Ivalve sisixhobo somatshini sokulawula ukuhamba kolwelo okanye irhasi kwinkqubo yokuqukuqela.Ivalve yokhuseleko kukungaphumeleli kokukhusela, injongo yayo kukuqinisekisa ukhuseleko lombhobho.Umzekelo, ivalve yoxinzelelo loxinzelelo (PRV) njengolunye uhlobo lwevalvu yokhuseleko ekhupha ngokuzenzekelayo imathiriyeli kwisitya soxinzelelo, kwibhoyila, okanye enye inkqubo xa uxinzelelo okanye ubushushu budlula umda obekiweyo.

Imarike yevalve yokhuseleko inokwahlulwa ngezinto eziphathekayo, ubungakanani, ishishini kunye nommandla.Ngokwezixhobo ezahlukeneyo ezisetyenzisiweyo, imakethi yevalve yokhuseleko inokwahlulwa ibe yintsimbi engatyiwa, intsimbi ephoswe phantsi, ubushushu obuphantsi, i-alloy kunye nezinye iintlobo, zingasetyenziswa ngokubanzi kwioyile negesi, amandla, amandla, amanzi kunye nonyango lwamanzi amdaka, imichiza, amayeza. , imigodi yesinyithi, amashishini okutya kunye neziselo.

Indima ebalulekileyo yesivalo sokhuseleko kwinkqubo yoshishino, ukwanda kwemfuno evela kushishino lwe-oyile negesi, kunye nokukhula kokuveliswa kwamandla enyukliya zezona zinto zibalulekileyo zokukhuthaza ukukhula kwemarike yesivalo sokhuseleko.Imarike yevalve yokhuseleko ekhulayo iqhutywa yimfuneko rhoqo yokutshintsha iivalvu zokhuseleko kunye nokusetyenziswa kweeprinta ze-3D kwimigca yemveliso.Kwelinye icala, ixabiso eliphezulu lemveliso liya kuthintela ukwanda kwale marike.

I-COVNA isoloko iphuhlisa kwaye ivelisa izinto ezintsha ukuvelisa nokubonelela ngeevalvu zokhuseleko ezikumgangatho ophezulu ukwandisa imarike yamazwe ngamazwe.
