Litšobotsi tse ntle tsa phallo le ts'ebetso e ntle ea phetoho. Valve ea heke ea tiiso e thata e loketse peterole, lik'hemik'hale, metallurgy, matla a motlakase le liindasteri tse ling. Ha u sebelisa valve ea heke ea tiiso e thata, lintlha tse latelang li lokela ho hlokomeloa: 1. Khetha tlhaloso e nepahetseng le thepa, 'me u khethe ho ea ka litšoaneleho tse mahareng le tikoloho ea tšebeliso ho netefatsa ts'ebetso ea valve. 2. Ts'ebetso e tla etsoa ho latela taelo ea ho kenya valve le ho sebetsa. 3. Boloka valve e hloekile ebile e omme nakong ea ts'ebeliso ho qoba kutu le mengoallo holim'a metsi. 4. Ho boloka le ho sebetsana le valve ho lokela ho ela hloko ho qoba ho thulana le ho sisinyeha ho tebileng. Mabapi le tlhokomelo, valve ea heke e thata ea tiiso e na le nako e telele ea bophelo 'me e batla e le bonolo ho e boloka, empa e hloka tlhahlobo ea kamehla, tlhokomelo le tlhokomelo. 1. Sheba ts'ebetso ea ho tiisa ha sebaka sa li-valve tsa heke. Haeba metsi a lutla, khutlisetsa reng e koalang sebaka kapa likarolo tse ling tsa ho koala ka nako. 2.
