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

Δ p = p1 - p2 Overpressure: pü = p - pl		p = absolute pressure of the medium pü = Overpressure 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.
