6.1 Commissioning
Connect the hydraulic hoses to connections “A” and “B”. Refer to 4.1 to ensure turning direction of
actuator in relation to connections.
NOTE:
Refer to manufacturer manual of
the control unit to ensure proper
commissioning and operation with
control unit in use.
WARNING:
Before first operation the hydraulic
system has to be cleaned and bled
carefully so that there is no air in
the hydraulic system.
NOTE:
Written permission from Vexve Oy
is required to perform hydraulic
adjustment.
WARNING:
It is strictly prohibited to exceed
the torques in the tables 1 and 2!
Too high torques can damage the
valve or the actuator!
6. Commissioning and hydraulic adjustment
See Figure 6
The maximum hydraulic operating pressure can
be adjusted (and limited) by the control block
(if equipped) of the actuator for both directions
separately: By turning the adjustment screw
(1) clockwise the maximum hydraulic operating
pressure increases and vice versa it decreases
by turning the screw counterclockwise.
If needed, increase the maximum operating
pressure, maximum allowed operating pressure
is 200 bars.
A pressure gauge can be attached to the control
block to monitor the hydraulic pressure while
adjusting. The pressure gauge can be mounted
on connections (2) “MPA” for connection “A” and
“MPB” for connection “B”.
