Mavavu agulugufe amakhala otseguka ndi kutseka mwachangu kwambiri akamayendetsedwa ndi pneumatic.Diskiyo ndi yopepuka kuposa mpira, ndipo ma valve amafunikira chithandizo chocheperako kuposa valavu ya mpira yofananira.Ma valve a butterfly ndi olondola kwambiri, zomwe zimawapangitsa kukhala opindulitsa pamafakitale.Iwo ndi odalirika ndithu ndipo amafuna chisamaliro chochepa.
1. Kuyatsa / kuzimitsa mosavuta komanso mwachangu ndi mphamvu yochepa.Kukhala ndi mphamvu zochepa zamadzimadzi ndipo kumatha kugwiritsidwa ntchito pafupipafupi.
2. Kapangidwe kosavuta, kakang'ono kakang'ono ndi mawonekedwe afupiafupi a nkhope ndi nkhope, omwe ali oyenera ma valve akuluakulu awiri.
3. Itha kugwiritsidwa ntchito potumiza matope, zamadzimadzi zochepa zimasungidwa pamabowo a chitoliro.
4. Moyo wautali wautumiki.Kuyimilira mayeso makumi masauzande a ntchito zotsegula/zotseka.
5. Ma valve a butterfly ali ndi machitidwe abwino kwambiri.
6. Torque yaying'ono.Kupanikizika kwa ma discs kumbali ziwiri za spindle kumakhala kofanana, kumayambitsa torque yosiyana.Potero, mavavu amatha kutsegulidwa ndi mphamvu zochepa.
7. Kusindikiza kumaso nthawi zambiri kumakhala ndi mphira kapena pulasitiki.Choncho mavavu agulugufe amatha kukhala osindikizidwa bwino pansi pa kupanikizika kochepa.
