Make sure that the distances A and B are A 130 mm and B 130 mm, the centre of the gate hinge and the centre of the rear bracket of
the operator to be referred to respectively. Distance D is never to be varied and must be equal to 80 mm from the centre of the ball
bearing joint to the gate surface. Picture 8.
Open the valve enclosure by using the supplied key and
release the operator by means of the special key No.
1625 which comes inside the enclosure, already fitted on
the release valve. The shaft will now be allowed to move
freely in and out by pushing the gates by hand in a very
smooth way. One complete cycle (open and close) is
recommended so that the piston reaches the limit of the
permitted stroke. Picture 7.
Fit the gates with an electric lock in case it is installed the non locking operator. With the two-way locking operator it is recommended
that the gates are not wider than two meters each. Should they be more than two meters an electric lock is to be installed to help the
gates to be firmly held in the close position. Picture 10.
With single gates the electric lock is to be installed horizontally at a suitable height from ground level. With double gates it is to be fitted
vertically at the foot of the gates. Picture 11.
Should a
mechanical latch
be required for better hold of the gates in the close position on to the gate stop, the electric
lock is to be fitted horizontally 70 cm from ground level. The gate with the electric lock must open 5 degrees more than
the other one.

PLEASE NOTE:
THE VALVE THAT CONTROLS THE OPEN THRUST POWER
MUST BE SUNK 2 TURNS DEEPER THAN THE CLOSE VALVE
TO PREVENT THE FAILURE OF THE OPERATOR IN THE OPEN
CYCLES WHEN HIGHER PRESSURE IS REQUIRED.
The gate carrying the electric lock must be allowed to open 5 degrees
more than the other one to prevent that on approaching the close
position the two gates jam into each other. Important: gate stops are
to be provided at open gate positions to prevent the pistons from
reaching the limit of the permitted stroke. Picture 10.
