MAXIMUM OPERATING PRESSURE
The maximum operating pressure of the valve depends on the type of coupling it is fitted 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

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 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.
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.

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 modifications to the ball valve and/or failure to follow the guidelines
outlined in the mentioned documents.
