Pressure / Vacuum Valve Question.

[bevjones2009]

Hi everyone,

I work for a company that repair, test and certify all types of pressure safety valves.

I do a lot of spring and pilot valves, but have recently came across low pressure weighted valves. I was just wondering if there was a calculation to estimate the amount of weight (including the pallet) to enable the valve to lift at a certain pressure.

I was thinking along the lines of a transposition of formula maybe (Pressure = force / area), but I am not quite sure, and with it being a safety device I am unwiling to try something with out some sort of a clue.

I thought someone may have an excel file with the calculation, mabe not.

Any help is greatly appreciated.

I have no spreadsheet, but pressure = pallet weight/area is correct.

I thought a company that repairs, tests and certifies all types of pressure safety valves would have expertise in this area.

Good luck,

We do, I do have some sheets what tell us exactly what weight to use to gain whatever pressure, but I always like to have a little knowledge rather than read from a sheet of paper.
