Kv Value Calculator - Liquids

This flow calculator is designed for calculating the required Kv flow requirements for use with liquids. Simply enter the details of your application and this results in the calculator giving you the required value in m³/h ready to select your IMI Buschjost valve.

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.
