Here is a little tip that improves the consistency of a reg that uses Belleville washers as the spring
Belleville washer are stamped out of a flat sheet, as such the edges are often sharp and have little ridges, although tiny they don’t allow the washers to stack on top of each other perfectly.
The solution is simple, with a sheet of 1000gr emery paper on a hard flat surface, lightly rub both sides of the washer to remove any burrs,
The photo show the before and after of both side of the washer.
After de-burring, clean the washers with solvent then apply the smallest smear of lubricant before fitting into the reg. This might seem like a bit of a faff but trust me, it makes the washer stack more evenly, easier to set the pressure and is more consistent
