Sigma_i: Incipient Cavitation.

In ratral/wcontrolvalve: Meta Analysis Plunger Valves

Description

The onset of cavitation, where only small vapor bubbles are formed in the flow stream. A cavitation level sufficient to begin minor, observable indications of pitting damage. - Onset of cavitation; - Detect using high-frequency vibration measurement; - Very local phenomenon; Transient: random “ticks” sound; - Low-level cavitation: usually not damaging; - Occurs prior to the loss of capacity

Arguments

x	valve position
b	steepness
d	upper value
e	the effective dose
fls	liquid pressure recovery full open (max between fl and Flp/Fp)
