E sili ona fetaui lelei mo le lapisi pepe o le tele-caliber valve e faʻapipiʻi i le itu o le paipa.I totonu o le butterfly valve body cylindrical channel, tisiki tisiki faataamilo i le axis o le taamilosaga, suiga Angle i le va o le 0 ° ~ 90 °, liliu i le 90 °, o le valve ua tatala atoatoa le setete.O lona fausaga e faigofie, taugofie, fetuutuunai laina e tele.
Butterfly valve fa'amaufa'ailoga o le pa'u e fai ma sui, e mamao mai le afa polo valve, polo valve, faitoto'a valve uamea fa'amaufa'ailoga faigata.O le afa o le polo valve pe a uma ona faʻaaogaina umi, o le nofoa e maua ai foʻi uiga o le ofuina, o le a faʻaauau pea ona faʻaaogaina, e ala i le fetuunaʻi o le aʻa ma le faʻapipiʻiina i le faagasologa o le tatalaina ma le tapunia o le valve naʻo le 90 °, sa i ai faʻailoga o le liki, compression packing gland bolts toe itiiti, afifiina e mafai ona iloa e aunoa ma le leakage, ae o le isi o loʻo i ai pea le malosi valve leak itiiti, leaks tetele i le valve.
O loʻo i ai se faʻatusatusaga o le valve butterfly e tolu faʻamaufaʻailoga faʻamaufaʻailoga faʻamaufaʻailoga pepe, valve tino ma le nofoa mo vaega tuʻufaʻatasia, nofoa faʻamaufaʻailoga luga o luga ole vevela vevela, mea faʻapipiʻi faʻafefete.Faʻamau faʻamaufaʻailoga mama faʻapipiʻi faʻapipiʻi i luga o le valve plate, o lenei valve butterfly pe a faʻatusatusa i le valve butterfly masani e maualuga le vevela, gaioiga mama, leai se faʻalavelave tatala ma tapuni, tapunia ma le torque o le masini feaveaʻi e totogi ai le faʻamaufaʻailoga, faʻaleleia le faʻamaufaʻailogaina o le valve butterfly ma faʻaumiumi le lelei o le ola tautua.
