WZ Series Metal lungguh OS & Y gate valve
katrangan:
WZ Series Metal lungguh OS & Y gapura tutup nggunakake gapura wesi ductile sing omahé dering tembaga kanggo mesthekake segel watertight. OS & Y (Outside Screw and Yoke) gate valve utamané digunakake ing sistem sprinkler proteksi geni. Bentenane utama saka katup gerbang NRS (Non Rising Stem) standar yaiku batang lan kacang batang dipasang ing njaba awak katup. Iki ndadekake gampang kanggo ndeleng yen tutup mbukak utawa ditutup, amarga meh kabeh dawa batang katon nalika tutup mbukak, nalika gagang ora katon maneh nalika tutup tutup. Umumé, iki minangka syarat ing sistem jinis iki kanggo njamin kontrol visual sing cepet saka status sistem
