Valve yamanja ndi mtundu wamba wa valve womwe umagwiritsidwa ntchito pazida ndi zida, zomwe zimagwiritsidwa ntchito pogwiritsa ntchito chogwirira ndi pamanja. General handle,gudumu lamanjaKuzungulira kozungulira komwe kumayendera kufupi ndi thorium, mobwerera kumbuyo komwe kumatsegulira kuwongolera kozungulira. Koma valavu ina kutsegula ndi kutseka mbali ina, pamaso opaleshoni ayenera kulabadira kuyang'ana kutsegula ndi kutseka pambuyo ntchito.
Kukula kwa valavu yamanja, chogwirira ndigudumu lamanjaamapangidwa ndi munthu wabwinobwino. Choncho, kugwiritsidwa ntchito kwa valve kumatchulidwa: wogwiritsa ntchito saloledwa kugwiritsa ntchito lever ndi wrench yaitali kuti atsegule ndi kutseka valve. Pa nthawi yomweyo, kutalika kwa chogwirira ndi awiri a handwheel ndi zosakwana 320mm, munthu mmodzi yekha amaloledwa ntchito. The handwheel ndi m'mimba mwake wofanana kapena kupitirira 320mm amalola anthu awiri ntchito pamodzi, kapena amalola munthu m'modzi ntchito ndi lever yoyenera (utali wonse ndi zosaposa 0.5m). Koma ma valve a diaphragm, ma valve opanda zitsulo amaletsedwa kugwiritsa ntchito lever kapena spinner yaitali, ndipo musalole mphamvu yaikulu, yowonjezereka kuti itseke valavu.
Ogwiritsa ntchito ena amagwiritsa ntchito lever ndi sipinari yayitali kuti agwiritse ntchito valavu yamanja, ndipo mphamvu yotseka ndiyo yabwino, sichoncho. Izi zipangitsa kuwonongeka kwa valve msanga komanso kuyambitsa ngozi. Zochita zimasonyeza kuti: kuwonjezera percussive dzanja gudumu, mwadzidzidzi lalikulu kwambiri mosavuta kuwononga ntchito ya valavu handwheel, chogwirira, tsinde ndi kusindikiza pamwamba abrasions, ndipo ngakhale wosweka kusindikiza pamwamba. Chachiwiri, agudumu lamanja, chogwirira chowonongeka kapena chosowa, chiyenera kudzazidwa mwamsanga, osaloledwa kugwiritsa ntchito ma wrenches.
Mavavu monga ma valve pachipata ndi ma valve a globe ayenera kutembenuzidwira ku 1/4 ~ 1/2 pamene akutseka kapena kutsegula pamwamba (ie, malo otsika pansi kapena pamwamba pakufa), kotero kuti ulusi ukhoza kusindikizidwa bwino, kotero kuti ukhoza kufufuzidwa mu ntchito yopindulitsa kuti usamangidwe mwamphamvu kwambiri ndikuwononga valavu.
Mavavu akulu akulu agulugufe, mavavu a geti ndi mavavu odulidwa-amaperekedwa ndi ma bypass valves. Ntchito ya valve bypass ndikulinganiza kusiyana kwa kuthamanga kwa kutumiza ndi kutumiza kunja, ndi kuchepetsa nthawi yotsegulira. Tsegulani valavu yodutsa poyamba, ndiyeno mutsegule valavu yayikulu.
