2.1 ʻO kēia valve ka mea e pale ai i ke kahe ʻana o ka waena i hope i ka ʻōnaehana paipu.
2.2 Koho ʻia nā mea valve e like me ka waena.
2.2.1WCB kiwi he kūpono no ka wai, mahu a me ka aila waena etc.
He kūpono ka 2.2.2SS valve no ka corrosion medium.
2.3 Ka wela:
2.3.1 He kūpono ka WCB maʻamau no ka mahana -29 ℃ ~ + 425 ℃
