1. Mehato ea ho hloekisa bakeng sa ho tlosa li-valve:
Likarolo tse tlositsoeng tsa valve li tlameha ho phekoloa ka mokhoa o latelang pele ho kopano:
(1) Ho ea ka litlhoko tsa ts'ebetso, likarolo tse ling tsa li-valve li hloka ho belisoa ntle le machining burrs holim'a metsi;
(2) Hlakola likarolo tsohle tsa valve;
(3) Pickling le passivation li tla etsoa ka mor'a ho senya (setsi sa ho hloekisa ha se na phosphorus);
(4) Ka mor'a pickling le passivation, hlatsoa ka metsi a hloekisitsoeng ntle le masala a reagent (mohato ona o siiloe bakeng sa likarolo tsa carbon steel);
(5) Karolo e 'ngoe le e' ngoe ea belofo e tla hlakoloa e omme ka lesela le sa lohiloeng, 'me bokaholimo ba likarolo tse kang boea ba terata bo ke ke ba bolokoa, kapa bo omisitsoe ka nitrogen e hloekileng;
(6) Hlakola karolo e 'ngoe le e 'ngoe ea li-valve ka lesela le sa lohiloeng kapa pampiri e nepahetseng e silafalitsoeng ka joala bo hloekileng ho fihlela ho se na 'mala o litšila.
2. Litlhoko tsa kopano bakeng sa li-valve tsa degreasing
Likarolo tse hloekisitsoeng tsa valve ea degreasing li tlameha ho koaloa le ho bolokoa bakeng sa ho kenngoa. Litlhoko tsa mokhoa oa ho instola ke tse latelang:

(2) Basebeletsi ba kopano ba tlameha ho apara liofarolo tse hloekileng tsa k'hothone, likatiba tsa k'hothone tse hloekileng, ho se na moriri o lutlang, lieta tse hloekileng le liatlana tsa polasetiki (ho tlosa mafura).
(3) Lisebelisoa tsa kopano li tlameha ho tlosoa le ho hloekisoa pele ho kopano ea li-valve tsa degreasing ho netefatsa bohloeki.
