4.1. Preparation for installation
Before installation, make sure the following conditions are met:
• The installation area has easy access and the device is to be installed in a position
where operation and maintenance work can be performed safely.
• The product will be installed with proper support and free of any stresses that can
be induced by the system due to e.g. thermal pipe expansions / contractions during
CIP/SIP. The necessary precautions are recommended during system design.
• The pipeline where the product will be installed is designed in such a way that it
takes into account the weight of the product. The pipeline may require support on
both sides next to the product, particularly if its size and weight are considerable
and especially if vibrations are to be expected in the system.
•
Consider good hydraulic flow control to avoid pressure surges and avoid dead legs
on pipeline branches.
• The product is not damaged.
• Make sure all the necessary materials and tools are readily available during
installation work.
• Referring to this Installation and Maintenance Instructions (IMI), Information Sheet
(IS) and nameplate, check that the product is suitable for the intended installation:
temperature, medium, pressure, temperature, etc. – see section 1.2 – Intended
use.
•
Check that there are no foreign bodies inside the pipelines and ancillaries, flushing
may be necessary. These should be thoroughly cleaned.
•
A filter may be necessary to install upstream of the regulator in some applications,
protecting it from solid particles.
• A safety valve must be installed downstream if the inlet pressure to the regulator
can exceed its maximum downstream pressure rating or the pressure rating of any
equipment installed downstream.
•
A shut-off valve is installed upstream and downstream of the regulator to facilitate
start-up, maintenance and troubleshooting. A bypass line is recommended as it
additionally prevent system shutdown during maintenance procedures, in which
case a manual valve should be fitted to allow regulation of downstream pressure.
• The pressure regulator will not be thermally insulated.
• A pressure gauge is installed both upstream and downstream of the regulator for
monitorization, set point adjustment and troubleshooting.
If the regulator is fitted with an integrated downstream pressure gauge, the
displayed pressure may be slightly higher compared to a separate gauge
installed further downstream.
