8.11.5.4 Mounting of the Actuator on the Manifold
1) Mount actuator to the holding ring (8).
2) Lubricate the thread of the hexagon socket set screws (10) with high-
temperature assembly paste (anti-seize compound).
NOTICE
This is an important measure to prevent thread corrosion due
to aggressive gases, which could be released during plastics
processing.
3) Lock the actuator with hexagon socket set screws (10).
4) Push piston (2) in closed position.
NOTICE
Closed position is when the top edge of the piston has a dis-
tance of 3 mm to the top edge of the actuator housing.
Doc003013.png
5) Mount the valve pin (VP) into the valve pin guide.
6) Place the hanger screw (3) on the valve pin (VP) head.

3) Adjust the valve pin with a hexagon
socket wrench (T6) as followed.
4) Still hold the piston against turning
with the adjustment tool (T5.1).
Doc003016.png
NOTICE
The basic setting for the
valve gate pin is 10 mm
between the piston (2) top
edge and the top edge from
the hanger screw (3).
5) Rotate the hanger screw (3) with a
hexagon socket wrench (T6) into the
piston (2).
NOTICE
The exact position for the valve pin (VP)
has to be checked at the front of the valve
pin - depends on the nozzle tip.
The reason to unscrew the hanger screw
(3) would be for valve pin maintenance or
replacement.
If the deviation to the basic settings
of 10 mm is more than 0,5 mm, the
adjustments do not correspond to
the parameters of the mold or do not
correspond to the Synventive standard.
