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.

Check correct performance of the valve by pushing the disk (part.8) in the direction of the

flow and making sure it goes back to the original position once it is released. If this is not the

case, check if there are foreign particles inside the valve and repeat the whole operation. If

the disk does not slide smoothly, valve must not be installed.

It is recommended to perform this task under qualified professional surveillance.

3.2) Valve Installation

- Threaded ends valve (DIN 11851)

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.

Place the joints (art. 2957-Genebre) between the ends to keep them tight and join them

together with a nut (art. 2954-Genebre).

- 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 can only be placed in vertical position (ascendant fluid).

Valves do not have to support pipe's efforts so it is advisable to anticipate a good

alignment and parallelism of such pipe.

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 check valves provide a leak proof lock when used adjusted to the pressure and

temperature values for which they have been designed.

•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.

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) Loosen and remove the Quick Locking (pos.8).

b) Separate the cover (pos.2) from the Body (pos.1).

c) Remove the gasket (Pos.3)

d) Remove the Stem guide (Pos.4)

e) Remove the spring (Pos.5) and disc (Pos.7) with the seat (Pos.6).

f) Remove the seat (Pos.6) from the disc (Pos.7).

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.6) in the disc (pos.7).

b) Put the spring (Pos.5) in the stem and later in the Stem guide (Pos.4).

c) Put the stem assembly inside of the body (Pos.1).

d) Put the gasket (Pos.3) in the body.

e) Put the Cover ((Pos.2) on the gasket

f) Put the Quick Locking (pos.8) joining the two parts (Pos.2 and Pos.1).

g) Adjusting the Quick Locking handle.

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
