3.4 Operating elements
3.4.1 Valve insert “QA”
Set the flow rate with the help of the presetting
key which is mounted onto the handwheel of
the valve insert "QA" (the set values are visible
from outside). This will protect the setting
against unauthorised tampering. The valve
insert is infinitely adjustable. The setting can be
modified whilst the system is in operation.
