Pamene mpweya ukusefukira m'dongosolo, mpweya umakwera pamwamba pa payipi ndipo pamapeto pake udzasonkhana pamalo okwera kwambiri a dongosolo, ndipo valavu yotulutsa mpweya nthawi zambiri imayikidwa pamalo apamwamba kwambiri a dongosolo.

Pamene mpweya umalowa mu valve yotulutsa mpweya ndikusonkhanitsa mu valve yotulutsa mpweya Kumtunda, pamene mpweya wa valve ukuwonjezeka, kuthamanga kumawonjezeka. Kuthamanga kwa mpweya kukakhala kwakukulu kuposa kuthamanga kwa dongosolo, mpweya umapangitsa kuti madzi omwe ali m'bowo agwe. Mpira woyandama umatsika ndi mulingo wamadzi ndikutsegula doko la utsi. Gasi ikatha, madziwo amakwera ndipo mpira woyandama umakweranso, doko lotulutsa mpweya limatsekedwa. Momwemonso, pamene kupanikizika koipa kumapangidwa m'dongosolo, mlingo wa madzi muzitsulo za valve umatsika ndipo khomo lotulutsa mpweya limatsegulidwa. Popeza mphamvu ya kunja kwamlengalenga ndi yaikulu kuposa mphamvu ya dongosolo panthawiyi, mpweya udzalowa mu dongosolo kudzera pa doko lotayirira kuti muteteze kuvulaza kwa kupanikizika koipa. Ngati boneti pa thupi la valavu ya valavu yotulutsa mpweya yatsekedwa, valavu yotulutsa mpweya imasiya kutopa. Nthawi zambiri, boneti liyenera kukhala lotseguka.

Valve yotulutsa imatha kugwiritsidwanso ntchito limodzi ndi valavu yodzipatula kuti ithandizire kukonza valavu yotulutsa mpweya.

Kutentha, ma boilers, zotenthetsera madzi a solar, makina operekera madzi, zida zothandizira, ndi zina zambiri.
