Ivalve uvemvaneyakha umzimba omise okweringi lapho kufakwa khona isihlalo/umugqa we-elastomer oyindandatho. Iwasha eqondiswa ku-shaft ishintshashintsha ngo-90° inyakaze ingene ku-gasket. Ngokuya ngenguqulo nosayizi wegama, lokhu kuvumela izingcindezi zokusebenza ezifika kubha wama-25 kanye nezinga lokushisa elifinyelela ku-210 °C ukuthi zivalwe. Ezikhathini eziningi, lawa mavalvu asetshenziselwa uketshezi oluhlanzekile, kodwa futhi angasetshenziswa ekuhlanganiseni kwezinto ezifanele ngaphandle kokudala izinkinga kumidiya ehubhuka kancane noma amagesi kanye nomhwamuko.
Ngenxa yobuningi bezinto zokwakha, i-valve ye-butterfly iyahambisana emhlabeni wonke, isibonelo nezicelo eziningi zezimboni, ukwelashwa kwamanzi / okuphuza amanzi, imikhakha yasogwini kanye ne-offshore. I-valve uvemvane futhi ngokuvamile iyindlela engabizi kakhulu kwezinye izinhlobo zama-valve, lapho kungekho khona izidingo eziqinile mayelana nokushintsha imijikelezo, ukuhlanzeka noma ukunemba kokulawula. Kumasayizi amakhulu okuzisholo angaphezu kwe-DN 150, ngokuvamile iyona kuphela ivalvu yokuvala esakwazi ukusebenza. Ukuze uthole izimfuno eziqinile maqondana nokumelana namakhemikhali noma inhlanzeko, kunethuba lokusebenzisa i-valve uvemvane enesihlalo esenziwe nge-PTFE noma i-TFM. Ngokuhambisana ne-PFA encapsulated stainless steel disc, ifanele imidiya enolaka kakhulu embonini yamakhemikhali noma ye-semiconductor; futhi ngediski yensimbi engagqwali epholishiwe, ingasetshenziswa futhi emkhakheni wokudla noma wokwenza imithi.
Kuzo zonke izinhlobo ze-valve ezishiwo,CZITinikeza izesekeli eziningi ezenziwe ngezifiso zokuzenzakalela kanye nokwenza kahle kwenqubo. Electr. inkomba yendawo, izilawuli zesikhundla nezilawuli zenqubo, amasistimu wezinzwa kanye namadivayisi wokulinganisa, afakwa kalula futhi ngokushesha, alungiswe futhi ahlanganiswe kubuchwepheshe bokulawula inqubo obukhona.
