Siklama futhi sakha i-valve yekhemikhali ejikelezayo ngokwezimpawu zezinto ezivutha umlilo, eziqhumayo, ezinobuthi kanye nezibolayo ezikhishwa isitshalo samakhemikhali.Ekukhiqizeni amakhemikhali, okuphakathi kuvame ukuba nomfutho ophezulu kanye nezinga lokushisa.Ngokwezici zezinto ezihlukahlukene, i-carbon steel, i-alloy steel, insimbi ekhonjiwe, insimbi engagqwali nezinye izinto zensimbi ezihlukahlukene zingakhethwa njengezinto zokusetshenziswa ze-valve ejikelezayo ukuhlangabezana nezidingo zefektri yemikhiqizo yamakhemikhali.
