THIS DOCUMENT PROVIDES THE INSTRUCTIONS FOR
THE INSTALLATION, USE AND MAINTENANCE OF THE
VALVE, THEREFORE IT IS AN INTEGRAL PART OF THE
VALVE ITSELF AND MUST BE READ CAREFULLY BEFORE
ANY USE AND KEPT WITH CARE.
STRICTLY COMPLY
CONTAINED IN THIS DOCUMENT IN VIEW OF A SAFE AND
EFFECTIVE USE OF THE VALVE.
FAILURE TO COMPLY WITH THESE INSTRUCTIONS
MIGHT CAUSE EARLY
SITUATIONS OF DANGER, IN ADDITION TO VOIDING ANY
WARRANTY.
1- GENERAL INFORMATION
1.1- The RV3 pressure regulator is a manually-adjustable,
pressure-operated device which, according to its setting, limits
the pump/system pressure by conveying the excess of water to
the by-pass.
Moreover, when the outlet flow is blocked, this device totally
releases the flow, thus keeping the pump/system at the adjusted
pressure.
1.2- Since the RV3 valve is used in connection with a high
pressure water pump/system, which shall be called hereafter
only "system", installation and use must be suited to the type of
system used and comply with the safety Regulations in force in
the Country where the valve is used.
1.3- Before using the valve, make sure that the system the valve
is used with is certified to comply with the relevant Directives
and/or Regulations.
1.4- Before installing and using the valve for the first time, we
suggest you check that it is undamaged and make sure that the
rated features correspond to the required ones. If this is not the
case, do not use the valve and contact the after-sales service of
Interpump Group for information.
1.5- In order to install the valve correctly, follow the instructions for
the water inlet, outlet and by-pass connections, as stated in this
instruction manual and/or on the valve itself.
2- PACKAGE
2.1- Packages must be handled in compliance with the
instructions stated on the packages themselves and/or provided
by the manufacturer.
2.2- In case the valve is not used immediately, it must be stored
in its integral package and placed in areas which are not
exposed to the weather and protected from excessive humidity
and from direct sunlight. Moreover, it is advisable to place
wooden pallets or other types of pallets between the package
and the floor, in order to prevent the direct contact with the
ground.
2.3- The package components must be disposed of in
compliance with the relevant laws in force.

3- INSTRUCTIONS FOR PRESSURE SETTING:
3.1- In order to obtain a correct adjustment and consequently a
proper functioning of the valve, always make sure that, when
working at the maximum pressure, the valve by-pass keeps
releasing a quantity of water equal to 5% of the total flow-rate. In
case the flow-rate at the by-pass is close to zero or exceeds
15% of the maximum flow-rate, this could cause faults, early
wear and result in situations of danger.
The positions mentioned in the following instructions refer to
IN
those shown in the spare parts catalogue (page 4).
3.2- Connect the valve to the water system and follow these
steps:
3.2.1- Unloose the nut pos. 2.
3.2.2- Unscrew the screw pos. 1 in order to completely release
the springs.
3.2.3- Open the gun or the water control device and start the
system. Make sure that the air contained in it is fully ejected.
3.2.4- Keeping the gun or the water control device open, start
adjusting the pressure by screwing down the screw pos.1.
Alternate the adjusting operations with a few openings and
closings of the gun or of the control device. When the desired
pressure has been reached, open and close the gun/control
device a few times again in order to stabilize the various
components (seals, springs etc.). Check the pressure value
again and correct if necessary.
3.2.5- Screw down the nut pos. 2 up to contact with the body, in
order to lock the screw pos. 1.
3.2.6- In order to obtain working pressures lower than the
maximum set pressure, unscrew the screw pos. 1.
In case of doubts, do not hesitate to contact the
after-sales service of Interpump Group.
IMPORTANT: During use, never exceed the
maximum values of pressure, flow-rate and
temperature as stated in this document and/or
indicated on the valve.
4- WARNINGS
4.1- The installation and the setting of the maximum pressure
must be made by qualified staff only, who must have the
required skills to handle high pressure systems and be informed
of the operating and safety instructions contained in this
document.
4.2- The installer must provide the ultimate consumer with the
proper instructions for the correct use of the system the valve is
used in connection with.
4.3- Use soft and filtered water only. In case of salt water
and/or of water containing solid particles of a size exceeding
360µm, the internal components of the valve will be subject to
quick wear; furthermore, this might compromise the correct
functioning of the valve. Addition agents can be used in the
