WZ Series Metal seated OS&Y gate valve
Deskripsyon:
WZ Series Metal seated OS&Y gate valve i servi en gate feray duktil ki abrit bann bag bronz pou asir en sele etann. OS&Y (Outside Screw and Yoke) gate valve i prensipalman ganny servi dan bann sistenm sprinkler proteksyon kont dife. Diferans prensipal avek en standar NRS (Non Rising Stem) gate valve se ki stem ek stem nut i ganny mete an deor lekor valv. sa i fer li fasil pou vwar si sa valv i ouver ou fermen, vi ki preski tou longer sa brans i vizib ler sa valv i ouver, tandis ki sa brans i nepli vizib ler sa valv i fermen. an zeneral sa i en legzizans dan sa bann kalite sistenm pou asir en kontrol vizyel rapid lo stati sistenm

Tre:
Wedge nut: Wedge nut i ganny fer avek alyaj kwiv avek abilite lubrifikasyon ki donn en konpatibilite optimal avek brans an feray.
Wedge: Sa wedge i ganny fer avek feray duktil avek bann bag fasad an alye kwiv ki ganny masinnen pour asir en bon sirfas pour asir en kontak optimal avek bann bag sez lekor. Bann bag fasad wedge i ganny masin avek presizyon e byen atase avek sa wedge. Bann gid dan sa wedge i asir en fermtir iniform nenport ki presyon o. napa delo stagnant oubyen lenpirte ki kapab kolekte. Sa wedge i konpletman proteze par en revwar epoxy ki'n ganny atase avek fizyon.
