Connections
The pressure loading valves have an input (A) and an output on the pressure side (B).
They are installed in the pressure line.
Pressure loading valves DN4 and DN8 can also be mounted directly on the pressure
valve for the dosing pump with an optional adapter (D) (for the adapter for pump
installation, see section ’spare parts and accessories’).
!
Warning
During installation, observe the flow direction of the dosing line. (Direction arrow
on valve housing)
Caution
When using a pressure loading valve in conjunction with a pulsation damper, the
pressure loading valve must be installed after the pulsation damper.
Note
It is recommended that the pressure loading valve is installed directly in front of
the addition point in the dosing line.
For direct pump installation, the line connected to the injection unit should be as
short as possible.
