Njengethuluzi lokuvula, ukuvala nokulawula ipayipi lokukhipha umoya nothuli, i-ventilation butterfly valve ifanelekela izinhlelo zokukhipha umoya, ukususa uthuli kanye nokuvikela imvelo kwezensimbi, ezimayini, esimendeni, embonini yamakhemikhali kanye nasekukhiqizeni ugesi.

I-veluve ye-ventilation butterfly icutshungulwa ibe yindandatho yokuvala enento efanayo nomzimba we-valve. Izinga lokushisa layo elifanele lincike ekukhethweni kwezinto zomzimba we-valve, futhi ingcindezi evamile ingu-≤ 0.6MPa. Ngokuvamile isebenza kumapayipi ezimboni, ensimbi, ezemvelo kanye namanye omoya wokungenisa umoya kanye nokulawula ukugeleza okuphakathi.

Izici zayo eziyinhloko yilezi::

1. Idizayini entsha nenengqondo, isakhiwo esiyingqayizivele, isisindo esincane kanye nokuvulwa nokuvalwa okusheshayo.

2. I-torque encane yokusebenza, ukusebenza okulula, ukonga abasebenzi futhi inekhono.

3. Izinto ezifanele kufanele zisetshenziswe ukuhlangabezana nezidingo zamazinga okushisa aphansi, aphakathi naphezulu kanye nemidiya egqwalisayo.
