Valve pɔtɛɛ he ŋaa ni akɛjieɔ cavitation kɛ mligbalamɔ kɛ nɔnyɛɛ ni baa shi tsuɔ nii:
“Valve diversion” ji ni aja nu agbo ko mli awo nu bibii babaoo amli, ni afee valve lɛ nu gbɛ lɛ bɔni afee ni nu lɛ atsɔ ŋmeii bibii ni kɛ amɛhe kpãa gbee lɛ ayibɔ mli.

Nibii ni akɛfee ekome ni tsɔɔ gbɛ kroko nɔ kɛ nɔnyɛɛ ni baa shi yɛ valve kome mli lɛ haa cavitation shitee-kɛ-woo lɛ yaa hiɛ kɛtsɔ.
