3. Unloading and storage
Check that the content of the delivery is as
ordered. Check that the actuator and related
equipment have not been damaged during
transportation.
Store the actuator carefully before installation,
preferably in a well-ventilated, dry place, on a
shelf or a wooden grid to protect it from rising
damp.
Protect bare metal surfaces, shaft parts, and
flange surfaces with anti-corrosive agent before
storage.
The actuator must be transported to the
installation site in a sturdy package. Do not
remove any protectors before installation.
Protect the actuator from dust and other
impurities.
NOTE:
If the actuator is delivered pre-
assembled with a valve refer to the
handling and lifting instructions of
the valve.
WARNING:
It is forbidden to lift the actuator
by the control block! Make sure
that lifting ropes or chains do
not even touch the control block
during lifting.
Take the weight of the actuator and valve into
account when handling them.
When delivered, the actuator is in the open
position. During storage, the actuator must also
be in the open position.
Maximum recommended storage time is two
years. If the actuator is stored for more than two
years, it should be operated and cleaned yearly.
Packaging:
Vexve’s products are protected during
transportation with special packaging. The
packaging consists of environmentally friendly
materials that are easy to sort and recycle.
Recycling the packaging materials at designated
waste collection points is recommended.
The following packaging materials are used:
wood, cardboard, paper, and polyethylene
sheets.
Recycling and disposal
Nearly all parts of the actuator are made of
recyclable materials. The material type is marked
on most parts. Separate recycling and disposal
instructions are available from the manufacturer.
The actuator can also be returned to the
manufacturer for recycling and disposal against
a fee.

4. Functional description
The oil pressure which is supplied through connections “A” and “B” causes a rotary movement on the
actuator shaft. The linear movement of the piston is converted into a rotary movement by means of
multiple gears
See Figure 2
The rotation direction of the actuator shaft depends on which connection the pressure is applied:
· If the pressure is applied to the connection “A” the actuator shaft rotates clockwise closing the valve.
· If the pressure is applied to the connection “B” the actuator shaft rotates counterclockwise opening the
valve.
There is an indicator slot on the top of the actuator shaft so it is easy to notice which direction the shaft
is rotating. When the slot is parallel to the front face of control block, valve is closed. When the slot is
perpendicular to the front face of the control block, valve is open, see Figure 3.

Pressure on A: valve closes.
Pressure on B: valve opens

NOTE:
Avoid removing the actuator from the valve. The actuator has been calibrated at the
factory to ensure that the valve is tight. If the actuator is removed, it may have to be re-
calibrated.
Vexve Oy accepts responsibility only for actuators installed by Vexve.
Refer to the Hydrox product catalogue or data sheets (www.vexve.com) for maximum
permissible diameter of shaft and shaft intrusion. Actuator is equipped with only one key
way so it is not possible to change its installation position on the valve
WARNING:
All couplings and hoses of the actuator, and equipment connected to it, must always be
kept clean since impurities might cause failures in the operation of the system.
If the actuator is equipped with quick couplings and fast and significant changes in
temperature are possible, thermal expansion of the hydraulic oil must be taken into
consideration.
The actuator may not be removed or dismantled if the valve is pressurized! It is
recommended to use the special actuator removal tools!
Incorrect disconnection may cause serious personal injuries as well as malfunction and
damage to the equipment. Extreme caution must be exercised during the disconnection!
Do not use too high torques to operate the valve. Too high torques can damage the valve
or the actuator! See tables 1 and 2 in chapter 6.2.1 for maximum torques.
