Amagwiritsidwa ntchito poyang'anira masitepe amadzi a 600 mpaka 1,000MW supercritical (ultra-supercritical) unit ndikukwaniritsa cholinga chokhazikitsira mulingo wamadzi mu thanki yamadzi kudzera m'mabwalo osiyanasiyana.
- Thupi la valavu limagwiritsa ntchito mawonekedwe olimba ndi mphamvu yayikulu ndipo valavu imagwiritsa ntchito mtundu wa plunger wokhala ndi mayendedwe osalala, okhala ndi kapangidwe kake ndi ntchito yopewa chodetsa chaching'ono ndi chinthu chakunja mu chitoliro kuti zisawononge mbali zamkati za valavu.
- Pachimake vavu utenga anapanga vavu pulagi kulamulira madzimadzi mosalekeza. Ilibe discontinuous magawo owongolera masitepe a vala laminated valve.
- Mpando valavu utenga conical kusindikiza ndi valavu pachimake ndi valavu mpando kutengera Stellite aloyi kutsitsi kutsitsi kuwotcherera kuti valavu nawo kukana kumva kuwawa, kukana dzimbiri, odana ndi kukwapula ndi zina, zinapanga odana ndi cavitation ndi kukana kumva kuwawa.
- Manja otsogolera a khola amatha kuteteza thupi la valavu kuti lisawonongeke. Mphete yapadera yomwe imalepheretsa kusayera ndi chinthu china chakunja chimateteza pulagi ya valavu ndi mphete ku dzimbiri.
- Pakatikati pakatundu ka valavu kamakhala ndi mawonekedwe osindikizira ndipo valavu imasindikizidwa bwino ikaponderezedwa.
- Ndi njira yosinthira, woyendetsa yemwe ali ndi valavu akhoza kusinthidwa malinga ndi zomwe ogwiritsa ntchito akufuna.
