Mpeni mavavu pachipata makamaka ntchito papermaking, CHIKWANGWANI mankhwala, petrochemical, zitsulo, matope, magetsi, mankhwala zimbudzi.Pazamankhwala ndi zina zogwirira ntchito, valavu ya chipata cha mpeni imapangidwa makamaka ndi thupi la valve ndi chipata.Zida za thupi la valve ndi chitsulo cha ductile, chitsulo cha carbon ndi chitsulo chosapanga dzimbiri, ndipo malo osindikizira amapangidwa ndi mphira wachilengedwe wosamva kuvala, mphira wa fluorine, mphira wa nitrile, ndi mphira wa EPDM.Ndipo kusindikiza zitsulo, kuchokera kumalo owonetserako, valavu ya chipata cha mpeni imakhala ndi mapangidwe ang'onoang'ono, imatenga malo ochepa, ndipo imatha kuthandizira mphamvu ya payipi.
Pali 3 mbali monga pansipa:
1. Pansi pa chipata ndi tsamba lakuthwa lopangidwa ndi U, lomwe limatha kupukuta zomatira pamalo osindikizira ndikudula mwachangu madziwo.wapakati.
2. Pamwamba pa chipatacho chakhala chophwanyidwa bwino ndi kupukutidwa, chomwe sichimangokhala ndi zotsatira zabwino zosindikizira, komanso zimateteza bwino moyo wautumiki wa mpando wonyamula ndi valve.3.Chowongolera pa thupi la valavu chimapangitsa kuti chipata chiziyenda bwino, ndipo chipika cha extrusion chimatsimikizira kusindikiza bwino kwa chipata.
ZFA Valve imagwira mosamalitsa muyezo wa API598, timayesa kukakamiza kumbali zonse za valve 100%, kutsimikizira kutulutsa ma valve 100% kwa makasitomala athu.
Thupi la valavu limatenga zinthu zamtundu wa GB, pali njira 15 kuchokera kuchitsulo kupita ku valavu.
Kuyang'ana kwaubwino kuchokera ku chopanda kanthu kupita kuzinthu zomalizidwa ndikutsimikizika 100%.
ZFA Valve imayang'ana kwambiri kupanga mavavu kwa zaka 17, ndi gulu la akatswiri opanga, titha kuthandiza makasitomala athu kusungitsa zolinga zanu ndi khalidwe lathu lokhazikika.
