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 AND ASSEMBLY OPTIONS
Before starting the equipment installation, it is necessary to check if:
9) The equipment is in perfect conditions, or it has evidence of damage during transportation. If so, do not proceed
with the installation and contact GASCAT.
10) The space provided for access and installation of the equipment is adequate for future maintenance.
11) The installation is designed to support the load applied by the equipment.
12) The inlet and outlet connections, where the pressure regulator shall be installed, are perfectly aligned.
13) All necessary pressure-sensing pick-ups, downstream of the equipment pipeline, were provided respecting the
dimensions recommended by the manufacturer.
14) A pressure gauge, or any other pressure-measuring device, was foreseen for the upstream and downstream of the
equipment to allow for the correct setting up at the operation start-up.
15) A vent line was planned between the regulator and the first outlet shut-off valve to assist the operator during start-up.
16) Check the flow direction marked on the body of the pressure-regulating valve and pay attention at the time of its
installation so that it is properly positioned.
