4.6.2 COMMISSIONING (SINGLE REGULATOR SPAN)
Using, as a reference, the assembly scheme presented in item 4.5.1, proceed to the description on
commissioning of the regulator model URANO for a simple regulation span, considering that the
recommendations made in section 4.6.1 of this manual have been properly observed.
The referred to procedure considers the use of valves model GIPS-FC GASCAT as safety device.
1) Shut-off the vent valve.
As the line shut-off valves are closed, we will use the vent valve to simulate a small flow and so
proceed with the regulator adjustment before aligning the span.
2) Check if the pilot regulation spring is properly relieved (discharged).
Relieving the regulation spring we ensure that the valve will remain in the closed position when
pressurized.
3) Check if the discharge valve (needle valve) is open by 1/8 of a turn.
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 URANO 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 URANO,
remember that you must perform the set point adjustment before
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.
