Ivalve yokulinganisa emileyo ikwabizwa ngokuba yi-STAD balancing valve okanye i-STAD valve.I-valve yokulinganisa i-Static itshintsha ukuchasana kokuhamba nge-valve ukuphumeza ukulungiswa ngokutshintsha i-gap (ukuvulwa) phakathi kwe-STAD core valve kunye nesihlalo se-valve ye-STAD.Ivalve ye-static balance inokugcina ukuhanjiswa komthamo omtsha wamanzi ngokomlinganiselo obalwe ngokuyila.Amasebe emva kwe-valve ye-STAD ayanda kwaye ayancipha ngokulinganayo ngexesha elifanayo.Ivalve ye-static balance ihlangabezana nokuhamba komthwalo wenxenye phantsi kweemfuno zemozulu zangoku.Ngaphezu koko, imfuno yevalve yokulinganisa ye-STAD idlala indima kwibhalansi ye-thermal.
