Ivalvu yebhabhathaneYakhiwe ngomzimba ofana nendandatho lapho kufakwa khona isihlalo/i-liner ye-elastomer efana nendandatho. I-washer eqondiswa nge-shaft ijika ngokunyakaza okujikelezayo okungu-90° iye ku-gasket. Kuye ngenguqulo nosayizi ojwayelekile, lokhu kwenza ukucindezela kokusebenza kufike ku-25 bar kanye namazinga okushisa afinyelela ku-210 °C kuvalwe. Ngokuvamile, lawa ma-valve asetshenziselwa uketshezi oluhlanzekile ngomshini, kodwa angasetshenziswa futhi ekuhlanganisweni kwezinto ezifanele ngaphandle kokudala izinkinga zemidiya ehlukumezayo noma amagesi kanye nomhwamuko.
Ngenxa yobuningi bezinto zokwakha, ivalvu yebhabhathane ihambisana kahle nomhlaba wonke, isibonelo ngezicelo eziningi zezimboni, ukwelashwa kwamanzi/amanzi okuphuza, imikhakha yasogwini kanye neyasogwini. Ivalvu yebhabhathane ivame ukuba yindlela engabizi kakhulu kunezinye izinhlobo zamavalvu, lapho kungekho zidingo eziqinile mayelana nokushintsha kwemijikelezo, ukuhlanzeka noma ukunemba kokulawula. Ngosayizi omkhulu ongaphezu kwe-DN 150, ivame ukuba yivalvu yokuvala kuphela esasebenza. Ngezidingo eziqinile maqondana nokumelana namakhemikhali noma ukuhlanzeka, kukhona ithuba lokusebenzisa ivalvu yebhabhathane enesihlalo esenziwe nge-PTFE noma i-TFM. Uma ihlanganiswa nediski yensimbi engagqwali ehlanganisiwe ye-PFA, ifaneleka kakhulu embonini yamakhemikhali noma ye-semiconductor; futhi ngediski yensimbi engagqwali epholishiwe, ingasetshenziswa futhi emkhakheni wezokudla noma wemithi.
Kuzo zonke izinhlobo zamavalvu ezichaziwe,I-CZITinikeza izesekeli eziningi ezenziwe ngokwezifiso zokwenza ngokuzenzakalelayo kanye nokwenza ngcono izinqubo. Isikhombisi sendawo sikagesi, izilawuli zesikhundla kanye nezinqubo, izinhlelo zezinzwa namadivayisi okulinganisa, zifakwa kalula nangokushesha kubuchwepheshe bokulawula izinqubo obukhona.
