Valves e tusa ai ma ala o faasalalauga talafeagai eseese e filifili ai mea, e mafai ona vaevaeina valve lautele i le vevela masani, vevela maualuga, maualalo le vevela mea filifilia, corrosion tetee mea filifiliga, ae vaevaeina foi i le maualalo o le mamafa, mamafa o le mamafa, maualuga o mea e filifili ai valve, o le autu autu. mea e lafo uʻamea, lafo uʻamea, uʻamea uamea, uʻamea uʻamea, uʻamea vevela uʻamea, maualalo vevela sila, corrosion tetee palasitika filifiliga.

Valve mea masani:
1, togi uʻamea uʻamea uʻamea: uʻamea lafo uʻamea e talafeagai mo le mamafa PN≤ 1.0mpa, vevela o -10 ℃ ~ 200 ℃ vai, ausa, ea, kesi ma le suauu ma isi ala o faasalalauga.O togi masani o le uʻamea lanu efuefu o: HT200, HT250, HT300, HT350.

2, malleable lafo uʻamea: talafeagai mo nominal mamafa PN≤ 2.5mpa, vevela o le -30 ~ 300 ℃ o le vai, ausa, ea ma suauu ala, e masani ona faʻaaogaina ituaiga o: KTH300-06, KTH330-08, KTH350-10.

3, nodular lafo uʻamea valve: talafeagai mo PN≤ 1.6mpa, vevela e -5 ~ 80 ℃ o le vai, ausa, ea ma suauu ma isi ala o faasalalauga.Fa'ailoga masani e fa'aaogaina: QT400-15, QT450-10, QT500-7.
I le va'aiga i le tulaga fa'atekonolosi fa'alotoifale o lo'o i ai nei, o fale ta'itasi ta'itasi e le tutusa, ma e masani ona le faigofie le su'eina o tagata fa'aoga.E tusa ai ma le poto masani, e fautuaina le PN≤ 2.5mpa, o le valve o loʻo faia pea i le sila.

4, u'amea lafo nodular silikon tetee acid: talafeagai mo le mamafa mamafa PN≤ 0.25mpa, vevela i lalo 120 ℃ auala corrosive.

5, valve uamea carbon: talafeagai mo le mamafa o le mamafa PN≤32.0MPa, vevela o le -30 ~ 425℃ o le vai, ausa, ea, hydrogen, amonia, nitrogen ma suauu oloa ma isi ala o faasalalauga.E masani ona fa'aaogaina togi o le WC1, WCB, ZG25 ma le sila 20, 25, 30 ma le u'amea faumea maualalo 16Mn.
