1. Product description.
Genebre, S.A. offers a wide range of valves designed and assembled to handwheel and
drive fluids in industrial procedures.
The compatibility of materials used to build the valves (see technical specifications) and
the application of valves to the different industrial processes is at user's risk. Valves will
have an optimal behavior when working conditions do not exceed pressure and
temperature limits (pressure curve) for which they have been designed.
2. Transport and Storage conditions
Transport and storage of this kind of products must be done keeping them in their
original package!
VISUAL INSPECTION
Check whether during transport, unloading and placement the products have suffered
damages.
During storage it is recommended to keep them into the included protective wrapping to
avoid damages or dirt accumulation in the inside part of the valve.The wrap must not be
removed until valve is to be installed.
Valves must be stored in a dry and clean environment.
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.
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 products, according to present
instructions for use and specific technical documentation of the device.

3. Installation instructions
3.1) 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 the correct performance of the valve by turning the handwheel both sides (close
and open) and observing if the disc or needle slides correctly. If this is not the case,
check if there are foreign particles inside the valve and repeat the whole operation.
3.2) Assembling
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 into the pipes' thread ends and
thread the valve being careful not to excessively tighten the conical threaded ends.
Do not use valve's handwheel as a lever to thread the valve into the pipe.
To tighten the valve into the pipe it is recommended to use a spanner or monkey wrench
only on the hexagonal area of the valves edges or in the body central assembly; the force
applied needs to be less than 30 Nm.
If possible, it is recommended to install the valve in horizontal position and the handwheel
upwards.
Valves do not have to support pipe's efforts so it is advisable to anticipate a good
alignment and parallelism of such pipe.
It is also recommended to use filters in the pipe to extend lifecycle of the valve.

4. Operating instructions
4.1) Usage
GENEBRE valves provide a leakproof lock when used adjusted to the pressure and
temperature values for which they have been designed.
Valve materials have to be fully compatible with the fluid circulating through the valve.
Otherwise, valve could be seriously damaged.
4.2) Manual operation
When operating the valve you must avoid excessive lateral efforts with the handwheel.
To close, the operation consists in turning the handwheel clockwise and anticlockwise if
you want to open the valve.
5. 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.
5.1) 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 operate it for control purposes every six
months.
5.2) Verify possible leaks in the stem area; in case they exist, proceed to tighten the
gland nut. If leak persists, valve should be replaced (see section 6).
5.3) Verify possible leaks through the line (due to closure); this defect is probably caused
by deposition of impurities between the disc or needle and the seat, transported by the
fluid. Disassemble the valve from the pipe, clean it thoroughly and reinstall it. If the
problem persists you should change the valve, since it is possible that some metallic
parts used for closure are damaged (erosion, corrosion). See section 6 for further details.
6. Reparation instructions
These types of valves, due to their assembling specifications are not worth repairing,
because most of the times are simply not cost-effective, so we recommend to directly
replace them.

7. Hygiene and Safety Instructions
7.1) Fluid passing through a valve or accessory can be corrosive, toxic, flammable or
pollutant. When operating valves, you must follow the security instructions and it is
recommended to use personal protection gadgets:
1) Protect your eyes.
2) Wear gloves and appropriate working clothes.
3) Wear safety footwear.
4) Wear a helmet.
5) Have running water at hand.
6) To operate flammable fluids, make sure you have an extinguisher at hand.
7.2) Before removing a valve from a pipe, check always if the line is completely
drained and depressurized.
7.3) Operate the valve in open position to make sure there is no pressure in the internal
cavity.
7.4) Any valve being used by toxic services department needs to obtain a cleanliness
certificate before being operated.
Before disassembling the pipe's valve to clean or replace it, make sure that line
has been closed and depressurized because a bad operational procedure could
cause a serious accident to staff and installation system
Before installing new valve, check if it meets the requirements of the valve
being replaced
