Sisenokusoloko sibona oonobumba okanye amanani kumzimba wevalvu, kwaye abahlobo abangaqhelananga nesivalo basenokubhidaniswa ngaba nobumba namanani.Logama ufunda kangangexesha elithile, uya kufumanisa ukuba oonobumba kunye namanani baluncedo kakhulu.

Umzekelo, kumzimba wevalvu yentsimbi engenastainless, amagama athi CF8 / CF8M ahlala ebonwa.La magama amele imathiriyeli yevalvu yomzimba.I-CF8 / CF8M yimigangatho yaseMelika.Iikhowudi zabo zentsimbi zasekhaya ezihambelanayo ziphonswa insimbi engenasici i-304 kunye ne-stainless steel 316, kunye.Urhulumente waseTshayina ufuna ukuba izixhobo zomzimba zevalvu (ezifana neCF8 / CF8M), idiameter yegama (njenge-DN150 DN60), uxinzelelo lwegama (njenge-PN16, PN40), inombolo yesithando somlilo (njenge-7538), njl., ilingana ne-7538 ukubonelela abasebenzisi ngolwazi lweparamitha yesivalo kunye nobungqina besazisi, nto leyo enceda abasebenzisi ukuba balawule ngcono ukusetyenziswa kweevalvu.
