Bupanduluzi:
WZ Series Metal seated OS&Y gate valve ibelesya ductile iron gate iijisi zikobela zya bronze kuti zitanjili maanzi. I OS&Y (Outside Screw and Yoke) gate valve ibelesyegwa kapati muzibelesyo zyakukwabilila mulilo. Kusiyana kupati kuzwa ku NRS (Non Rising Stem) gate valve nkuti stem a stem nut zilabikkwa anze lya valve. Eezi zipa kuti cuube-ube kubona kuti naa vvalavu ilijulidwe naa ilijalidwe, nkaambo bulamfwu boonse bwachisiko bulabonwa aawo vvalavu noijalukide, mpawo ntalisyo tiichilibonyi aawo vvalavu noijalwa. Muchiindi choonse eechi nchintu cheelede kuchitwa muma system aaliboobu kuchitila kuti kube kweendelezya kwakufwambaana kwa system
