Ivalvu yesango lomoyaluhlobo lwevalvu yokulawula esetyenziswa kakhulu kwicandelo lemizi-mveliso, eyamkela iteknoloji yomoya ephucukileyo kunye nolwakhiwo lwesango, kwaye ineenzuzo ezininzi ezikhethekileyo. Okokuqala, ivalvu yesango lomoya inesantya sokuphendula ngokukhawuleza, kuba isebenzisa isixhobo somoya ukulawula ukuvulwa nokuvalwa kwevalvu, enokwenza ngokukhawuleza isenzo sokutshintsha, ngaloo ndlela iphucula ukusebenza kakuhle. Okwesibini, ukutywinwa kwevalvu yesango lomoya kulungile, kwaye kwamkelwa isakhiwo esikhethekileyo sokutywinwa phakathi kwesango kunye nesihlalo, esinokuthintela ngokufanelekileyo ukuvuza kwaye siqinisekise ukhuseleko lwenkqubo.

Ukongeza, iivalvu zesango lomoya zinika ukuqina okuphezulu kunye nokuthembeka. Inesakhiwo esilula, iinxalenye ezimbalwa, kwaye ayichaphazeleki lula, ngoko ke inobomi obude benkonzo. Kwangaxeshanye, ngenxa yokusetyenziswa kwesixhobo somoya, ukusebenza kuyaguquguquka kwaye kulula, kwaye akukho mzamo mkhulu ufunekayo ukulawula ukuvulwa nokuvalwa kwevalvu, nto leyo enciphisa amandla okusebenza omqhubi. Ukongeza, ivalvu yesango lomoya ikwanayo nenzuzo yokuba neqondo eliphezulu lokuzenzekelayo, elinokudityaniswa nenkqubo yolawulo ukuze kufezekiswe ulawulo oluzenzekelayo kunye nokuphucula ukusebenza kakuhle kwemveliso.

Umgaqo wokusebenza we-pneumaticivalvu yesangongolu hlobo lulandelayo: xa isixhobo somoya sifaka uxinzelelo lomoya, ivalvu yomoya ithumela umoya ocinezelweyo kwigumbi lomoya emzimbeni wevalvu, ukuze uxinzelelo kwigumbi lomoya lunyuke, kwaye isango linyuke phantsi kwesenzo soxinzelelo, ngaloo ndlela livula ivalvu; Xa isixhobo se-pneuma ™tic siyeka ukusebenzisa uxinzelelo lomoya, uxinzelelo kwigumbi lomoya luyancipha, kwaye iram ihla phantsi kwamandla esihlalo, ivala ivalvu. Ngokulawula isixhobo somoya ukuba sisebenzise kwaye siyeke ukusebenza koxinzelelo lomoya, ukuvulwa nokuvalwa kwevalvu kunokulawulwa.

Ngamafutshane, ivalvu yesango lomoya ineengenelo zokuphendula ngokukhawuleza, ukuvala okuphezulu, ukuqina nokuthembeka, ukusebenza lula kunye nokuzisebenzela okuphezulu. Isetyenziswe kakhulu kwiindawo ezininzi, ezifana neekhemikhali, umbane, ipetroli, isinyithi kunye neminye imboni, ibonelela ngesisombululo esisebenzayo sokulawula ulwelo kwinkqubo yemveliso.
