Self operationd regulating valve ke valve e sebelisoang ho laola khatello ea metsi, sekhahla sa phallo le mocheso. E ka fetola ka bo eona khatello ea phallo e ipapisitseng le liphetoho tsa khatello ea inlet ho boloka boleng bo sa feleng ba khatello. Mofuta ona oa valve o sebelisoa haholo masimong a indasteri, joalo ka lik'hemik'hale, peterole, matla, joalo-joalo.
Khatello e sa khaotseng ea othomathike, khatello ea morao e tsitsitseng, sekhahla sa phallo, le valve e fokotsang khatello ea mouoane bakeng sa liphaephe tsa naetrojene ke mofuta o ikhethileng oa li-valve tse laolang tse sebelisoang haholo lits'ebetsong tsa lipeipi tsa naetrojene. E ka khona ho fetola sekhahla sa khatello le phallo ea nitrogen ho boloka boleng bo tsitsitseng ba khatello ea mokokotlo. Mofuta ona oa valve hangata o na le likarolo tse kang 'mele oa valve, sekoahelo sa valve, setulo sa valve, valve disc, selemo, joalo-joalo.
