I-valve yesango yi-valve eqhelekileyo ngakumbi, isetyenziswe ngokubanzi, ikakhulu isetyenziswa kwi-metallgergy kunye neminye imizi-mveliso, ukongeza kusetyenziswa i-valves yesango, ukulungisa ingxaki kunye nophando oluphambili.
Ngokwemilo eyahlukeneyo yesakhiwo samasango, i-valve yesango inokwahlulwa yangamacandelo amabini: Uhlobo lwe-Wedge kunye nohlobo olufanayo.
Ipleyiti yesango ye-Wedge Valve ye-Wedge-imile, kwaye umphezulu wokutywina unomdla kumgca wesitishi, kwaye umtshato phakathi kweplate yesango kunye nesitulo sevali sisetyenziselwa ukutywina (ukuvala). Iplate ye-Wedge inokuba lisango elinye okanye isango eliphindwe kabini.
Umphezulu wokutywina we-valve yesango elifanayo kunye ne-perpendicular ukuya kumgca wesitishi, olwahlulwe lube ziindidi ezimbini: ngaphandle kwendlela yokuvula. Kukho i-RAM ephindwe kabini ngendlela yokubhabha, xa inkunzi yegusha ihla, i-rabge yeenkunzi zeegusha ezimbini ixhonywe kwinqwelomoya, i-ram inyuka inyuka, i-radge yahlulela i-ram yenkunzi yegusha. Xa inkunzi yegusha ingena kwisitulo se-valve ecaleni kwendawo ezimbini ezifanayo ze-valves, uxinzelelo lolwelo lusetyenziselwa ukucinezela i-RAM kwi-valve kwi-valve yokutywina.
Ngokutsho kokuhamba okwahlukileyo kwesiqu se-valve xa kwavalwa isango elivaliweyo kwaye lavalwa, iivalves zesango zahlulwe zangamacandelo amabini: Iivalva ezifihlakeleyo. I-valve stem kunye nesango le-stemp ye-stemp valve inyuka kwaye iwele ngaxeshanye xa kuvulwa okanye ukuvala; Xa i-valve yesango elifihliweyo ye-Stemp ivuliwe okanye ivaliwe, i-valve ijikeleza kuphela, kwaye ukunyuka kwayo kwaye ukuwa kwesiqu se-valve akunakubonwa, kwaye i-vate ye-vate iphakama okanye iwele i-vate. Inzuzo ye-valve yesango le-Stemp kukuba ukuphakama kwesiteshi ukuphakama kunokugwetywa ngokunyuka kwesiqu se-valve, kodwa ukuphakama okuhlala kunqunyulwa. Xa ujongene nesandla okanye isiphatho, jika isiphambuka okanye ukuphatha iwotshi yokuvala ivalve.
