AZ Series Valava ya gede ya OS&Y leyi tshamaka leyi tiyeke
Nhlamuselo:
AZ Series Valava ya gede ya NRS leyi tshameke leyi tiyekei valve ya gede ya wedge na Rising stem (Outside Screw and Yoke)type, naswona yi lulamerile ku tirhisiwa na mati na mati lama nga riki na xihlawuhlawu (thyaka) . Valve ya gede ya OS&Y (Outside Screw and Yoke) yitirhisiwa ngopfu eka tisisiteme ta swifafazeri swo sirhelela ndzilo. Kuhambana lokukulu kusuka eka standard NRS (Non Rising Stem) gate valve hileswaku stem na stem nut swivekiwa ehandle ka miri wa valve. Leswi swiendla leswaku swi olova ku vona loko valve yi pfulekile kumbe yi pfariwile, tani hileswi kwalomu ka ku leha hinkwako ka nsinya ku vonakaka loko valve yi pfulekile, kasi nsinya aya ha vonaki loko valve yi pfariwile. Hi ku angarhela leswi i xilaveko eka tinxaka leti ta tisisiteme ku tiyisisa vulawuri bya mahlo bya xihatla bya xiyimo xa sisiteme..
Swihlawulekiso:
Miri:Ku hava dizayini ya groove,sivela eka thyaka,tiyisisa ku pfariwa loku tirhaka.Hi epoxy coating endzeni,ku fambisana na xilaveko xa mati yo nwa.
Disc:Metal frame na rubber lined,tiyisisa valve sealing na ku fambisana na xilaveko xa mati yo nwa.
Stem:Yi endliwe hi switirhisiwa swa matimba yale henhla,tiyisisa leswaku gate valve yi lawuriwa hiku olova.
Stem nut:Xiphemu xa conection xa nsinya na disc,tiyisisa leswaku disc yi olova ku tirha.
