4.3 – FILTER
We recommended the installation of a basket type filter, with minimum 150 mesh, as close as possible to the regulator
input, without being joined flange to flange, because, if the filter is installed immediately upstream of the regulator, it can
produce turbulence that will cause disturbances in the pressure control of the regulator. Care with the filter installation is
essential to the perfect operation of the apparatus, because, particles eventually found in the piping can lodge themselves
the seat and the shutter, damaging them and producing direct flow.
4.4 – CLEANING
Check piping cleaning before the installation of the regulator. We recommended a complete purge of the line with
nitrogen or compressed air.
4.5 – FLOW DIRECTION
It is necessary to verify the flow direction before installing the regulator; this information could be found into marks in the
equipment body.
The pressure regulator model DOMUS HF is designed to work in the horizontal position with the actuator in the top
position.
