Installation notes
Recommended installation positions
The ball valve can be installed upright to horizontal. The ball valve may not be installed
in a hanging position, i.e. with the stem pointing downwards.
90
0°
Mounting position in the return
Installation in the return is recommended.
Water quality requirements
The water quality requirements specified in VDI 2035 must be adhered to.
Belimo valves are regulating devices. For the valves to function correctly in the long
term, they must be kept free from particle debris (e.g. welding beads during installation
work). The installation of suitable strainer is recommended.
The water must exhibit a conductivity ≥ 20 μS/cm during operation for correct
functioning. It should be noted that, under normal circumstances, even filling water
with a lower conductivity will experience an elevation of its conductivity to above
the minimum required value during filling and that the system can thus be put into
operation.
Elevation of conductivity during filling caused by:
- untreated residual water from pressure test or pre-rinsing
- metal salts (e.g. surface rust) dissolved out of the raw material
Stem heating
In cold water applications and warm humid ambient air can cause condensation in
the actuators. This can lead to corrosion in the gear box of the actuator and causes a
breakdown of it. In such applications, the use of a stem heating is provided.
The stem heating must be enabled only when the system is in operation, because it
does not have temperature control.
Servicing
Ball valves, rotary actuators and sensors are maintenance-free.
Before any service work on the final controlling device is carried out, it is essential to
isolate the rotary actuator from the power supply (by unplugging the electrical cable
if necessary). Any pumps in the part of the piping system concerned must also be
switched off and the appropriate slide valves closed (allow all components to cool
down first if necessary and allways reduce the system pressure to ambient pressure
level).
The system must not be returned to service until the ball valve and the rotary actuator
have been correctly reassembled in accordance with the instructions and the pipeline
has been refilled by professionally trained personnel.
