Muva nje, sithuthukise i-valve ye-butterfly valve ye-bi-directional yamakhasimende aseJapane, okuphakathi kujikeleza amanzi okupholisa, izinga lokushisa + 5 ℃.

Ikhasimende ekuqaleni lalisebenzisa i-unidirectional butterfly valve, kodwa kunezikhundla ezimbalwa ezidinga ngempela i-valve butterfly e-bi-directional, ngakho ikhasimende lethu lisicele ukuthi siphinde sinikeze i-valve yama-butterfly e-bi-directional wafer kulezi zikhundla ngaphandle kokushintsha ubukhulu bobuso nobuso.

Ngemva kwengxoxo yomnyango wezobuchwepheshe we-THT, sinqume ukusebenzisa isikhunta sokuqala sokuvala esingaqondile ukuze sicubungule i-valve uvemvane evala uphawu kabili.Njengomphumela, siphumelele, i-PN25 positive pressure back pressure 1:1.
