1. General
Vexve Oy’s Hydrox control units are the best
solutions for controlling the Hydrox actuators.
Control units are specifically designed to
operate seamlessly with Hydrox actuators
and therefore with Vexve and Naval ball and
butterfly valves. The Hydrox control unit is the
perfect solution for easy and reliable operation
with minimum need of maintenance and with
maximum safety at all times.
NOTE:
When intending to use the control unit with actuators from other manufacturers than
Vexve Oy please contact Vexve Oy to ensure its suitability.
For detailed technical information including dimensions and weights, pressures etc. please refer to
Hydrox Product catalogue or data sheets (www.vexve.com).

3. Unloading and storage
Check that the content of the delivery is as
ordered. Check that the control unit and related
equipment have not been damaged during
transportation.
Store the control unit carefully before
installation, preferably in a well-ventilated, dry
place, on a shelf or a wooden grid to protect it
from rising damp.
Protect the cabinet’s ingoing components
from sand, dust, water, moist and other
contamination.
Protect bare metal surfaces with anti-corrosive
agent before storage.
The control unit must be transported to the
installation site in a sturdy package. Do not
remove any protectors before installation.
Protect the control unit from dust and other
impurities.
Take the weight of the control unit and its
equipment into account when handling them.
The maximum storage time is two years.
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 control unit are made
of recyclable materials. The material type is
marked on most parts. Separate recycling and
disposal instructions are available from the
manufacturer. The control unit can also be
returned to the manufacturer for recycling and
disposal against a fee.

4. Control unit installation
Figure 2. Mounting holes.
See figure 2.
Control units must always be installed securely to the plinth with four screws from the corners (1). The
plinth must be installed to the ground according to the instructions on the plinth. Cabinets must be
mounted and used in the position according to the drawing below.
Preparations before comissioning:
·Make sure the hydraulic connections are clean.
·Keep all protective caps on the hydraulic connections until hoses are connected. This is for
preventing the system and its components against contamination.
·Check that all bolts and hydraulic couplings are fastened. The control cabinets are always pressure
tested and verified before delivery. However, during delivery, the threaded connections can loosen
and therefore this should be controlled before pressurizing the system.

Hydrox control units need only little maintenance.
The correct choice of control unit, valve and actuator combination as well as careful installation,
commissioning and use significantly reduce any need for maintenance.
We recommend checking the following periodically to ensure long-term operational reliability, even
when seldom used (around ten times a year or less):
Approximately six months after commissioning and then once a year, check the functionality of the
control unit, inspect the control unit for oil leaks (carefully tighten if any leakages occurred) and ensure
the tightness of the hydraulic hoses between the control unit and actuator. Test also the functionality
of the position indication box.
5. Maintenance
5.1 Oil change
Oil changes are necessary and depend on the size of the system. Under clean conditions, it is
recommended that the condition of the oil is inspected approximately every two years and that the
oil is replaced at every second inspection. If dirty/low-quality oil is used, oil changes are necessary at
shorter intervals. Because the small oil volume in part-turn actuators compared to the volume in the
pipework, there is no oil change during the operating cycles. Because of this, it is recommended to
change the hydraulic oil so that the oil changes also inside the part-turn actuator and hoses not only in
the hydraulic pump.

5.2 Battery replacement
See figure 3.
Battery must be tested by pressing the test button on the indication box during the maintenance
periods.
Following steps are needed to replace the battery:
1. Loosen the corner screws (1) of the position indication box and pull the front plate gently. Note
that the wires inside the box should not be loosened.
2. Replace the battery (2) with a similar one.
3. Close the indication box by mounting the front plate and tightening the corner screws.
