (part 2) is tight. If it was loose, tighten it. If leak continues, it is probably
due to a damage int he body's joint or the locking surface, and it will be necessary to
disassemble the valve to repair it.
See reparation instructions.
- Art. 2540 (E) / 2541 (E) / 2544 / 2545 (valve with flanged ends)
Check if the body screws (part 21) are tightened. If they were loose, adjust them up until
the recommended torques (IMPORTANT: adjustment of such screws will have to be
done at room temperature). If leak continues, it is probably due to a damage int he body's
joint or the locking surface, and it will be necessary to disassemble the valve to repair it.
See reparation instructions.

6.3) Leakage in the line (through seats).
Check if the valve entrance is in a completely closed position. If so, the leak is due to a
seat or locking surface being damaged and it will be necessary to disassemble the valve
for repairing it.
See reparation instructions.
7. Reparation instructions
7.1) Disassembling

It is convenient to match one of the nut vertex with one of the stem vertex to be able to
place later on the lock nut (part 14).
Note that if the nut is too tight, the rod torque will increase and service life of its elements
will be reduced.
c.- Place one of the seats (part 4) in the inside part of the body and the other three seats
in the caps's location.
c.- Place the stem in closed valve position and insert the ball (part 3) inside the body
cavity (part 1) matching the ball slot with the stem milling (part 5).
e.- Place the corresponding seat holders (part 20) on each one of the valve's stoppers
(part 2).
f.- Place the stoppers on the body and tighten them as much as possible.
It is required that the body and caps make contact in their metal sides.
- Art. 2540 (E) / 2541 (E) / 2544 / 2545 (valve with flanged ends)
a.- Place a new friction washer (part 6) on the stem (part 5) and also the o’ring (part 7) in
its stem corresponding location, lubricate the stem with a thin layer of grease or silicon
(for example, Dow Corning 200) and insert it in the valve's body (part 1), in the internal
cavity, by pushing a bit to fix it.
b.- Place a new packaging (part 8) into its location in the upper cavity of the body (part 1),
the washer (part 9) the gland nut (part 10) and the spring washers (part 11 ) with external
borders together (concave position). Place the nut (part 12) and tighten it. Make the stem
turn a couple of times and readjust the nut respecting the torque specified value (See
Section 8.2).
If necessary, fasten with a wrench the internal body of the stem to tighten properly the nut
without making the stem turn.
It is convenient to match one of the nut vertexes with one of the stem vertexes to be able
to place later on the lock nut (part 13).
Note that if the nut is too tight, the rod torque will increase and service life of its elements
will be reduced.
c.- Place the stem in closed valve position and insert the ball (part 3) inside the body
cavity (part 1) matching the ball slot with the stem milling (part 5).
d.- Place each one of the seats (part 4) on its corresponding location.

e.- Terminals or caps (part 2) need to have locking parts cleaned before proceeding to
final assembly. Place each one of them in their corresponding position using the caps's
joints (part 18).
f.- Then, proceed to place the screws (part 21) adjusting slowly and alternating diagonal
and evenly until obtaining the recommended tightening torque (see Section 8.3).
