Izingxenye ze-valve kufanele zihlangabezane nezinqubo ezilandelayo zokuhlanza ngaphambi kokuhlanganisa:
1. Ngokuya ngezidingo zokucubungula, ezinye izingxenye zingadinga ukupholisha. Ama-surface burrs nezinye izibi zingasuswa.
2. Zonke izingxenye kufanele zehliswe amafutha.
3. Ngemva kokwehlisa amafutha, yenza ukucofa kanye nokwelapha usebenzisa i-phosphorus{1}}i-ejenti yokuhlanza yamahhala.
4. Ngemva kokukhetha nokuhlanzwa, hlambulula kahle ngamanzi ahlanzekile ukuze uqiniseke ukuthi akukho zinsalela zamakhemikhali. Lesi sinyathelo asifakwa ezingxenyeni zensimbi ye-carbon.
5. Sula ingxenye ngayinye yome -ngendwangu engalukiwe ukuze uqiniseke ukuthi akukho lint elihlala ngaphezulu, noma wome nge-nitrogen ehlanzekile.
6. Sula ingxenye ngayinye -ngendwangu engalukiwe noma ngephepha lokuhlunga elicolisekile elicwiliswe ekuhlaziyeni{2}}utshwala bezinga kuze kungabi bikho amabala.
