5) Check if all connectors are properly secured in the station before starting pressurization of the span.
6) Check if the installed equipment has suitable operating conditions, using the information available on the
nameplate attached to the equipment.
7) Make sure that the SSV is in the shut position.
ATTENTION:
* Under no circumstances proceed with pressurization of the span where
the equipment is installed by the downstream valve of the equipment.
* Under no circumstances proceed with the depressurization of the span
where the equipment is installed by the valve located upstream of the
equipment, such as the filter drain.
ATTENTION:
GASCAT’s SSV are sent to the field already calibrated, however,
depending on transport conditions and the equipment handling the valve
may have its set point changed.
Therefore, we recommend that you check the SSV set point with the
help of an external air supply directly connected to the actuator, before
proceeding with the pressurization of the span.
Model ARES N valves are not sent to the field with adjusted set points;
this measure tends to preserve the life of the equipment internals.
Therefore, after receiving a pressure regulator valve model ARES N
remember that you must perform the set point adjustment before putting
the equipment into operation.
The pressure reducing station setting shall be in accordance with the DIN EN 12186 / NBR 12712
standards and all other regulations in force in the region where it will operate.
