isikulufu siphele i-valve yeglobu yensimbi engagqwali
isikulufu siphele i-valve yeglobu yensimbi engagqwalizenziwe ngepulaki egudlukayo njenge-disc ene-flat noma i-conical surface yokuvalwa ukuze ivalwe.Ngokuvamile, ipulaki ixhunywe esiqwini esisetshenziswa isenzo sesikulufu njengomugqa oqondile kusetshenziswa amasondo esandla.Imvamisa, lolu hlobo lwamavalvu embulunga asanda kusetshenziselwa ukuvuleka nokuvala ngokugcwele, alwenzi ukulawulwa kokugeleza.Ingcindezi isuka ku-PN16 iye ku-PN160 futhi izinga lokushisa lokusebenza lisuka ku--29 liye450 degree.Lawa mavalvu embulunga yensimbi asetshenziswa kabanzi kumapayipi e-petroleum, amakhemikhali, ekhemisi, amakhemikhali kanye nezimboni eziyimpushana ukuze aphithize abezindaba.Kukhona ama-manual, igiya le-bevel, i-electric kanye ne-pneumatic actuated actuated.
