Amuna awiri opangidwa ndi pneumatic bross air ball valve ndi chinthu wamba chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale. Amapangidwa ndi zinthu zamkuwa zapamwamba kwambiri ndipo ali ndi kukana bwino kwa dzimbiri komanso kukana kutentha kwambiri. Valavu iyi imakwaniritsa ntchito yapa-off kudzera muulamuliro wa pneumatic ndipo imakhala ndi mawonekedwe oyankha mwachangu. Kapangidwe kake ndi kakang'ono, kosavuta kukhazikitsa, komanso kosavuta kugwiritsa ntchito. Ma valve awiri aamuna opangidwa ndi pneumatic pneumatic bross airball amatha kugwiritsidwa ntchito kwambiri pamapaipi omwe amanyamula mpweya, zakumwa, ndi media zina, ndikusindikiza bwino komanso kuwongolera madzimadzi. Kudalirika kwake komanso kukhazikika kwake kumapangitsa kuti ikhale imodzi mwa zida zofunika kwambiri pantchito yamakampani.
