Standard AISI304 kapena 316 chipata chachitsulo chosapanga dzimbiri chimapukutidwa ndikupukutidwa bwino ngati galasi, chomwe chingapewe kuwonongeka kwa kulongedza ndi mpando kudzera pakutsegula kapena kutseka ndikupanga chisindikizo chachikulu.Pansi pa m'mphepete mwa chipata amapangidwa ndi bevel, kotero kuti amadula zolimba kuti asindikize kwambiri pamalo otsekedwa.Chitetezo cha mpeni chingaperekedwe kuti chitetezedwe ku fumbi.
Pali 3 mbali monga pansipa:
1. Mpando wokhazikika wa NBR, EPDM, umapezekanso ku PTFE, Viton, Silicone etc. Mapangidwe apadera omwe amatseka chisindikizo mkati mwa thupi la valve ndi mphete yosapanga dzimbiri.Nthawi zambiri ndi mapangidwe a chisindikizo cha unidirectional, ndi chisindikizo cha bidirectional monga momwe akufunira.
2. Zigawo zingapo zonyamula zoluka zokhala ndi njira yosavuta yolongedzera zopangitsa kuti zisindikize zolimba.Zopezeka mumitundu yosiyanasiyana: Graphite, PTFE, PTFE+KEVLAR etc.
3. Chingwe chowongolera pa thupi la valve chimapangitsa kuti chipata chiziyenda bwino, ndipo chipika cha extrusion chimatsimikizira kuti chisindikizo chikugwira ntchito bwino.
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%.
