Flow conditions known as cavitation and flashing originate from vaporization occurring in the throt-tling area. Cavitation occurs when the differential pressure ratio, (according to IEC 60534-8-41,2), is higher than the valve’s coefficient of incipient cavitation, xFz.

Xfz is a coefficient of incipient cavitation. Figure 1 shows the relationship between Xfz, the coefficient of incipient cavitation, and the resultant sound level. Manufacturers publish specific Xfz values for their valves. Xy signifies the maximum cavitation amplitude. It is …

If possible, one should limit the valve's pressure drop below the pressure level indicated by the cavitation index Xfz, where Xfz is the allowable delta P divided by inlet pressure minus vapor pressure (pressures in absolute terms).

First, consult your valve's catalog information to find the Xfz (incipient cavitation) factor for the chosen valve and valve travel. If unknown, check the table below for an approximate value. Take your pressure ratio factor X (see above) and multiply it by 10. Now go to the bottom of graph C.

The document discusses the valve modifier xFz, which describes the onset of cavitation in a valve as a function of workload. xFz values can be obtained from manufacturers as measurement curves or tables relating xFz to workload, allowing for precise sound pressure calculations.

The BAF is a ground test facility to investigate and evaluate anomalies associated with Electronic Warfare systems, avionics, tactical missiles and their host platforms.

Definition of BAF in Military and Government. What does BAF stand for?

The abbreviation BAF stands for Bunker Adjustment Factor, which is a charge applied by shipping companies to account for fluctuations in fuel prices in maritime transport. This adjustment ensures that carriers can maintain profitability amidst volatile fuel costs.
