1. Nzvimbo
Iwo maDN mitsara anosanganisira DN15mm~600mm(1/2”~24”) uye PN siyana kubva kuPN1.6MPa~20MPa(ANSI CLASS150~1500) yakarukwa, yakarukwa, BW uye SW swing uye yekusimudza cheki vharuvhu.
2.Kushandisa:
2.1 Iyi valve ndeyekudzivirira yepakati inoyerera ichidzokera kumashure mupombi system.
2.2 Valve zvinhu zvinosarudzwa zvinoenderana nepakati.
2.2.1WCB vharuvhu yakanakira mvura, chiutsi uye mafuta svikiro nezvimwe.
2.2.2SS vharafu inokodzera ngura yepakati.
2.3 Tembiricha:
2.3.1Common WCB inokodzera tembiricha -29℃ ~+425℃
2.3.2Alloy valve inokodzera tembiricha≤550℃
2.3.3SS vharafu inokodzera tembiricha-196 ℃ ~+200℃
