Valavu ya gulugufeIli ndi thupi looneka ngati mphete momwe mpando/chovala chozungulira chooneka ngati mphete chimayikidwamo. Chotsukira chotsogozedwa kudzera mu shaft chimazungulira mozungulira 90° kulowa mu gasket. Kutengera mtundu ndi kukula kwake, izi zimathandiza kuti kupanikizika kogwira ntchito mpaka 25 bar ndi kutentha mpaka 210 °C kuzimitsidwe. Nthawi zambiri, ma valve awa amagwiritsidwa ntchito pa zakumwa zoyera, komanso angagwiritsidwe ntchito m'njira yoyenera popanda kubweretsa mavuto pa zinthu zowononga pang'ono kapena mpweya ndi nthunzi.
Chifukwa cha mitundu yosiyanasiyana ya zipangizo, valavu ya gulugufe imagwirizana ndi anthu onse, mwachitsanzo ndi ntchito zambiri zamafakitale, madzi/madzi akumwa, madera a m'mphepete mwa nyanja ndi m'mphepete mwa nyanja. Vavu ya gulugufe nthawi zambiri imakhala njira yotsika mtengo kuposa mitundu ina ya mavalavu, komwe kulibe zofunikira zolimba zokhudzana ndi kusintha kwa kayendedwe ka magetsi, ukhondo kapena kulondola kowongolera. Mu kukula kwakukulu kopitilira DN 150, nthawi zambiri imakhala valavu yokhayo yotseka yomwe imagwirabe ntchito. Pazofunikira zolimba kwambiri pankhani yotsutsana ndi mankhwala kapena ukhondo, pali kuthekera kogwiritsa ntchito valavu ya gulugufe yokhala ndi mpando wopangidwa ndi PTFE kapena TFM. Kuphatikiza ndi diski yachitsulo chosapanga dzimbiri ya PFA, ndi yoyenera kugwiritsa ntchito zinthu zolimbitsa thupi kwambiri mumakampani opanga mankhwala kapena semiconductor; ndipo ndi diski yachitsulo chosapanga dzimbiri yopukutidwa, ingagwiritsidwenso ntchito mu gawo la chakudya kapena mankhwala.
Kwa mitundu yonse ya ma valve omwe atchulidwa,CZITimapereka zowonjezera zambiri zomwe zakonzedwa kuti zigwiritsidwe ntchito paokha komanso kukonza njira. Chizindikiro cha malo amagetsi, zowongolera malo ndi njira, makina a masensa ndi zida zoyezera, zimayikidwa mosavuta komanso mwachangu muukadaulo womwe ulipo wowongolera njira.
