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.

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
