Ivalvu yethayi iyinto encane kakhulu kodwa ebaluleke kakhulu ethayini lemoto. Ikhwalithi yevalvu ingathinta ukuphepha kokushayela. Uma ithayi livuza, lizokwandisa ukusetshenziswa kukaphethiloli futhi likhulise nengozi yokuqhuma kwethayi, ngaleyo ndlela kuthinte ukuphepha kwabagibeli emotweni.

Ngakho-ke ungayivimbela kanjani ivalvu ukuthi ingavuzi? Kubaluleke kakhulu ukunaka ikhwalithi yomkhiqizo lapho uthenga ivalvu. Kuyadingeka ukuqinisekisa ukuthi ivalvu inomoya oqinile ukuqinisekisa ukuthi akukho ukuvuza komoya okwenzekayo lapho imoto isebenza ngendlela evamile.

Sincoma ukuthi abasebenzisi bazame ukukhetha uhlobo noma umhlinzeki oqinisekisiwe ngekhwalithi lapho bethenga i-valve. Nakuba i-valve ibukeka ifana, abanye abakhiqizi bama-valve abanikeza amanani aphansi bangase bangakwazi ukuqinisekisa ukulawulwa kwekhwalithi. Ukuze banikeze ukuhlolwa kwefektri komoya we-valve ongu-100%.

Ngaphezu kwalokho, kuyadingeka ukuqinisekisa ukufakwa okufanele lapho ufaka ivalvu: ukuvuza kwevalvu esetshenziswayo kuhlobene ngqo nokufakwa okungalungile. Uma kunezinhlayiya eziningi noma ukungcola phakathi kwevalvu nengaphakathi levalvu, noma ngabe ukuvalwa kuhle, kusazoholela ekuvalekeni okubi ngesikhathi sokusebenzisa. Ngakho-ke, kunconywa ukuhlanza ithayi kanye nehabhu ngaphambi kokufaka ivalvu.

Okokugcina, ngisho nevalvu yekhwalithi ephezulu, ngoba yenziwe kakhulu ngerabha, akunakugwenywa ukuthi irabha izokonakala ngemva kwesikhathi eside isetshenziswa. Ivalvu egugayo ingabangela nokuthi ithayi lithambe. Ngakho-ke, kunconywa ukuthi umsebenzisi ayishintshe njalo ivalvu ngemva kokusebenzisa imoto isikhathi eside.
