TORQUE ADJUSTMENT THROUGH BY-PASS VALVES
(operating pressure for anti-crush safety)
At the first installation the external manual release is not yet mounted (Fig. 24), so after the by-pass valves
adjustments (Fig. 25) by using the provided special key «
A
», it can be mounted as shown on page 13.
All the successive adjustments of the valves (eg. periodic maintenance) should be made by unscrewing
completely the external manual release (see page 13) then make adjustments as shown in Fig. 25
The opening and closing forces transmitted to the gate by the motor-pump assembly are regulated by
adjusting two by-pass valves; the grey valve adjusts the opening pressure while the yellow valve adjusts the
closing pressure. To increase the operating pressure turn valves clockwise; to decrease turn anti-clockwise
THE MAXIMUM THRUST FORCE DURING THE MOVEMENT, MEASURED AT THE LEADING EDGE OF THE
LEAF, IS SUBJECTED TO THE LAWS IN FORCE IN THE COUNTRY WHERE THE GATE IS INSTALLED
