5.1 Installation, Hydraulic
Testing
The Flow Control always needs a relief
valve upstream of it to be able to test the
Flow Control.
The Flow Control threaded connections
and the connections to the lines need to
be leak-free.
Operating status
Never allow the Flow Control's maximum
permissible operating pressure (10 bar) to
be exceeded in any operating status of the
system.
Only operate the Flow Control vertically.
Using a foot valve
Install a foot valve on the suction side of
the metering pump. Deposits in the Flow
Control can block the float.
Wetted materials:
n
Housing: PVDF
n
Float: PTFE coating
n
Seals: FPM-B or EPDM, depending on the
order number.
When metering aggressive media, take into
consideration the resistance of the materials
used – refer to the ProMinent® Resistance List
in the latest product catalogue or at
www.prominent.com
.
