Ma valve amagalimoto amayikidwa mkati mwa mita ya gasi.Kawirikawiri, pali mitundu itatu ya mamita a gasi apanyumba: 1. valve yotseka yotseka;2. valavu yotseka mpweya wabwinobwino;3. valavu yamoto.Kuonjezera apo, ngati mita ya gasi ya mafakitale iyenera kusinthidwa, valve ya mita ya gasi ya mafakitale imafunika.

Nazi mawonekedwe awo ndi kusiyana kwawo:

Valve yotseka yotseka imatha kutsekedwa nthawi yomweyo, chifukwa chake imatchedwa liwiro lake potseka.Valavu yotsekera gasiyi ili ndi zida zoyendetsera magalimoto ndipo imatha kusinthidwa ndi mita ya gasi ya G1.6-G4.Kuphatikiza apo, imatha kuwonjezeredwa ndi ma switch 1 (kapena 2) omaliza (kudutsa ma sign otseguka / otsekedwa-pamalo).

Valavu yotsekera yodziwika bwino ndi yaying'ono poyerekeza ndi valavu yotsekera yotseka, kotero siyingawonjezedwe ndi kusintha komaliza.Vavu iyi Ndi valavu yoyendetsera galimoto yotseka, imagwiranso ntchito pamamita a gasi a G1.6-G4.

Valavu ya mpira wa mita ya gasi ingagwiritsidwe ntchito ndi kuthamanga kwapamwamba.Ndi valavu yoyendetsa giya ndipo imatha kutengera kuchuluka kwa mita ya gasi, kuchokera ku G1.6 mpaka G6.Itha kuwonjezeredwa ndi 1 kapena 2 zosintha zomaliza.Kuphatikiza apo, kapangidwe kake kamamupangitsa kuti azitha kuyesa fumbi.

Valavu yotsekera m'mafakitale imatha kugwiritsidwa ntchito pamamita a gasi okhala ndi kuthamanga kwapamwamba kwambiri.Valavu yamagalimoto yamafakitale imakhala ndi zomangira zoyendetsa, ndipo imagwira ntchito pamamita amafuta a G6-G25.Valavu yamtunduwu imatha kuwonjezeredwa ndi ma switch 1 kapena 2 kumapeto.

Ma valve onsewa amatha kugwiritsidwa ntchito mu gasi wachilengedwe ndi LPG.Ena mwa ma valve amagalimotowa amatha kupangidwa kukhala mavavu akunja, kotero kuti mawonekedwe ake ndi otambalala mokwanira, okwanira kugwiritsa ntchito gasi tsiku lililonse.
