MAXIMUM OPERATING PRESSURE
The maximum operating pressure of the valve depends on the type of coupling it is fitted with
(
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. 853D2 4A44 Female
= 12 bar
Mod. 853D2 4D44 Female-Camlock
= 10 bar

INSTALLATION
Installation must be carried out by specialized personnel. ARAG may not be held
responsible for any damage to persons, animals, or objects caused by installation
carried out by unqualified 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 flanges feature a suitable and compatible diameter.
WARNING: do not connect the electric connectors to the valves. This operation must
be performed at a later stage and only by following the instructions provided in the
SYNCRO computer manual.
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.
WARNING: TO AVOID DAMAGING THE SYSTEM, MAKE SURE THAT NONE OF THE
PARTS COMES INTO CONTACT WITH MOVING PARTS OF THE FARMING MACHINE.

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 can be required to [email protected]
ARAG will not be held responsible for any damage to the system, people, animals
or objects caused by modifications to the ball valve and/or failure to follow the
guidelines outlined in the mentioned documents.
