Design valve keeriiɗo ngam ittude cavitation huutortoo ko ɓuuɓri feccere e ɓuuɓri ɓuuɓri:
“Diversion valve” ko feccude ɓuuɓol mawngol e ɓuuɓol tokosol keewngol, tawa laawol ɓuuɓol ngol ina fawaa mbele ɓuuɓol ngol ina rewa e limoore udditgol tokosol gonngol e dow mum. Nde tawnoo feccere e mawneeki ɓuuɓol ngol ina hiisee e udditgol ngol ɓuuɓol ngol rewata. Udditgol ɓurngol famɗude ngol ina addana ɓuuɓri tokosiri, ɗum noon ina addana ɓuuɓri ustaade e bonnude so tawii ko bonnugol.
“Graded pressure drop” firti ko valve oo ina waɗi toɓɓe ɗiɗi walla ko ɓuri ɗum e nder njuuteendi, ɗum noon, e nokku ɗo ɓuuɓol ngol fof woni ɗoo e doggol gootol, ina ƴetta doggol tokosol keewngol. Ko famɗi fof ɓuuɓol gootol ina waawi haɗude ɓuuɓol e nder ɓuuɓol ngol ɓuuɓol ɓuuɓngol ndiyam ɗam, ɗum noon ittude feere cavitation e nder valve.
Ko jiidaa e diverting e ɓuuɓri dogdu staging e nder valve gooto ina addana moƴƴinde cavitation reentaade e. E nder waylude valve, jogaade valve control e doolnude e naatirde valve ina ɓura toowde (yeru bannge ɓurɗo woɗɗude dow, walla e tooweeki les), sahaa e sahaa fof ina itta caɗeele kavitaasiyoŋ.
