3 FIELD OF APPLICATION
The 853 series electric valves are designed for use in the agricultural sector and can be used as ow switches in a system under
pressure for conveying liquids.
These valves are for professional use only.
4 LIMITATIONS OF USE
The 853 series electric valves may not be used:
- as safety valves;
- in systems where gases, vapors, or similar pass through;
- in systems for explosive atmospheres;
- in contact with foodstuff;
- in civil systems.
This device is designed to work on agricultural machinery for spraying and crop spraying applications.
The equipment is designed and manufactured according to:
- Directive 2014/30/UE and following amendments (EN ISO 14982 - Electromagnetic
Compatibility - agricultural and forest machines);
- Directive 2006/42/EC and following amendments.
5 SAFETY REGULATIONS
CAUTION: All installation and maintenance operations must be carried out by qualied
personnel with circuit not under pressure and without power supply (connector
disconnected).
ARAG IS NOT LIABLE FOR ANY DAMAGE RESULTING FROM INSTALLATION BY
UNSKILLED PERSONNEL. ANY SYSTEM DAMAGE CAUSED BY A WRONG INSTALLATION
AND/OR CONNECTION AUTOMATICALLY VOIDS THE WARRANTY.
CARRYING OUT INSTALLATION AND MAINTENANCE OPERATIONS WITHOUT
DISCONNECTING THE VALVE FROM ITS POWER SUPPLY MAY CAUSE SEVERE INJURY.
Do not operate the valve with no load for long periods of time, as this might damage the
components inside the valve.
ARAG declines any responsibility for direct or indirect damage deriving from the type of
uids used in the system.
The use of such substances is made under the full responsibility of the operator, who
therefore must follow the safety measures indicated by the uid manufacturer on the
package and wear suitable personal safety equipment (gloves, coverall, boots, helmet,
etc.) in compliance with the law provisions.
ARAG may not in any way be held responsible for accidents or damage to persons,
animals or things caused by improper, unprotected, or non-recommended use of the
products utilized.

7
6 MAXIMUM OPERATING PRESSURE
The maximum operating pressure of the valve depends on the type of coupling it is tted with (Tab. 2 - Tab. 3).
E.g.: If the valve has different couplings, for instance two threaded couplings and one camlock, the maximum operating pressure
will be equal to the maximum pressure permitted by the coupling with lower pressure.
Mod. 85372 4A44 Female = 12 bar
Mod. 85372 4D44 Female-Camlock = 10 bar
6.1 Overall dimensions
Refer to Tab. 1 and Fig. III - Fig. IV - Fig. V.
7 INSTALLATION
Installation must be carried out by specialized personnel. ARAG may not be held
responsible for damage to persons, animals or things caused by installation carried out
by unqualied personnel.
• The components, pipes and valves that will be installed in the system must withstand a pressure higher than the
maximum one of the system.
• Any constriction in the system may lead to a faulty over-pressure.
• Make sure that hoses, hose tails and valve anges feature a suitable and compatible diameter.
CAUTION: connect the power supply connector to the valve only after having completed
the hydraulic connections.
OPERATING THE VALVE WITH ONE OR MORE INLETS/OUTLETS OPEN IS VERY
DANGEROUS AND CAN CAUSE ACCIDENTS AND SERIOUS INJURIES TO THE
INSTALLATION OR MAINTENANCE PERSONNEL.
DO NOT INSERT ANY FOREIGN BODIES OR YOUR HANDS INTO THE HOLE OF THE
BALL WHILE THE VALVE IS CONNECTED TO THE ELECTRIC POWER SUPPLY, AS THIS
COULD LEAD TO CRUSHING OR AMPUTATION.
CAUTION: TO AVOID DAMAGING THE SYSTEM, MAKE SURE THAT NONE OF THE PARTS
COMES INTO CONTACT WITH MOVING PARTS OF THE FARMING MACHINE.
7.1 Geared motor rotation
The geared motor of the 853 valves can be turned in 90°-steps to set it in the most suitable position according to the system
the valves are installed in.
Turning the geared motor is a simple but delicate operation, which may impair valve operation or lead to system errors and/or
accidents if performed in the wrong way.
It is therefore very important to perform this operation by thoroughly observing the instructions provided in document D30058,
that is available for download in the website www.aragnet.com/download.
ARAG will not be held responsible for any damage to the system, people, animals or
things caused by modications to the ball valve and/or failure to follow the guidelines
outlined in the mentioned documents.
7.2 Attachment
The ball valve is factory set to be attached using bolts (Fig. I) of the type indicated in section 7.3.
- Insert the bolts into their respective seats and turn them to the stop position to prevent them from coming out.
On valves with 1” ½ or larger coupling, we recommend also using a flat washer of suitable diameter
(Ø 8 ISO 7089).- Insert the bolts into the holes provided (refer to section “7.4 Drilling template”), then tighten the nuts thoroughly.
No other types of coupling are permitted than those described.

8
7.3 Types of bolts
To attach the valve use bolts of the following types:
• M8 ISO 4014/4017
• 5/16” ANSI B18.2
With coupling greater than 1” ½:
• M8 ISO 4014/4017 + M8 ISO 7089 washer
• M8 ISO 4162 / • 5/16” ANSI B18.2
7.4 Drilling template
Refer to Tab. 1 for the position of the drilling points for the attachment bolts.
7.5 Hydraulic connections
Remove the protective caps and connect the inlet/outlet hoses to the valve, using the correct connections for which it is set.
Take special care, where requested, to insert the supplied O-ring correctly (threaded ends). If, for any reason, the pipes leak at
connection points, apply unsintered PTFE tape to improve sealing.
CAUTION: For the maximum operating pressure for the chosen connection, refer to Tab. 2 - Tab. 3.
Once all the couplings of the valve are connected, put the system under pressure ONLY WITH CLEAN WATER rst to make
sure that the connections are not leaking.
7.6 Wiring connections
The valve must be powered by means of the connector xed to the geared motor.
To connect the valve, use suitable cables available on the Arag catalog.
Connect the gearmotor connector to that of the relevant harness; after making sure
it is correctly inserted, press until it is locked - Fig. II
3-wire operation - Fig. VII 2-wire operation - Fig. VIII
• 12 Vdc power supply, always connected
• With opening/closing command supplied with 12
Vdc, the valve turns clockwise.
• Disconnecting the command power supply, the
valve turns counter-clockwise.
• Rotation obtained by inverting the power
supply polarity with a double switch.
7.7 Position indicator
The external position indicator allows viewing the orientation of the ball inside the valve, thus identifying the opening/closing
status (2 ways) or the uid direction (3 ways).
7.8 Position and power supply LED
The LED indicates power supply status, correct power supply polarity and position of the ball inside the valve.

8 USE
Power the valve using a suitable control device (refer to Tab. 1 for the exact absorption values).
CAUTION: Do not run light valve for a long time, the inside gaskets could be damaged
and the valve could block up.
9 MAINTENANCE
The electric ball valves of the 853 series do not require any particular maintenance.
Internal cleaning can be carried out when the system to which the valve is connected is cleaned. If the maintenance man needs
to open the valve to check the seal or for extraordinary cleaning, before tting it back you must replace the seal kit of the orice
that was opened.
CAUTION: Fitting back the valve without replacing the seal kit can reduce the seal on the
internal ball and therefore cause leaks.
- Unscrew the bolts related to the orice to be opened, then remove it and take out the inner gaskets and the O-ring inserted in
the internal seat of the ange that has been removed.
- Re-position all the gaskets in their seats, as shown in Fig. VI (gasket (1) is not present on all models), then close the ange.
- Insert the bolts in the holes, t back the washers and screw in the nuts by hand.
- To ensure correct operation, the nuts (2) must be tightened using a dynamometric spanner calibrated according to that which
is indicated in Tab. 1.
- Reconnect all the hydraulic connections.
- Restore electric power supply.
- Put the system under pressure ONLY WITH CLEAN WATER and check that the connections are not leaking.
