SAFETY INSTRUCTIONS
–Do not operate in the area of action of the system without being protected by suitable
protective goggles and clothing;
–Do not carry out operations without disconnecting the P.T.O. (stop the pump);
–Install adequate protection guards for all moving parts such as the shaft, pulleys, couplings,
etc;
–Do not remove the guards for the moving parts;
–Do not modify the control installation conditions and in particular do not modify the mounting
and hydraulic connections;
–Do not operate any taps not connected to a usage which may prevent accidental leakage of
the liquid being pumped;
–Make sure that there is safety valve of adequate capacity in the delivery circuit, in addition to
the pressure regulation valve;
–Make sure that the hoses are properly fixed before use by checking all the connections;
–Carry out, before use, the checks as specified in paragraph 6.
–Protect the control against icing in the winter period.
–Never leave the control at rest with the pumped liquid inside. Persistence of liquid in contact
with the internal parts of the control, when not necessary, can cause the control to deteriorate
more quickly.
–Stop the pump and release the pressure from the pressure circuit before carrying out all
maintenance or checks;
–Always DISCONNECT supply cables during maintenance on the machine or during long
periods of non-use;
–Children and animals must be kept far away from the pump;

–Do not introduce:
•Aqueous solutions with density and viscosity greater than those of water;
•Inflammable liquids or liquefied gases;
•Chemical solutions for which there is not guaranteed certainty of their compatibility with the
materials of which the control is made;
•Water for food purposes;
•Any kind or type of paints and varnishes;

3
•Solvents and thinners for any kind or type of paints and varnishes;
•Fuels or lubricants of any kind or type;
•Liquids containing granules or solid parts in suspension.
- Before any maintenance:
•Always make sure that the system pump is not operating and that the motorization of the
drive is completely disconnected.
•Make sure that the entire hydraulic circuit is not in pressure; therefore, close the pump
suction, relieve the pressure of the hydraulic circuit.
•Make sure that electrical supply connection is disconnected and that the metallic body of
any drive mechanisms is isolated.
•Always remove the battery connection cables while it is being recharged.
•Do not carry out electric welding with the power wires connected; make sure that they are
both (+ and –) disconnected, in order to avoid uncontrollable voltage peaks.
- Before using the system:
oMake sure that the connection hoses of the circuit are properly fastened by checking the
connections.
oCarry out adjustment of the distributor before work, only with clean water, making sure that
the various joints and connections are not leaking.
oEvery time the tractor is started and stopped the general valve must be brought to the OFF
position (“by-pass”), in order to avoid inconvenient problems;
oIn order to avoid danger to persons or the environment, it must be washed with clean water
at the end of every treatment.

2. Product description
The spraying control units of Idromeccanica Bertolini are only applicable to the systems
driven by diaphragm or piston volumetric hydraulic pumps. They are suitable for sprayers
in agricultural field, atomizers, private and public hydraulic systems, fountains, etc.
The spraying control units are composed of motorized or/and manual electrical section
valves conceived and studied to overcome the traditional product problems ensuring
always high performances.
-The basic characteristics of those valves are:
-Non-deformable at high and low temperatures;
-Complete watertight seals;
-Free assembly position;
-Thermal protection against accidental circumstances;
-overtime duration;
-controllable with a simple bipolar switch;
-Single or parallel functioning;
-System versatility;
-No current absorption when adjusted.
The materials used are: high resistance plastic materials (polypropylene +Fiberglass),
stainless steel, and Viton gaskets and this makes them compatible with very aggressive
chemical solutions.
A motorized electric unit, modularly built in different configurations, each of them with
specific characteristics, according to the client’s need, is composed of section valves (until
7 max. sections), volumetric valve, adjustable pressure relief valve and main on-off valve.
The max working pressures, according to the technical characteristics of the components,
are: 20 bar or 40 bar.
The motorized valves are controlled by sprayer controls or by computer B.Matic 500 (all of
them supplied separately) and each of them is for DIN 43650-A/ISO4400 connections.
The voltage must be always:
12 VDC 2
0.5 A valve VV
12 VDC 2
1.5 A valves: VG, RS, RD
This is the normal voltage for a battery in the most common agricultural equipment.
Out of this field, you may incur functioning problems or damages to the internal electronic
circuit.

WARNING! For a correct
functioning, do not connect the
return hoses to the bottom of the
tank with the aim to use them as
hydraulic agitators, but connect
them exclusively to the top part
of the tank.
Use only components (hoses,
clamp, fittings, etc.), which
minimum characteristics are
equal to the max pressure of the
pump or the control; make sure
not to create throttling during the
course.

3. Identification and description of the components

8
•C: Position indicator, indicates, according to its colour, the ball position. The colours are
RED and GREEN.
•D: adjusting pressure relief valve knob. Unscrewing manually this part the maximum
pressure is increasing.
•E: compensating discharge adjustment knob. Unscrewing manually this component the
water coming back to the tank decreases, therefore pressure increases.
•M: Pressure gauge
All the control units made by IDROMECCANICA BERTOLINI S.p.A. are always fitted
with the VS adjustable pressure relief valve.
The adjustment of this valve is made by the operator, who must adjust the pressure
to a value that is higher than the maximum working pressure, but lower than the
maximum security pressure attainable by the hydraulic system.
ANYWAY THE MACHINE MUST BE PROVIDED WITH A SEPARATE SAFETY
VALVE, SET AT THE WORKING PRESSURE THAT IS NOT HIGHER THAT
10% OF THE MAX.PRESSURE OF THE HYDRAULIC SYSTEM.
Description of the functions
1. VS Pressure relief valve: It is adjusted manually by its knob (screwing it, pressure
increases, unscrewing it, pressure decreases).
It discharges into the tank the excess liquid when the adjustment pressure is obtained.
2. VG: Main ON-OFF ball valve: it opens or closes the discharge to the tank. The valve
position is showed by the indicator:
•“GREEN” position: discharge to the tank.
•“RED” position: working condition.
It is, for its function, always fitted after the VS valve, in order to use only one
discharge hose.
3. VV: volumetric adjustable pressure valve: It adjusts manually the spraying pressure,
if connected to a sprayer control or automatically if connected to a computer B Matic
500. In this case it provides to increase or to decrease pressure at variable driving
speed of the tractor, keeping the same amount of liquid per surface unit (ex.
Litre/hectare).
The liquid in excess is deviated to discharge.
The valve position is showed by the indicator:
•“GREEN” position: discharge to the tank
•“RED” position: working condition
The rotation of pin is not instantaneous but gradual; it can be 9 seconds (suggested for use
with computer) or 21 seconds (suggested for use with sprayer control).
4. RS section valve: it opens or closes the corresponding boom section; it discharges the
liquid in the tank by the VS valve or VG valve, if present.
The valve position is showed by the indicator:
•GREEN” position : closed boom (discharge in the tank)
•“RED” position: working condition (liquid to the boom)
5. RD section valve: The RD valve is a “deviating valve” that adjusts in by-pass the liquid
amount that you have established with reference to counter clockwise knob adjustment.
This implies a pressure variation if all of the section valves are not adjusted at the same
value (ATTENTION THE ADJUSTMENT IS VERY IMPORTANT).
If you want to increase the pressure to the boom the knob will be turned counter clock-

9
wise. If you want to decrease pressure you must turn it clockwise.
The section valve must be adjusted all the times that a different nozzle is used, so
the constant liquid distribution is ensured.
6. M Pressure gauge: it shows the working pressure when the VG main valve is closed
(red position showed by the indicator).
4. Installation
The control unit model must be chosen by the manufacturer, according to the
chemical product nature and the system features. Failure to follow this warning
can result in injury and/or property damage.
The sprayer manufacturer should take care of the proper selection and correct size of the
hoses and connections that must correspond to the dimensions of the recommended
fittings.
Be sure that the control unit is attached to a strong base plate and anchor it with bolts
sufficiently strong to hold it in place. We recommend to protect your control unit from the
bad weather and from the spraying effects during the treatment.
The hoses dimension should not be smaller than the control units’ pipe fittings diameter.
5. Hydraulic connections
•Connect the delivery hose from the pump to the INLET fitting (IN) ;
•Connect the return hoses to the tank for the unused liquid to the by-pass fittings (by-
pass);
•Connect the hoses to the boom to the delivery pipe fittings : they must be equivalent
(same number) to the boom sections or hydro-agitators , if any;
Failure to follow this warning can result in personal injury or environmental
damage and/or malfunctions of the control unit and consequently will void the
product warranty.

10
6. Control unit functioning and use
General checks before the use
•At every use, clean the filter on the control (if present) and every other filter present on
the system; this simple operation will help you to keep the system efficient and to carry
out the treatments in the best way possible.
•Close all pressure hoses connected to the nozzles or boom; an open nozzle can
cause serious damage to persons, animals or things in the vicinity.
•Check the state of the hoses each time the system is used; also make sure that all
connections are tight and secure.
•Check the state of connection cables and electrical connections each time the system
is used; also make sure that the batteries are charged optimally (for motorized versions
only).
•Inspect the control and its components periodically. Routine maintenance of the
system protects your investment.
•Make sure that when the pump is being started up, the general valve is kept in by-pass
position as indicated on the label.

7. Control valve maintenance
ATTENTION!
Before starting any maintenance operation or inspection of the control unit,
wash it first with pure water, then completely empty out all liquid contained.
Pay particular attention to the parking of the machine on which the control unit is
mounted, in order to avoid danger to you or those around you.
Never carry out maintenance with children nearby!
Protect hands, eyes and body with suitable clothing; the control unit could have
been used with chemicals that damage your health.
The control unit is made from inedible parts. Do not bite, suck, chew or ingest any
part of the control unit for any reason.
Protect the environment from the liquids contained in the control unit.
Clean up residues and dispose of them regularly; no residue must enter the
canalization network or the ground.
Attention! Bertolini electrical valves are designed in order not to be opened;
therefore, when necessary, always replace the complete valve. Opening or
tampering with valves by non-authorized personnel invalidates all terms of
warranty.
USING “ORIGINAL BERTOLINI SPARE PARTS”INCREASES THE LIFETIME OF
YOUR CONTROL UNIT, BY ALLOWING IT TO OPERATE IN THE BEST POSSIBLE
CONDITIONS.
In the case where the control unit has to be dismantled, it is advised to change the sealing
O-rings, since they could get damaged during this phase, causing leakage of liquid in the
various valves.
Routine maintenance of the distributor protects your investment.
During the functioning it is possible that with closed valves (red colour indicator) the liquid
is coming out from the boom, in this case it is possible that the ball and/or its gaskets are
worn.
•Ball and/or gaskets replacement:
Remove the flange of the ball, take out the ball and the gaskets and check wear.
Replace the necessary parts and reassemble.
The corresponding kit that must be ordered to IDROMECCANICA BERTOLINI, are the
following:
•Part N° 24.5334.97.3 →VG (40 bar), VV 39 (9-21 sec.) valves;
•Part.N° 24.5335.97.3 →VG (20 bar) valve;
•Part.N° 24.5336.97.3 →RS (40 bar), VV 27 (9-21 sec.) valves;
•Part.N° 24.5337.97.3 →RD (20 bar), RS (20 bar) valves;
•Part.N° 24.5338.97.3 →RD (40 bar) valve
•Wash carefully with water the internal parts of the distributor after each treatment.
•Disconnect voltage during any maintenance.

As a result of the normal wear of the nozzles it may become necessary to check their flow
rate and therefore their efficiency periodically. To do this, proceed as follows:
a. Take the system to working conditions.
b. Measure the flow rate (Q –litres supplied in one minute) of a nozzle using a graduated
container (Pict.17). Compare the values measured with the corresponding
measurements given in the charts provided by the manufacturer of the nozzles used.
If you wish to check the litres supplied per hectare (l/ha), insert the data in the following
formula:
Where:
Lh = applied volume (l/ha)
Q= nozzle capacity (l/min)
I= interspace between the nozzles (m)
V= advancing velocity (km/h)
If instead you need to know the required flow rate, insert the data in the following formula:
