Ivalve yovemvane enomugqa we-PTFE isebenzisa ipuleti levemvane elinemigqa ye-PTFE elinendawo evalekayo eyindilinga.I-valve iyasebenza kalula, inomsebenzi wokuvala okuqinile, nempilo ende yesevisi;ingasetshenziselwa ukusika ngokushesha noma ukulungisa ukugeleza.Ifanele izikhathi ezidinga ukubekwa uphawu okuthembekile kanye nezici ezinhle zokulungisa.Umzimba we-valve wamukela uhlobo oluhlukanisiwe, futhi ukuvala kuzo zombili iziphetho ze-valve shaft kulawulwa indawo eyisisekelo ejikelezayo phakathi kwepuleti lovemvane nesihlalo se-valve kanye nerabha ye-fluorine;ukuze kuqinisekiswe ukuthi i-valve shaft ayixhumani nendawo ewuketshezi ekamelweni.Kusebenza kakhulu ekuthuthweni koketshezi namagesi (okuhlanganisa umusi) ezinhlotsheni ezihlukahlukene zamapayipi ezimboni, kanye nokusetshenziswa kwemithombo yezindaba egqwala kakhulu, njengalokhu: i-sulfuric acid, i-hydrofluoric acid, i-phosphoric acid, i-chlorine, i-alkali eqinile neminye imithombo yezindaba egqwala kakhulu .
