2) Storage
During storage it is recommended to keep the product in the included protective wrapping to
avoid damages or dirt accumulation. The wrap must not be removed until element is to be
installed. As much as possible, it must be stored in a dry and clean environment.
Transport and storage of these devices must be done in their original wrapping.
VISUAL INSPECTION
Check whether during transport, unloading and placement, devices have suffered no damages.
MECHANICAL INSPECTION
Check whether all mobile parts of the different devices, as well as the screws and other elements, are
accomplishing their purpose.
If you notice any kind of anomaly during reception of the goods, contact immediately
with GENEBRE in order to determine the possible responsibilities on the issue and make the
devices fully operational.
IMPORTANT NOTE:
Before installing and/or manipulating these elements, READ CAREFULLY these
instructions for use and OBSERVE all contained information. If you fail to
understand any of their content, please contact GENEBRE, S.A.
User is responsible for the safe use of these devices, as established in present
instructions for use and in the specific technical documentation of the device.

3) Installation instructions
3.1) Preparation
Remove any remains of packaging from the actuator.
There might be serious problems caused by valves installed in a dirty pipe.
Make sure the pipe is free of dirt, welding particles, etc. before installation, since the valve
might suffer irreparable damage when the equipment is turned on → prepare a clean
working area.
Plan enough space for future maintenance operations.
It is recommended to perform this task under qualified professional surveillance.
3.2) Valve Installation
- Threaded ends valve
Do not disassemble the valves to install them.
Make sure the valve's pipe and thread ends are clean and are compatible one with another.
Do not use the valve handle as a lever to screw the valve into the pipe.
- Clamp ends valve
It is not necessary to disassemble the valve in order to install it.
Make sure the pipe’s clamp and the cover (pos.2) clamp are clean. Place the silicone joints
(art. 2987-Genebre) between the clamp ends to keep them tight and join them together with
a quick locking binding clamp (art. 2986-Genebre). There is a different joint and binding for
each valve size.
- Welded ends valve
a) Before weld the valve disassembling it as indicated in the Section 6.1.
b) Weld the connections (pos.1) to the pipes. All components must be stored in a dry and
clean environment.
c) When cold, clean the edges' locking surfaces and then assembly the valve as indicated in
the Section 6.2.

¡The welding work must only be carried out by properly qualified personnel!
IMPORTANT INFORMATION:
Design of this type of valves allows us to install them in any position as they are
bidirectional, so the direction of fluid flow does not matter.
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 performance and to check if there is any obstruction in the disc that prevents it
from closing.
4) Operational instructions
4.1) Usage
Before starting the equipment you have to read the Technical Specifications and never
exceed the limit values.
Never touch the valve and/or pipes in contact with surrounding fluid when the process is
started; you can suffer from injuries such as burns.
The butterfly valves provide a leak proof lock when used adjusted to the pressure and
temperature values for which they have been designed.
4.2) Manual operation
Actuator and valve are composed by mobile parts, either rotary or sliding; do not approach
your fingers to these areas as you can get seriously injured.
When operating the valve you must avoid excessive lateral efforts with the handle.
To close it, you must turn the handle 90 degrees clockwise. When the handle is inline with
the pipe, valve is open.
In case you need to remove the handle to automate the valve, the stem (pos.2) has a
mechanized linear mark at the front part that allows us to know its current position (opened or
closed).

4.3) Remote operation
When automation valves are required, GENEBRE S.A. can provide a great variety of
pneumatic actuators, electric actuators, electropneumatic and electronic positioners to cover
a large range of operations.
•The operation in extreme temperature conditions exceeding the design limits may damage
internal and external parts, and it might be potentially hazardous for the operating or
maintenance personnel.
•The operation in extreme pressure conditions exceeding the design limits may cause a
malfunction and the spontaneous breakage of parts and, therefore, might be potentially
hazardous for the operating or maintenance personnel.
5) Maintenance instructions
Frequency, location 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 open or closed position for a long period of time. It is
recommended, if the process allows for it, to proceed to an operational task for the valve
every six months.
6) Reparation instructions
Genebre, S.A. will not be held responsible for an inappropriate operation of the element or its
components.
¡Use only components/spare parts original or recommended by GENEBRE, S.A!
6.1) Disassembling
Prepare a clean working area and adequate tools to perform mechanical tasks.

a) Remove the plugs (pos.6 y 11).
b) Loosen the screw (pos.10) and remove the entire handle (pos.8 / 8a).
c) Loosen and remove the screws and nuts (pos.4 y 5)
d) Separate the connections (pos.1).
e) Remove the disc (pos.2) with the seat (pos.3).
f) Remove the seat (pos.3) from the disc (pos.2).
6.2) Assembly
Before proceeding to reassemble the valve, make sure that reparation kit and/or pieces to be
used are appropriate and original from the factory.
When it is assembled again, cleaning is essential for a long life for the valve.
a) Put the seat (pos.3) in the disc (pos.2), lubricate the seat and disc with soapy water for
help to install.
b) Put the seat in open position (pos.2) for facilitate the assembly of the valve.
c) Put the disc and seat assembly between the two connections.
d) Put the screws (pos.4) and the nuts (pos.5) adjusting slowly and alternating diagonal,
check that the seat is positioned correctly (see the recommended tightening torque in
Section 6.3).
e) Put the entire handle (pos.8 / 8a) in open position and put the screw (pos.10).
f) Put the plastic plugs (pos.6 y 11).
Once installed, it is recommended to open and close it a couple of times to verify its
good performance and to check if there is any obstruction in the disc that prevents it
from closing.
6.3) Tightening torque Screws/ Nuts for joining the valve's two parts:

Before removing the valve from the pipe for cleaning or substitution, make sure
the line has been closed and depressurized, since the wrong handling might
cause a serious accident as well as serious damage to the equipment
