Kv to Av

Type a value in Kv to get it in Av instantly.

0.00024Av

That's 2.3× as open as a small control valve, while a domestic ball valve is 1.3× higher. At a one-bar drop that passes about 166.7 liters a minute of water.

What it means

How much passes through?

Flow coefficients are for water. Gas, steam and viscous liquids need their own sizing equations, and choked flow caps the answer entirely.

The math

How to convert Kv to Av

To convert Kv to Av, multiply by 2.4×10⁻⁵.

Example: 10 Kv × 2.4×10⁻⁵ = 0.00024 Av.

In the other direction, 1 Av = 41,666.7 Kv.
