Njengoba igama lisho, i-valve yebhola elintantayo isebenzisa ibhola njengesakhiwo ukuvala ingxenye yesiphambano sepayipi nokumisa ukugeleza koketshezi. Isici esiyinhloko se-valve yebhola entantayo ukuthi ngenxa yokuthi ibhola lintula isakhiwo sokulibamba, lintanta oketshezini futhi libanjwe izihlalo zamavalvu endaweni. Ibhola le-valve yebhola elintantayo alivimbeli noma iyiphi enye ingxenye, ngakho-ke uma i-valve ivaliwe futhi i-medium icindezelwa ohlangothini olulodwa lwe-valve (enhla nomfudlana), ibhola lingakhiqiza ukugudluka okuthile futhi licindezele ngokuqinile endaweni yokuvala ye-outlet. ekugcineni (ezansi nomfula) we-valve, okwenza uphawu lokuphuma. Ngenxa yokuthi kunezinhlobo eziningi ezahlukene zama-valve atholakalayo, kubalulekile ukuqonda ukuhluka kwawo ukuze ukhethe leyo evumelana kangcono nesicelo esiseduze. Ama-valve ebhola antantayo awuhlobo lwe-valve yebhola lapho uhlelo lokuvala lumisiwe. Ngenxa yalokho, anomklamo nokusebenza okulula kakhulu futhi angasetshenziselwa izinhlelo zokusebenza lapho isivinini ekuvuleni noma ekuvaleni ukugeleza, ukukhululeka ekuguquleni isiqondiso sokugeleza, noma ukulula kokufaka kubalulekile. Eminye imiklamo kufanele inakwe uma kunezidingo ezinzima kakhulu ezikhona, njengokubekezelela okuphezulu ezindaweni ezinzima, amazinga okushisa aphezulu, nezingcindezi eziphezulu. Cabangela uhlobo lokubekwa uphawu njengenye into ebalulekile ethonya isinqumo kulezo zimo, futhi mhlawumbe usebenzise umklamo oneziqephu ezimbili noma ezintathu. Inqubo yokukhetha akufanele inikeze izinselele ezinkulu uma izincomo ezishiwo ngenhla zilandelwa. Ukuze ugweme ukuthengwa kabusha noma izindleko ezengeziwe ezihlobene nokushintsha amavalvu angazange ahlangabezane nezidingo zesicelo, kuyalulekwa ukuthi ubonane ne-NTGD valve, umkhiqizi ohlonishwayo wamavalvu ebhola antantayo, noma nini lapho ungabaza.
