PRODUCT DESCRIPTION
1 1/2” flushing valve for flush-mounted toilet for low pressure and pressurised
circuits, suitable for use from 015 bar to 5 bar, designed to work efficiently with
water tanks at 1.5 m in height above it or more, as well as pressurised circuits.
15 discharge litres at 3 bar, (8 seconds duration) adjustable flow rate.
8 discharge litres at 0.25 bar, (10 seconds duration) adjustable flow rate.
Option to regulate the water flow rate by discharge.
Includes a full water flow shut-off system.
The valve can be directly installed using its 1 1/2” thread and its 1 1/2” thread output,
or with one of the supplied adapters, metal for welding with copper pipes or techno-
polymer for plastic pipes.
Includes a plastic protector to facilitate the valve’s installation and protect it until the
plate and push-button are installed.
Repairing the valve is very straightforward and spare parts are available.
Three types of plates can be combined with our valve: PA1051, PA1052, PA1054.

RECOMENDED INSTALLATION
The GENEBRE flushing valve can be used in
very low pressure circuits with water tanks
or pressurised circuits.
With the aim of preventing unwanted noise,
the installation of a pressure reducer or
intermediate tanks is advised above 2.5 bar
or 25 meters of water column.
For tank installations with horizontal piping
of up to 4 meters in length, it must have
a minimum diameter of 1 1/4” in order to
supply one single valve, and a minimum
diameter of 1 1/2” to supply more than 1
valve or above 4 meters in length. Please
note that exceeding 10 meters in length in
the horizontal section is not advised.
Always install curves and avoid T-type
branches for minimum load losses (do not
install elbows)
Our valve has an input thread of 1 1/2” which
can be used directly or reduced in the case
of using water columns exceeding 10 meters
or pressures exceeding 1 bar.
It is advised to install a maximum of 4 valves
per supply line.
We advise the use of independent supply lines for flushing valves and the
remaining installed taps, as please note that using the valve may cause a drop in
water pressure in the cold water circuit, which could cause a sharp rise in
temperature in mixed taps in use.
The installation must be correctly sized (see tables) in order to ensure efficient
discharge.

The GENEBRE discharge valve is supplied with a plastic
lid which protects it during the installation process.
Please do not remove until the tiling is complete and
proceed to install the push-button.
The valve can be directly installed using its 1 1/2” thread and its 1 1/2” thread output,
or with one of the supplied adapters, metal for welding with copper pipes or techno-
polymer for plastic pipes.

Prior installation of the valve insures that piping is free from foreign bodies like
Teflon, hemp, stones, etc. It is advised to previously purge the installation in order to
remove remains that could damage the valve.
When installing the valve please note the maximum and minimum depth indicated
on the plastic protector, and the final finish (tiles) must be within these limits.
Please note the maximum installation height.

Please check the circulation direction of the
water indicated by the arrow marked on the side

When tiling cut the tiles that are
touching the protector.
Mount and adjust the adjusting screw
on the stem of the value, leaving
a tolerance of 1 mm to 2 mm between
the adjusting screw and the push-button
on the plate.

Leave the adjusting key in the horizontal
position to facilitate the installation of
push-button PA-1051.
Adjust to the desired flow by using the adjusting handle, to increase or decrease the
discharge volume or completely close the valve.

Closed position
Please observe a cross-section of the valve in the
CLOSED position.
We can see that the water is in the area above it and
retained by the closing O-ring located on the piston
body, and the decompression O-ring located on the
shaft.
The push-button is at rest, it outcrops over the plate
and the spring is decompressed.
Open position
Please observe a cross-section of the valve in the
OPEN position.
By pressing the push-button we move the shaft and
hence the body of the piston, decompressing the
chamber of the vessel and opening to let the water
flow by separating the closing O-ring located on the
body of the piston.
The push-button is flush with the plate and the
spring is compressed.
From this position the spring and the internal
pressure of the POM vessel cause the piston
body to displace towards
the exterior, returning to
the initial position.

The displacement will be controlled by the vacuum caused
inside the POM vessel and the lip seal. Through the POM
vessel’s groove, water will enter its chamber until it returns
to its initial position.
