-Kusanthula kwamasewera. Gulu la QC limayang'ana zinthu zomwe zimaponyedwa ndi zinthu kuchokera ku maonekedwe, makulidwe a khoma, kuchuluka, kukula ndi lipoti lachidziwitso choyambirira kuchokera ku foundry malinga ndi mfundo za mayiko kuti apewe osayenera.
-Kuwunika makina. Panthawi imeneyi, gulu la QC lidzayang'ana kulondola kwa makina, kuyang'ana maso ndi maso, kubowola flange kuti mupeze mavuto omwe angakhalepo mwamsanga.
-Kuwunika kwa msonkhano. Pambuyo pa msonkhano, QC idzachita mayeso onse ku valve. Kuyang'ana m'maso kumaphatikizapo kuyeretsedwa kwa chipinda chamkati, maonekedwe owala ndi aukhondo, ndi zizindikiro zomveka bwino m'thupi. Kuyang'ana kukula kumakhala ndi mawonekedwe a nkhope ndi maso, gawo lofunikira kwambiri pakutha kwa kulumikizana. Kuyesa kupanikizika kumaphatikizapo kuyesa kwa hydrostatic kwa kusindikiza ndi kuyesa kwa thupi ndi mpweya mpaka kusindikiza.
--Dimension Checking: QC idzayesa kubowola kwa flange molingana ndi ANSI B 16.5 kapena zofunikira zina. Kukula kwa nkhope ndi nkhope kumangotengera ANSI B 16.10 kapena muyezo wina wofunikira.
Kutalika kwa mavavu ndi kukula kwa magudumu amanja monga momwe zojambula zaumisiri zimavomerezera pa mgwirizano.
- Mayeso a Hydraulic ndi Mayeso a mpweya. QC idzayesa kutayikira kwa chisindikizo, mpando wakumbuyo ndi Shell mosamalitsa malinga ndi API598 kapena EN1226 kapena mulingo wina wogwirizana pa mgwirizano. Ndondomeko ndi yokhazikika ndipo zotsatira zopumula zimanenedwa.
-Kupenta & Kulongedza. Mtundu wa penti ndi kupopera mbewu mankhwalawa zidzawunikidwa. QC idzaonetsetsa kuti kulongedza katundu ndi pempho la mgwirizano. Valavu yoyera imayikidwa mwadongosolo mubokosi lolimba lamatabwa lokhala ndi chizindikiro chotumizira bwino podzaza zinthu zofewa zokwanira kuti zisagundane.
- Malipoti. Pambuyo pa Kuyesa, mupeza lipoti latsatanetsatane kuchokera ku zidutswa zomwe zimayang'ana zomwe zamalizidwa musanatumize. Mayeso a Hydraulic ndi mayeso a mpweya okhala ndi zithunzi ndi makanema aziwonetsa makasitomala kuti atsimikizire musanatumizidwe.
Zaka zambiri zokumana nazo zotumizira ma valve kunja ndikuwongolera mosalekeza, DEYE Quality Control System ipitiliza kugwira ntchito molimbika ndikukhala yangwiro.
