What to do if resetting PIETRO FIORENTINI SBC 782 is not possible?
If the resetting of your PIETRO FIORENTINI Control Unit is not possible, it could be due to the persistence of the cause which led to downstream pressure increase or decrease. Try to decrease or increase the downstream pressure. Alternatively, the lever system might be broken or chipped, requiring you to change the standard box containing the assembly outside the regulator.
Why does my PIETRO FIORENTINI SBC 782 Control Unit have wrong release pressure?
If your PIETRO FIORENTINI Control Unit has wrong release pressure, it might be caused by an incorrect setting of the maximum and/or minimum spring. Reset it using the rings [14] and/or [15]. Another cause may be friction in the lever system, in that case change the box containing the whole assembly.
What to do if there is leakage from slam-shut obturator in PIETRO FIORENTINI SBC 782 Control Unit?
If there's leakage from the slam-shut obturator in your PIETRO FIORENTINI Control Unit, it could be due to a deteriorated obturator gasket [40]. In this case, change the gasket. Alternatively, the O-ring [15] might be worn and needs replacement, or the obturator seat [104] could be eroded or chipped, requiring a seat change.
How to fix slam-shut obturator that does not close in PIETRO FIORENTINI SBC 782 Control Unit?
The slam-shut obturator in your PIETRO FIORENTINI Control Unit might not close because the control diaphragm [4] has ruptured. To fix this, change the diaphragm.
