Mtedza wa tsinde wa valavu yachipata chokwera imayikidwa pa chivundikiro cha valve kapena bulaketi.Vavu ikatsegulidwa ndi kutsekedwa, tsinde limakwezedwa ndikutsitsidwa ndikuzungulira mtedza wa screw.Mu dongosolo ili, ulusi wa tsinde la valve sichimalumikizana ndi sing'anga, ndipo sichimawonongeka mosavuta ndi sing'anga, ndipo panthawi imodzimodziyo, ndi yopindulitsa ku mafuta a ulusi wa tsinde la valve.
Ubwino wa valve ya gate:
1) Small madzimadzi kukana;
2) torque yaying'ono yofunikira pakutsegula ndi kutseka;
3) Itha kugwiritsidwa ntchito pa payipi ya mphete pomwe sing'anga imayenda mbali ziwiri, ndiye kuti, kuwongolera kwa sing'anga sikuletsedwa;
4) Mukatsegulidwa kwathunthu, Kusindikiza kumasokonekera ndi sing'anga yogwira ntchito ndipo ndi yaying'ono kuposa valavu yapadziko lonse lapansi.5) Maonekedwewo ndi osavuta, ndipo njira yopangira ndi yabwino.
6) Kutalika kwa kamangidwe kumakhala kochepa.Nthawi zambiri, payipi ndi kukula mwadzina lalikulu kuposa DN50 ntchito ngati chipangizo kudula sing'anga.
Amagwiritsidwa ntchito ngati cutoff ndi zida zosinthira pamitundu yosiyanasiyana yamadzi ndi ngalande pepeline pomanga, mankhwala, mankhwala, nsalu, sitima ndi mafakitale ena.Vavu ya Zhongfa imatha kupereka ma valve olowera pachipata cha OEM & ODM ndi magawo ena ku China.Nzeru ya valavu ya Zhongfa ndikufunafuna zinthu zamtengo wapatali zokhala ndi ntchito yabwino kwambiri yokhala ndi mtengo wapamwamba kwambiri.Zogulitsa zonse za valve zimayesedwa kawiri musanatumize kuti zitsimikizire mtundu wa mankhwala.Takulandirani kudzayendera mafakitale athu.Tidzawonetsa Luso la mavavu.
