I-valve yomoya eyi-double orifice ehlanganisa kokubili ukusebenza kwe-orifice enkulu kanye ne-orifice encane ngaphakathi kweyunithi eyodwa. I-orifice enkulu ivumela umoya ukuthi ukhishwe ohlelweni ngesikhathi sokugcwaliswa kwepayipi futhi ibuyisele umoya ohlelweni noma nini lapho kuba khona ukucindezela komkhathi ongaphansi. Umoya uyakhishwa. kusuka ohlelweni kuze kube yilapho amanzi engena ku-valve bese ephakamisa ukuntanta esihlalweni sayo, eqinisekisa uphawu oluqinile. Uma kwenzeka kuba nomfutho we-sub-atmospheric ohlelweni, izinga lamanzi liyehla libangele ukuba i-float iwe esihlalweni sayo futhi ivumele ukungena umoya.
