Ma valve ochepetsa kuthamanga otsekedwa bwino ayenera kutayikira mkati mwa nthawi yomwe yaperekedwa; pa ma valve ochepetsa kuthamanga otsekedwa ndi chitsulo, kutuluka kwa madzi sikuyenera kupitirira 0.5% ya kuchuluka kwa madzi omwe akuyenda;

Mfundo yachitatu
Kupatuka kwa mphamvu ya kutulutsa kwa mtundu wochita mwachindunji sikupitirira 20%, ndipo mtundu woyendetsedwa ndi woyendetsa supitirira 10%, pamene kuchuluka kwa madzi otuluka kumasintha;

Mfundo Yachinayi
Kupatuka kwa mphamvu ya mpweya wa mtundu wochita mwachindunji pamene mphamvu ya kulowa ikusintha sikupitirira 10%, pomwe kupatuka kwa mphamvu ya mtundu woyendetsedwa ndi woyendetsa ndege sikupitirira 5%;

Mfundo yachisanu
Kupanikizika komwe kuseri kwa valavu yochepetsera kupanikizika kuyenera kukhala kochepera nthawi 0.5 kuposa kupsinjika komwe kusanachitike valavu;

Mfundo yachisanu ndi chimodzi
Valavu yochepetsera kuthamanga ili ndi ntchito zosiyanasiyana ndipo ingagwiritsidwe ntchito pa nthunzi, mpweya wopanikizika, gasi wa mafakitale, madzi, mafuta, ndi zida zina zambiri zamadzimadzi ndi mapaipi.

Mfundo Yachisanu ndi Chiwiri
Mpweya wochepa, waung'ono, komanso wapakati ndi woyenera kugwiritsa ntchito valavu yochepetsera kupanikizika yogwira ntchito mwachindunji;

Mpweya ndi madzi okhala ndi mphamvu yapakati ndi yotsika, mpweya ndi madzi okhala ndi mainchesi apakati ndi ang'onoang'ono ndi zoyenera ma valve ochepetsera mphamvu yamagetsi opangidwa ndi filimu yopyapyala;

Mfundo Yachisanu ndi Chinayi
Mpweya, mpweya, ndi madzi okhala ndi mphamvu zosiyanasiyana, mainchesi, ndi kutentha zingagwiritsidwe ntchito ndi valavu yochepetsera kupanikizika ya piston. Ingagwiritsidwe ntchito pazinthu zosiyanasiyana zowononga ngati yapangidwa ndi chitsulo chosapanga dzimbiri cholimbana ndi asidi;

Mfundo khumi
mpweya wochepa, nthunzi yapakati ndi yaying'ono, mpweya, ndi zinthu zina zolumikizira mpweya ndi zabwino kwambiri pa valavu yochepetsera kupanikizika yoyendetsa ndege;

Mfundo Khumi ndi Chimodzi
kupanikizika kochepa, kupanikizika kwapakati, nthunzi kapena madzi ang'onoang'ono ndi apakati, ndi kuchepetsa kupanikizika kwina kogwirizana ndi mafilimu oyendetsavalavu;

Ma valve ochepetsera kupanikizika amtundu wa piston kapena ma valve ochepetsera kupanikizika amtundu wa pilot bellows nthawi zambiri amagwiritsidwa ntchito pamene kutentha kwa sing'anga kuli kokwera kwambiri;

Mfundo 16
Kawirikawiri amalangizidwa kugwiritsa ntchito valavu yochepetsera kupanikizika yogwira ntchito mwachindunji kapena valavu yochepetsera kupanikizika yoyendetsedwa ndi pilot pamene cholumikiziracho ndi mpweya kapena madzi (madzi);

Mfundo 17
Ngati nthunzi ndi njira yolumikizira, valavu yochepetsera kuthamanga kwa pistoni yoyendetsa kapena mtundu wa bellows ya pilot iyenera kusankhidwa;

Mfundo 18
Valavu yochepetsera kuthamanga nthawi zambiri iyenera kuyikidwa pa payipi yopingasa kuti ikhale yosavuta kugwiritsa ntchito, kusintha, komanso kukonza.
