Ivalve yombane yohlobo lwepiston yomoya luhlobo lwesivalo esinokulawula ukuhamba komoya okungazinzanga kumbhobho, ekwaziwa ngokuba yivalve yokuqukuqela yombane, eqhutywa yivalve yombane ye-turboworm drive valve crankshaft drive piston ebuyisela isenzo ukuqonda umgaqo wokuhamba. . Ifanele umoya, ingasetyenziselwa ukusetyenziswa kwemibhobho yamanzi. Isetyenziswe ngokubanzi kwiindawo zokucocwa kwamanzi amdaka, izityalo zamanzi, iiprojekthi zokuguqula kunye nezinye imidiya yomoya, inkqubo yenethiwekhi yombhobho wamanzi, ukulungelelanisa ukuhamba kombhobho ophakathi, ukuhamba kunye nokulungelelanisa uxinzelelo lombhobho wombhobho.
