E tusa ai ma le fomu fesoʻotaʻiga flange, o lele tino o le valve valvee masani lava ona vaevaeina i: ituaiga o fafie A, ituaiga LT, flange tasi, flange lua, flange U ituaiga.
O le Wafer type A o se pu e leai se filo, LT type 24" i luga aʻe o faʻamatalaga tetele e masani ona faʻaogaina le sili atu le malosi U-ituaiga valve tino e fai ai fesoʻotaʻiga filo, o le pito o le paipa e manaʻomia le faʻaogaina o le LT type.
E tusa ai ma le faʻamaufaʻailoga fausaga, o lele tino o le valve valvee mafai ona vaevaeina i le tino vulcanized pa'u (tino nofoa e le suitulaga), vaelua le tino o le valve (e masani lava ma le nofoa fa'afefete), ma le tino o le nofoa e mafai ona sui (ma le nofoa malo ma le nofoa malu).
O mea a le tino e masani ona faʻaaogaina i valve butterfly concentric e masani lava: lafo uʻamea, uʻamea ductile, tuʻu uʻamea tino, lafo tino uʻamea, lafo tino apamemea, lafo alumini tino ma lafo super duplex uamea tino.
Tu'u u'amea: O mea sili ona taatele i totonu o le valve butterfly, e masani ona faʻaaogaina i totonu o le vai, faigofie ona pala, ola puupuu, taugofie.
Tu'u u'amea: lafo u'amea e talafeagai mo le mamafa o le PN ≤ 1.0MPa, vevela -10 ℃ ~ 200 ℃ o le vai, ausa, ea, kesi ma le suauu ma isi ala o faasalalauga.Efuefu lafo uʻamea masani faʻaaogaina tulaga ma togi o: GB / T 12226, HT200, HT250, HT300, HT350.
u'amea u'amea: I totonu o le butterfly valve fa'atinoga e fa'atusalia i le carbon steel se mea, e masani ona fa'aaogaina i le paipa vai, ae fa'apea fo'i i le taimi nei o le vai i luga o le fa'aogaina o le tele o mea.
uʻamea uʻamea: talafeagai mo PN ≤ 2.5MPa, vevela -30 ~ 350 ℃ vai, ausa, ea ma suauu ma isi ala o faasalalauga.Fa'aaoga masani ma togi o: GB / T12227: 2005 QT400-15, QT450-10, QT500-7;EN1563 EN-GJS-400-15, ASTM A536,65 45-12, ASTM A395,65 45 12.
Carbon sila: E mafai foi ona faʻaaogaina i le vai, carbon steel butterfly valve o loʻo i ai le maualuga o le vevela ma le faʻamalosi malosi, faʻamaufaʻailoga faʻamaufaʻailoga faʻamaufaʻailoga sili atu ma mea uamea carbon.
Uamea Carbon: E talafeagai mo le mamafa PN ≤ 3.2MPa, vevela -30 ~ 425 ℃ vai, ausa, ea, hydrogen, amonia, nitrogen ma suauu oloa ma isi auala.Fa'aaoga masani togi ma tulaga o ASTM A216 / 216M: 2018WCA, WCB, ZG25 ma u'amea maualuga 20, 25, 30 ma le u'amea faumea faumea 16MN.
u'amea u'amea: u'amea u'amea butterfly valves e sili ona lelei 'ele ele ma corrosion tete'e, ma e tele fo'i fa'aaogaina i paipa e mana'omia le pala ma ele tete'e, ma o le tau e fai si maualuga.Faʻatatau i le mamafa o le mamafa PN ≤ 6.4.0MPa, fua o le vevela: -268 ° C i le +425 ° C, masani ona faʻaaogaina i vai, suasami, vailaʻau kemisi, suauʻu ma kesi, vailaʻau, meaʻai.Tulaga masani ma togi: ASTM A351/351M:2018, SUS304,304, SUS316, 316
u'amea apamemea: apamemea apamemea butterfly valve e talafeagai mo PN ≤ 2.5MPa vai, suasami, okesene, ea, suauʻu ma isi ala, faʻapea foʻi ma ala o le ausa i le vevela o le -40 ~ 250 ℃, faʻaaoga masani togi mo ZGnSn10Zn2 (apa apamemea. ), H62, Hpb59-1 (apa), QAZ19-2, QA19-4 (apamemea alumini).Tulaga masani ma togi: ASTM B148:2014, UNS C95400, UNS C95500, UNS C95800;ASTM B150 C6300.
