1.Working auala

E tusa ai ma le eseese o ala o faasalalauga galue, e tatau ona filifili mea ma lelei tetee corrosion. Mo se faʻataʻitaʻiga, afai o le ala o le vai masima poʻo le suasami, e mafai ona filifilia le alumini apamemea valve disc; Afai ole ala ole malosi malosi po'o le alkali, e mafai ona filifilia le tetrafluoroethylene po'o le fluororubber fa'apitoa e fai ma mea mo le nofoa valve.

2.Working mamafa ma le vevela

pa'u fa'amaufa'ailoga ole pepee manaʻomia le faʻagaioia masani i totonu o le mamafa o galuega ma le vevela, o lea e tatau ai ona filifili mea e lava le malosi ma le vevela.

3. Tulaga o le siosiomaga

Mafaufau i tulaga o le siosiomaga o loʻo i ai le valve, e pei o le susu, masima masima, ma isi, ma filifili mea talafeagai. 

4.Valve mea tino

O mea o le tino valve oflange butterfly valveaofia ai le uʻamea lafo uʻamea, uʻamea ductile, lafo uamea, uamea stainless, ma isi. Faatasi ai ma i latou, uamea stainless e sili ona lelei faatinoga, ae o le tau e fai si maualuga. Afai o loʻo i totonu o se siʻosiʻomaga maualalo, o le faʻatinoga o mea uʻamea uʻamea e mafai ona faʻatusatusa i le mea o le uʻamea uʻamea, ma o le tau o le faʻaaogaina o mea uʻamea ductile e maualalo.

5.Valve nofoa mea

O mea nofoa oalavai pepepe anufeaofia ai pa'u ma fluoroplastics. E mafai ona fa'aogaina nofoa valve pa'u i fa'asalalauga vaivai ma alkaline e pei o vai, ausa, ma le suāu'u, fa'atasi ai ma fa'amaufa'ailoga lelei; E fa'aogaina nofoa valve Fluoroplastic i ala fa'asalalau maualuga.

6. Butterfly disc material

O mea fa'apipi'i pepe mo valve butterfly tusi e masani lava ona aofia ai le u'amea fa'ama'i ma le sila. O nisi taimi, ina ia mafai ona faʻafetaui i siosiomaga faʻasalalauga sili atu ona faigata, e manaʻomia le afifiina o le butterfly disc i le kelu poʻo le PTFE mea.

7.Valve mea faʻamau

O le tele oi latou e faia i mea u'amea u'amea, ma tulaga fa'apitoa e mafai ona fa'atulagaina e tusa ai ma mana'oga.

8.Drive meafaitino

E lua auala autu o le faʻaogaina o le tusi lesona, o le au ma le anufe. O mea e faʻaaogaina e aofia ai le uʻamea, carbon steel, stainless steel, alumini alumini, ma isi; O mea o le ulu o anufe e tele lava ina lafo u'amea.

I se aotelega, o meafaitino filifilia lelei oalavai butterfly manuale tatau ona mafaufau loloto i mea taua e pei o le galue, mamafa galue ma le vevela, tulaga o le siosiomaga, faʻapea foʻi ma mea e faʻaogaina ai le tino valve, nofoa valve, butterfly disc, ma valve shaft. Le filifiliga sa'o mea e mafai ona mautinoa le faagaoioiga masani ma le ola tautua oalavai butterfly.
