Mwachidule
Ili ndi mawonekedwe abwino otenthetsera komanso kuzizira, ndipo ma valavu amtunduwu amagwirizana ndi chitoliro, ndipo amatha kuchepetsa kutentha kwa sing'anga mu payipi. Pofuna kunyamula ma viscosity sing'anga omwe adzakhazikika kutentha. Malinga ndi kapangidwe kake ka valavu, imagwiritsidwa ntchito kwambiri pakupanga kwamatauni, mafakitale, zitsulo, mafuta, mankhwala, chakudya, chakumwa, kuteteza zachilengedwe ndi mafakitale ena.

Miyezo
1. Mkulu ntchito chosinthika kudula-kuchokera mtundu. Itha kugwiritsidwa ntchito ngati valavu yokhazikika komanso yotseka valavu.
2. Njira ziwiri zosindikizira, zosiyana ndi kusindikiza njira imodzi, zitha kusindikizidwa moyenera ngakhale kutuluka kwapakatikati kapena "nyundo ya mpweya" kumachitika.
3. Thupi la valve limagwiritsa ntchito ukadaulo wophatikizika wophatikizika, voliyumu yaying'ono ndi kulemera kopepuka;
4. Kapangidwe kowonekera kawiri kalandiridwa. Mukatseka, mbale ya valavu imakulitsa panja kuti ikwaniritse bwino zotsekera dziko; potsegula, mbale ya valavu ndi mphete yosindikiza zimasiyanitsidwa mwachangu kuti zisawonongeke za mphete yosindikiza. Mwanjira imeneyi, makokedwe ogwiritsira ntchito amachepetsedwa ndipo moyo wogwira ntchito wa valve ukuwonjezeka.
5. Mphete yosindikizira ndiyatsopano pamapangidwe ake ndipo imagwiritsa ntchito ukadaulo wapamwamba mdziko lapansi: Chisindikizo cha PTFE chimatengera "milomo ya dzino" kupanga mawonekedwe osindikiza; chidindo cholimba chimatengera "U" mawonekedwe osindikizira. Utumiki wamoyo wosindikiza ndiwotalika komanso wodalirika. Pazikhalidwe za chisindikizo chofewa ndi chidindo cholimba, zimadalira zofunikira za wogwiritsa ntchito, momwe amagwirira ntchito komanso zotsutsana ndi dzimbiri.
