4.1 Maximum operating pressure
The maximum operating pressure of the valve depends on the type of coupling it is fitted with (refer
to Tab. 1).
E.g. If the valve has two threaded couplings and one camlock, the maximum operating pressure
is equal to the maximum pressure permitted by the coupling.
Mod. 453725A66 Female = 10 bar
Mod. 453725D66 Female-Camlock = 8 bar

5 INSTAllATION
Installation must be carried out by specialised personnel. ARAG may not be held
responsible for damage to persons, animals, or devices caused by installation
carried out by unqualified personnel.
CAUTION: Connect the power supply connector to the valve only after completing
correctly the hydraulic connections.
OPERATING THE VALVE WITH ONE OR MORE INLETS/OUTLETS OPEN IS VERY DAN-
GEROUS AND CAN CAUSE ACCIDENTS AND SERIOUS INJURIES TO THE INSTALLA-
TION 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.
5.1 Attachment
The ball valve is factory set to be attached using bolts (Fig. 1) of the type indicated in section 5.2.
A = 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).
B = Insert the bolts into the holes provided (refer to section 5.3 - Drilling templates), then tighten
the nuts thoroughly.
No other types of coupling are permitted than those described.
