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.
Installation position in return
Installation in the return is recommended.
Water quality requirements
The water quality requirements specified in VDI 2035 must be adhered to.
Ball valves are regulating devices. The use of dirt filters is recommended in order to prolong
their service life for performing control tasks.
Maintenance
Ball valves, rotary actuators and sensors are maintenance-free.
Before any kind of service work is carried out on the actuator, it is essential to isolate the
rotary actuator from the power supply (by disconnecting the electrical cable). Any pumps
in the part of the piping system concerned must also be switched off and the appropriate
slide valves closed (allow everything to cool down first if necessary and 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 properly reassembled in accordance with the instructions and the pipelines have been
refilled in the proper manner.
Flow direction
The direction of flow, specified by an arrow on the housing, is to be complied with, since
otherwise the flow rate will be measured incorrectly.
Earthing
Above DN65, it is imperative that the measuring pipe be correctly earthed in order to ensure that
the volumetric flow sensor does not make any unnecessary incorrect measurements.
