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 zempushana ukuze aphithize abezindaba. Kukhona ama-manual, igiya le-bevel, i-electric kanye ne-pneumatic actuated actuated.
