Mavavu agulugufe okhala ndi PTFE amagwiritsidwa ntchito kwambiri pamankhwala, mankhwala, kupanga magetsi ndi mafakitale ena.Mavavuwa amapangidwa makamaka kuti aziwongolera ndi kuwongolera kutuluka kwamadzi owononga kapena owononga.
Kuyika kwa PTFE mkati mwa valavu kumapereka dzimbiri bwino komanso kukana kutentha kwambiri, zomwe zimapangitsa kuti zikhale zabwino kwa mafakitale osiyanasiyana.Maonekedwe opindika a mavavu agulugufewa amawapangitsa kukhala opepuka komanso osavuta kuyiyika pakati pa ma flanges.
Mavavu agulugufe okhala ndi mizere ya PTFE amadziwika chifukwa cha kulimba kwawo komanso zofunikira zocheperako.Mapangidwe a disc a valve amachepetsa chipwirikiti ndikupangitsa kuti ziwonjezeke kwambiri, zomwe zimapangitsa kuti ikhale njira yotsika mtengo yogwiritsira ntchito mafakitale.Mapangidwe ang'onoang'ono a ma valve awa amathandizira kukhazikitsa m'mafakitale ndikusunga malo ofunikira.
Mwachidule, PTFE mizere yopyapyala agulugufe mavavu kupereka njira yothandiza kulamulira dzimbiri ndi abrasive madzimadzi.Kudalirika kwawo, kulimba komanso kuchita bwino kumawapangitsa kukhala abwino kwa mafakitale osiyanasiyana.
Gawani thupi la PTFE valavu yagulugufe yokhala ndi mzere wokwanira kuti igwirizane mosavuta ndikusintha chisindikizo.
