3.4 FILTERS
The GASCAT called pilot blocks consisting of pilot and booster has always a mechanical barrier against solid
impurities, this barrier is composed by a filter element in polypropylene with filtration degree of 10 microns.
This barrier aims to prevent solid contaminants in the pipe can clog or damage the internal pre regulator and the pilot,
but it is important to note that this filter does not replace the filtration system that should be provided in the
previous steps to pressure regulating so as to leave the clean fluid and correct operating conditions, the filter is
designed to serve as a last barrier to the solid contaminants.
The HORUS pressure regulators are available with F-10 filter, mounted separate from the pilot block or compact
version with the filter element already attached to the pre regulator.
4.0 – INSTALLATION
4.1 FILTER
We recommend installing a filter type "cartridge", with grade 5 Micra filtration, as close to the regulator inlet, without
being united flange to flange, therefore, the filter installed immediately upstream of the regulator may cause turbulence
causing disturbance in the regulator pressure control. Care for the filter installation is essential to the smooth operation of
the instrument as any existing particles in the pipe can become lodged between the seat and the shutter, damaging them
and causing feedthrough.
4.2 CLEANING
Check the pipe cleaning before valve installation. We recommend a complete purge of the line with nitrogen or
compressed air.
4.3 DIRECTION OF FLOW AND SYSTEM INTEGRITY
Before proceeding with the installation of the equipment you must ensure that:
1) The equipment is in perfect condition or has function in damaged evidence in the handling during transport, if
you have a fault not proceed with the installation and contact the GASCAT.
2) The area in which access and installation of the equipment is suitable, including for future maintenance.
3) The facility was designed to support the load imposed by equipment.
4) The input and output connections where the pressure regulator is installed are perfectly aligned.
5) All outlets of necessary pressure in the pipeline downstream equipment for sensing, were provided and are
respecting the dimensions recommended by the manufacturer.
6) It was predicted gauge or any other equipment upstream pressure indicator and downstream equipment to
allow the correct fit for the start-up.
7) was provided a line of vent between the regulator and the first output block valve to assist the operator during
start-up.
8) Check the direction of flow of the body marked throttle valve and pay attention to the time of installation so that
it is properly positioned.
