1. Product description
Genebre, S.A. offers a wide range of valves designed and assembled to handle and drive
fluids.
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 behaviour when working conditions do not exceed pressure and temperature limits
(pressure curve) for which they have been designed. Please, refer to the product datasheet.
Art. 2120 / 2120D: Ductile Iron Butterfly Valve with EPDM seal.
Art. 2120: Grooved ends for use in pipes according to ASTM / ASME standard.
Art. 2120D: Grooved ends for use in pipes according to DIN standard.
Note: Some pipe diameters are the same between both standards.

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.
The responsibility for the safe use of these products lies with the user in
accordance with the provisions of these instructions for use as well as the specific
technical documentation of the device supplied!
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 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.
4.2) Installation of valves with grooved ends
Do not disassemble these valves for installation.
Make sure the pipe's and edges of the valve are clean.
Use the corresponding accessories for install the valve to the pipe (grooved coupling)
Make sure the coupling joints are well placed.
Make sure the pipe ends and the valve ends are compatible according to the outside
diameters (according to standard).
After assembling, check the tightness and performance of the valve.

REMARKS:
- Gate Valves, ref. 2120 / 2120D are designed according to API 609 to be
assembled with grooved coupling according to AWWA C606 at a maximum
working pressure of 300 PSI.
- It is recommended the use of filters in the pipe to make the valves longer life.
- Any damaged paint/coating during installation must be immediately repaired.
5. Operation instructions
5.1) Usage
Butterfly valves art. 2120 / 2120D provide a leakproof seal when used adjusted to the
pressure and temperature values for which they have been designed.
Seat material for the valve, joints, body, disk and axis have to be fully compatible with the
fluid circulating through the valve. Otherwise, valve could be seriously damaged.
This valve is suitable for use in fire protection system.
5.2) Manual operation
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 in line with
the pipe, valve is open.
For the valves operated with gear operator (≥10”/ DN250), the quantity of turns to be done
for a complete operation cycle of the 90-degree valve will be conditioned by the transmission
ratio of the gear box. Turn clockwise for closing or turn counterclockwise for opening the
valve.
6. Maintenance operations
Butterfly valves are designed so that they do not need any lubrication and/or periodical
maintenance during their life cycle.
However, periodical checks explained below will be useful to extend the service life of the
valve and reduce installation problems:

- Close the valve –from position completely open to completely closed.
- Verify all locks and threaded ends to check if they are loose or with rust. Tighten them if
necessary.
- Inspect the valve and surrounding areas to verify if there is any leakage in the stem or in the
flange connections.
7. Repair 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.
8. Hygiene and Safety Instructions:
8.1)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.
8.2) Before removing a valve from a pipe, check always if the line is completely drained and
depressurized.
8.3) Any type of repair or maintenance should be performed in ventilated places.
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
