"Hydrocontrol MTR" (lead-free)
5.3 Initial Operation
WARNING
Danger from overpressure
and leaking medium!
Overpressure in the system
can result in injuries from
parts suddenly coming
loose and media escaping
in an uncontrolled fashion.
Maintain the admissible
operating pressures.
Perform a leakage test.
Before initial operation, the sys-
tem must be fi lled and deaera-
ted.
Setting the fl ow volume
using calculated preset values
Turn the handwheel to a preset
value to regulate the fl ow volume
required for the line.
The preset values depend on the parameters of the sys-
tem in which the valve is installed. If the volume fl ow and
pressure loss are known, you can determine the preset
values by using the fl ow rate diagrams in the appendix to
these instructions.
