The calculation formulas are purely practical formulas and must only be used with the specified units. Please pay close attention to the specified units.

Δ p = p1 - p2

pü = p - pl

pü = Overpressure

p = absolute pressure of the medium

pl =Atmospheric pressure outside the valve

If the exact value of the atmospheric pressure (pl) is unknown, use ~ 1000 hPa (1 bar) as a default value.
